1.1 About Your WiMAX Modem The WiMAX Modem has a built-in switch and one phone port. It allows you to access the Internet by connecting to a WiMAX wireless network. You can use a traditional analog telephone to make Internet calls using the WiMAX Modems Voice over IP (VoIP) communication capabilities. You can configure firewall and content filtering as well as a host of other features. The web browser-based Graphical User Interface (GUI), also known as the web configurator, provides easy management. See Chapter 21 on page 223 for a complete list of features for your model. 1.1.1 WiMAX Internet Access Connect your computer or network to the WiMAX Modem for WiMAX Internet access. See the Quick Start Guide for instructions on hardware connection. In a wireless metropolitan area network (MAN), the WiMAX Modem connects to a WiMAX base station (BS) for Internet access. The following diagram shows a notebook computer equipped with the WiMAX Modem connecting to the Internet through a WiMAX base station (marked BS). Figure 1 Mobile Station and Base Station When the firewall is on, all incoming traffic from the Internet to your network is blocked unless it is initiated from your network. Users Guide 31 Chapter 1Getting Started Use content filtering to block access to web sites with URLs containing keywords that you specify. You can define time periods and days during which content filtering is enabled and include or exclude particular computers on your network from content filtering. For example, you could block access to certain web sites for the kids. 1.1.2 Make Calls via Internet Telephony Service Provider In a home or small office environment, you can use the WiMAX Modem to make and receive the following types of VoIP telephone calls:
Peer-to-Peer calls - Use the WiMAX Modem to make a call directly to the recipients IP address without using a SIP proxy server. Figure 2 WiMAX Modems VoIP Features - Peer-to-Peer Calls Calls via a VoIP service provider - The WiMAX Modem sends your call to a VoIP service providers SIP server which forwards your calls to either VoIP or PSTN phones. Figure 3 WiMAX Modems VoIP Features - Calls via VoIP Service Provider 32 Users Guide 1.2 WiMAX Modem Hardware Follow the instructions in the Quick Start Guideto make hardware connections. Chapter 1Getting Started 1.2.1 LEDs The following figure shows the LEDs (lights) on the WiMAX Modem. Figure 4 The WiMAX Modems LEDs STRENGTH INDICATORS POWER VOICE WIMAX LINK The following table describes your WiMAX Modems LEDs (from right to left).

Change the password. Use a password thats not easy to guess and that consists of different types of characters, such as numbers and letters. Write down the password and put it in a safe place. Back up the configuration (and make sure you know how to restore it). Restoring an earlier working configuration may be useful if the WiMAX Modem becomes unstable or even crashes. If you forget your password, you will have to reset the WiMAX Modem to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the WiMAX Modem. You could simply restore your last configuration. 34 Users Guide CHAPTER 2 Introducing the Web Configurator 2.1 Overview The web configurator is an HTML-based management interface that allows easy device set up and management via any web browser that supports: HTML 4.0, CSS 2.0, and JavaScript 1.5, and higher.

The DHCP Client screen (Section 5.3 on page 55) to view connection information for clients configured by the WiMAX Modems internal DHCP server. The Time Setting screen (Section 5.4 on page 56) lets you configure your WiMAX Modems time and date keeping settings. 5.1.2 What You Need to Know The following terms and concepts may help as you read through this chapter. LAN A Local Area Network, or a shared communication system to which many computers are attached. A LAN, as its name implies, is limited to a local area such as a home or office environment. LANs have different topologies, the most common being the linear bus and the star configuration. IP Address IP addresses identify individual devices on a network. Every networking device
(including computers, servers, routers, printers, etc.) needs an IP address to communicate across the network. These networking devices are also known as hosts. Subnet Mask The subnet mask specifies the network number portion of an IP address. Your device will compute the subnet mask automatically based on the IP Address that Users Guide 53 Chapter 5The Setup Screens you entered. You do not need to change the computer subnet mask unless you are instructed to do so. Daytime A network protocol used by devices for debugging and time measurement. A computer can use this protocol to set its internal clock but only if it knows in which order the year, month, and day are returned by the server. Not all servers use the same format. Time A network protocol for retrieving the current time from a server. The computer issuing the command compares the time on its clock to the information returned by the server, adjusts itself automatically for time zone differences, then calculates the difference and corrects itself if there has been any temporal drift. NTP NTP stands for Network Time Protocol. It is employed by devices connected to the Internet in order to obtain a precise time setting from an official time server. These time servers are accurate to within 200 microseconds. 5.1.3 Before You Begin Make sure that you have made all the appropriate hardware connections to the WiMAX Modem, as described in the Quick Start Guide. Make sure that you have logged in to the web configurator at least one time and changed your password from the default, as described in the Quick Start Guide. 5.2 Set IP Address Click the SETUP icon in the navigation bar to set up the WiMAX Modems IP address and subnet mask.

It can use this list regardless of the time protocol you select. When the WiMAX Modem uses the list, it randomly selects one server and tries to synchronize with it. If the synchronization fails, then it goes through the rest of Users Guide 57 Chapter 5The Setup Screens the list in order until either it is successful or all the pre-defined NTP time servers have been tried.

You can configure its IP address and subnet mask, DHCP services, and other subnets. You can also control how the WiMAX Modem sends routing information using RIP. A Local Area Network (LAN) is a shared communication system to which many computers are attached. A LAN is usually a computer network limited to the immediate area, such as the same building or floor of a building. 6.1.1 What You Can Do in This Chapter The DHCP Setup screen (Section 6.2 on page 60) lets you enable, disable, and configure the DHCP server in the WiMAX Modem. The Static DHCP screen (Section 6.3 on page 62) lets you assign specific IP addresses to specific computers on the LAN. The IP Static Route screen (Section 6.4 on page 63) lets you examine the static routes configured in the WiMAX Modem. The Other Settings screen (Section 6.5 on page 65) lets you control the routing information that is sent and received by each subnet assign specific IP addresses to specific computers on the LAN. 6.1.2 What You Need to Know The following terms and concepts may help as you read through this chapter. IP Address IP addresses identify individual devices on a network. Every networking device
(including computers, servers, routers, printers, etc.) needs an IP address to communicate across the network. These networking devices are also known as hosts. Users Guide 59 Chapter 6The LAN Configuration Screens Subnet Masks Subnet masks determine the maximum number of possible hosts on a network. You can also use subnet masks to divide one network into multiple sub-networks. DNS DNS (Domain Name System) is for mapping a domain name to its corresponding IP address and vice versa. The DNS server is extremely important because without it, you must know the IP address of a networking device before you can access it. DHCP A DHCP (Dynamic Host Configuration Protocol) server can assign your WiMAX Modem an IP address, subnet mask, DNS and other routing information when its turned on. 6.2 DHCP Setup Click ADVANCED > LAN Configuration > DHCP Setup to enable, disable, and configure the DHCP server in the WiMAX Modem.

This field is related to RIP. The metric represents the "cost of transmission". A router determines the best route for transmission by choosing a path with the lowest
"cost". The smaller the metric, the lower the "cost". RIP uses hop count as the measurement of cost, where 1 is for a directly-connected network. The metric must be 1-15; if you use a value higher than 15, the routers assume the link is down. Click to save your changes.

None - The WiMAX Modem does not send or receive routing information on the subnet. Both - The WiMAX Modem sends and receives routing information on the subnet. In Only - The WiMAX Modem only receives routing information on the subnet. Out Only - The WiMAX Modem only sends routing information on the subnet. RIP Version Select which version of RIP the WiMAX Modem uses when it sends or receives information on the subnet. RIP-1 - The WiMAX Modem uses RIPv1 to exchange routing information. RIP-2B - The WiMAX Modem broadcasts RIPv2 to exchange routing information. RIP-2M - The WiMAX Modem multicasts RIPv2 to exchange routing information. Multicast You do not have to enable multicasting to use RIP-2M. (See RIP Version.) Select which version of IGMP the WiMAX Modem uses to support multicasting on the LAN. Multicasting sends packets to some computers on the LAN and is an alternative to unicasting (sending packets to one computer) and broadcasting (sending packets to every computer). None - The WiMAX Modem does not support multicasting. IGMP-v1 - The WiMAX Modem supports IGMP version 1. IGMP-v2 - The WiMAX Modem supports IGMP version 2. Multicasting can improve overall network performance. However, it requires extra processing and generates more network traffic. In addition, other computers on the LAN have to support the same version of IGMP. Click to save your changes. Click to restore your previously saved settings.

Where you obtain your network number depends on your particular situation. If the ISP or your network administrator assigns you a block of registered IP addresses, follow their instructions in selecting the IP addresses and the subnet mask. If the ISP did not explicitly give you an IP network number, then most likely you have a single user account and the ISP will assign you a dynamic IP address when the connection is established. If this is the case, it is recommended that you select a network number from 192.168.0.0 to 192.168.255.0 and you must enable the Network Address Translation (NAT) feature of the WiMAX Modem. The Internet Assigned Number Authority (IANA) reserved this block of addresses specifically for private use; please do not use any other number unless you are told otherwise. Let's say you select 192.168.1.0 as the network number; which covers 254 individual addresses, from 192.168.1.1 to 192.168.1.254 (zero and 255 are reserved). In other words, the first three numbers specify the network number while the last number identifies an individual computer on that network. Once you have decided on the network number, pick an IP address that is easy to remember, for instance, 192.168.1.1, for your WiMAX Modem, but make sure that no other device on your network is using that IP address. The subnet mask specifies the network number portion of an IP address. Your WiMAX Modem will compute the subnet mask automatically based on the IP address that you entered. You don't need to change the subnet mask computed by the WiMAX Modem unless you are instructed to do otherwise. 6.6.2 DHCP Setup DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual clients to obtain TCP/IP configuration at start-up from a server. You can configure the WiMAX Modem as a DHCP server or disable it. When configured as a server, the WiMAX Modem provides the TCP/IP configuration for the clients. If DHCP service is disabled, you must have another DHCP server on your LAN, or else each computer must be manually configured. The WiMAX Modem is pre-configured with a pool of IP addresses for the DHCP clients (DHCP Pool). See the product specifications in the appendices. Do not assign static IP addresses from the DHCP pool to your LAN computers. These parameters should work for the majority of installations. If your ISP gives you explicit DNS server address(es), see Section 6.3 on page 62. Users Guide 67 Chapter 6The LAN Configuration Screens 6.6.3 LAN TCP/IP The WiMAX Modem has built-in DHCP server capability that assigns IP addresses and DNS servers to systems that support DHCP client capability. These parameters should work for the majority of installations. If your ISP gives you explicit DNS server address(es), see Section 6.2 on page 60. 6.6.4 DNS Server Address DNS (Domain Name System) is for mapping a domain name to its corresponding IP address and vice versa. The DNS server is extremely important because without it, you must know the IP address of a machine before you can access it. The DNS server addresses that you enter in the DHCP setup are passed to the client machines along with the assigned IP address and subnet mask. There are two ways that an ISP disseminates the DNS server addresses. The first is for an ISP to tell a customer the DNS server addresses, usually in the form of an information sheet, when s/he signs up. If your ISP gives you the DNS server addresses, enter them in the DNS Server fields in DHCP Setup, otherwise, leave them blank. Some ISPs choose to pass the DNS servers using the DNS server extensions of PPP IPCP (IP Control Protocol) after the connection is up. If your ISP did not give you explicit DNS servers, chances are the DNS servers are conveyed through IPCP negotiation. The WiMAX Modem supports the IPCP DNS server extensions through the DNS proxy feature. If the Primary and Secondary DNS Server fields in the LAN Setup screen are notspecified, for instance, left as 0.0.0.0, the WiMAX Modem tells the DHCP clients that it itself is the DNS server. When a computer sends a DNS query to the WiMAX Modem, the WiMAX Modem forwards the query to the real DNS server learned through IPCP and relays the response back to the computer. Please note that DNS proxy works only when the ISP uses the IPCP DNS server extensions. It does not mean you can leave the DNS servers out of the DHCP setup under all circumstances. If your ISP gives you explicit DNS servers, make sure that you enter their IP addresses in the LAN Setup screen. This way, the WiMAX Modem can pass the DNS servers to the computers and the computers can query the DNS server directly without the WiMAX Modems intervention. 68 Users Guide 6.6.5 RIP Setup Chapter 6The LAN Configuration Screens RIP (Routing Information Protocol) allows a router to exchange routing information with other routers. The RIP Direction field controls the sending and receiving of RIP packets. When set to:
Both - the WiMAX Modem will broadcast its routing table periodically and incorporate the RIP information that it receives. In Only - the WiMAX Modem will not send any RIP packets but will accept all RIP packets received. Out Only - the WiMAX Modem will send out RIP packets but will not accept any RIP packets received. None - the WiMAX Modem will not send any RIP packets and will ignore any RIP packets received. The Version field controls the format and the broadcasting method of the RIP packets that the WiMAX Modem sends (it recognizes both formats when receiving). RIP-1 is universally supported; but RIP-2 carries more information. RIP-1 is probably adequate for most networks, unless you have an unusual network topology. Both RIP-2B and RIP-2M sends the routing data in RIP-2 format; the difference being that RIP-2B uses subnet broadcasting while RIP-2M uses multicasting. 6.6.6 Multicast Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender - 1 recipient) or Broadcast (1 sender - everybody on the network). Multicast delivers IP packets to a group of hosts on the network - not everybody and not just 1. IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to establish membership in a Multicast group - it is not used to carry user data. IGMP version 2 (RFC 2236) is an improvement over version 1 (RFC 1112) but IGMP version 1 is still in wide use. If you would like to read more detailed information about interoperability between IGMP version 2 and version 1, please see sections 4 and 5 of RFC 2236. The class D IP address is used to identify host groups and can be in the range 224.0.0.0 to 239.255.255.255. The address 224.0.0.0 is not assigned to any group and is used by IP multicast computers. The address 224.0.0.1 is used for query messages and is assigned to the permanent group of all IP hosts (including gateways). All hosts must join the 224.0.0.1 group in order to participate in IGMP. The address 224.0.0.2 is assigned to the multicast routers group. The WiMAX Modem supports both IGMP version 1 (IGMP-v1) and IGMP version 2
(IGMP-v2). At start up, the WiMAX Modem queries all directly connected Users Guide 69 Chapter 6The LAN Configuration Screens networks to gather group membership. After that, the WiMAX Modem periodically updates this information. IP multicasting can be enabled/disabled on the WiMAX Modem LAN and/or WAN interfaces in the web configurator (LAN; WAN). Select None to disable IP multicasting on these interfaces. 70 Users Guide CHAPTER 7 The WAN Configuration Screens 7.1 Overview Use the ADVANCED > WAN Configuration screens to set up your WiMAX Modems Wide Area Network (WAN) or Internet features. A Wide Area Network (or WAN) links geographically dispersed locations to other networks or the Internet. A WAN configuration can include switched and permanent telephone circuits, terrestrial radio systems and satellite systems. 7.1.1 What You Can Do in This Chapter The Internet Connection screen (Section 7.2 on page 74) lets you set up your WiMAX Modems Internet settings. The WiMAX Configuration screen (Section 7.3 on page 76) lets set up the frequencies used by your WiMAX Modem. The Advanced screen (Section 7.4 on page 81) lets configure your DNS server, RIP, Multicast and Windows Networking settings. 7.1.2 What You Need to Know The following terms and concepts may help as you read through this chapter. WiMAX WiMAX (Worldwide Interoperability for Microwave Access) is the IEEE 802.16 wireless networking standard, which provides high-bandwidth, wide-range wireless service across wireless Metropolitan Area Networks (MANs). In a wireless MAN, a wireless-equipped computer is known either as a mobile station (MS) or a subscriber station (SS). Mobile stations use the IEEE 802.16e standard and are able to maintain connectivity while switching their connection from one base station to another base station (handover) while subscriber stations use other standards that do not have this capability (IEEE 802.16-2004, for Users Guide 71 Chapter 7The WAN Configuration Screens example). The following figure shows an MS-equipped notebook computer MS1 moving from base station BS1s coverage area and connecting to BS2. Figure 24 WiMax: Mobile Station WiMAX technology uses radio signals (around 2 to 10 GHz) to connect subscriber stations and mobile stations to local base stations. Numerous subscriber stations and mobile stations connect to the network through a single base station (BS), as in the following figure. Figure 25 WiMAX: Multiple Mobile Stations A base station's coverage area can extend over many hundreds of meters, even under poor conditions. A base station provides network access to subscriber stations and mobile stations, and communicates with other base stations. The radio frequency and bandwidth of the link between the WiMAX Modem and the base station are controlled by the base station. The WiMAX Modem follows the base stations configuration. 72 Users Guide Chapter 7The WAN Configuration Screens Authentication When authenticating a user, the base station uses a third-party RADIUS or Diameter server known as an AAA (Authentication, Authorization and Accounting) server to authenticate the mobile or subscriber stations. The following figure shows a base station using an AAA server to authenticate mobile station MS, allowing it to access the Internet. Figure 26 Using an AAA Server In this figure, the dashed arrow shows the PKM (Privacy Key Management) secured connection between the mobile station and the base station, and the solid arrow shows the EAP secured connection between the mobile station, the base station and the AAA server.

In a WiMAX network, a mobile or subscriber station must use a radio frequency supported by the base station to communicate. When the WiMAX Modem looks for a connection to a base station, it can search a range of frequencies. 76 Users Guide Chapter 7The WAN Configuration Screens Radio frequency is measured in Hertz (Hz). Table 20 Radio Frequency Conversion 1 kHz = 1000 Hz 1 MHz = 1000 kHz (1000000 Hz) 1 GHz = 1000 MHz (1000000 kHz) Figure 28 ADVANCED > WAN Configuration >WiMAX Configuration The following table describes the labels in this screen.

DESCRIPTION 7.3.1 Frequency Ranges The following figure shows the WiMAX Modem searching a range of frequencies to find a connection to a base station. Figure 29 Frequency Ranges In this figure, A is the WiMAX frequency range. WiMAX frequency range refers to the entire range of frequencies the WiMAX Modem is capable of using to transmit and receive (see the Product Specifications appendix for details). In the figure, B shows the operator frequency range. This is the range of frequencies within the WiMAX frequency range supported by your operator
(service provider). The operator range is subdivided into bandwidth steps. In the figure, each C is a bandwidth step. The arrow D shows the WiMAX Modem searching for a connection. Have the WiMAX Modem search only certain frequencies by configuring the downlink frequencies. Your operator can give you information on the supported frequencies. The downlink frequencies are points of the frequency range your WiMAX Modem searches for an available connection. Use the Site Survey screen to set these bands. You can set the downlink frequencies anywhere within the WiMAX frequency range. In this example, the downlink frequencies have been set to search all of the operator range for a connection. 78 Users Guide 7.3.2 Configuring Frequency Settings Chapter 7The WAN Configuration Screens You need to set the WiMAX Modem to scan one or more specific radio frequencies to find an available connection to a WiMAX base station. Use the WiMAX Frequency screen to define the radio frequencies to be searched for available wireless connections. See Section 7.3.3 on page 79 for an example of using the WiMAX Frequency screen. Note: It may take several minutes for the WiMAX Modem to find a connection. The WiMAX Modem searches the DL Frequency settings in ascending numerical order, from [1] to [9]. Note: The Bandwidth field is not user-configurable; when the WiMAX Modem finds a WiMAX connection, its frequency is displayed in this field. If you enter a 0 in a DL Frequency field, the WiMAX Modem immediately moves on to the next DL Frequency field. When the WiMAX Modem connects to a base station, the values in this screen are automatically set to the base stations frequency. The next time the WiMAX Modem searches for a connection, it searches only this frequency. If you want the WiMAX Modem to search other frequencies, enter them in the DL Frequency fields. The following table describes some examples of DL Frequency settings. Table 22 DL Frequency Example Settings DL Frequency [1]

You can also enable and disable SIP, FTP, and H.323 ALG. Network Address Translation (NAT) maps a hosts IP address within one network to a different IP address in another network. For example, you can use a NAT router to map one IP address from your ISP to multiple private IP addresses for the devices in your home network. 8.1.1 What You Can Do in This Chapter The General screen (Section 8.2 on page 83) lets you enable or disable NAT and to allocate memory for NAT and firewall rules. The Port Forwarding screen (Section 8.3 on page 84) lets you look at the current port-forwarding rules in the WiMAX Modem, and to enable, disable, activate, and deactivate each one. The Trigger Port screen (Section 8.4 on page 88) lets you maintain trigger port forwarding rules for the WiMAX Modem. The ALG screen (Section 8.5 on page 91) lets you enable and disable SIP
(VoIP), FTP (file transfer), and H.323 (audio-visual) ALG in the WiMAX Modem. 8.2 General Click ADVANCED > NAT Configuration > General to enable or disable NAT and to allocate memory for NAT and firewall rules. Figure 32 ADVANCED > NAT Configuration > General Users Guide 83 Chapter 8The NAT Configuration Screens The following table describes the labels in this screen. Table 24 ADVANCED > NAT Configuration > General LABEL Enable Network Address Translation Max NAT/Firewall Session Per User DESCRIPTION Select this if you want to use port forwarding, trigger ports, or any of the ALG. When computers use peer to peer applications, such as file sharing applications, they may use a large number of NAT sessions. If you do not limit the number of NAT sessions a single client can establish, this can result in all of the available NAT sessions being used. In this case, no additional NAT sessions can be established, and users may not be able to access the Internet. Each NAT session establishes a corresponding firewall session. Use this field to limit the number of NAT/firewall sessions each client computer can establish through the WiMAX Modem. If your network has a small number of clients using peer to peer applications, you can raise this number to ensure that their performance is not degraded by the number of NAT sessions they can establish. If your network has a large number of users using peer to peer applications, you can lower this number to ensure no single client is using all of the available NAT sessions.

Use the ADVANCED > NAT Configuration > Port Forwarding screen to forward incoming service requests to the server(s) on your local network. You may enter a single port number or a range of port numbers to be forwarded, and the local IP address of the desired server. The port number identifies a service; for example, web service is on port 80 and FTP on port 21. In some cases, such as for unknown services or where one server can support more than one service (for example both FTP and web service), it might be better to specify a range of port numbers. In addition to the servers for specified services, NAT supports a default server. A service request that does not have a server explicitly designated for it is forwarded to the default server. If the default is not defined, the service request is simply discarded. 84 Users Guide Chapter 8The NAT Configuration Screens The following table describes the icons in this screen.

Server IP Address Apply CancelClick to return to the previous screen without saving your changes. Users Guide 87 Chapter 8The NAT Configuration Screens 8.4 Trigger Port Some services use a dedicated range of ports on the client side and a dedicated range of ports on the server side. With regular port forwarding you set a forwarding port in NAT to forward a service (coming in from the server on the WAN) to the IP address of a computer on the client side (LAN). The problem is that port forwarding only forwards a service to a single LAN IP address. In order to use the same service on a different LAN computer, you have to manually replace the LAN computer's IP address in the forwarding port with another LAN computer's IP address, Trigger port forwarding solves this problem by allowing computers on the LAN to dynamically take turns using the service. The WiMAX Modem records the IP address of a LAN computer that sends traffic to the WAN to request a service with a specific port number and protocol (a "trigger" port). When the WiMAX Modem's WAN port receives a response with a specific port number and protocol
("incoming" port), the WiMAX Modem forwards the traffic to the LAN IP address of the computer that sent the request. After that computers connection for that service closes, another computer on the LAN can use the service in the same manner. This way you do not need to configure a new IP address each time you want a different LAN computer to use the application.

Users Guide 89 Chapter 8The NAT Configuration Screens 8.4.1 Trigger Port Forwarding Example The following is an example of trigger port forwarding. In this example, J is Janes computer and S is the Real Audio server. Figure 37 Trigger Port Forwarding Example 1 2 3 4 Jane requests a file from the Real Audio server (port 7070). Port 7070 is a trigger port and causes the WiMAX Modem to record Janes computer IP address. The WiMAX Modem associates Jane's computer IP address with the "incoming" port range of 6970-7170. The Real Audio server responds using a port number ranging between 6970-7170. The WiMAX Modem forwards the traffic to Janes computer IP address. 5 Only Jane can connect to the Real Audio server until the connection is closed or times out. The WiMAX Modem times out in three minutes with UDP (User Datagram Protocol), or two hours with TCP/IP (Transfer Control Protocol/Internet Protocol). Two points to remember about trigger ports:
1 2 Trigger events only happen on data that is coming from inside the WiMAX Modem and going to the outside. If an application needs a continuous data stream, that port (range) will be tied up so that another computer on the LAN cant trigger it. 90 Users Guide 8.5 ALG Chapter 8The NAT Configuration Screens Some applications, such as SIP, cannot operate through NAT (are NAT un-friendly) because they embed IP addresses and port numbers in their packets data payload. Some NAT routers may include a SIP Application Layer Gateway (ALG). An Application Layer Gateway (ALG) manages a specific protocol (such as SIP, H.323 or FTP) at the application layer. A SIP ALG allows SIP calls to pass through NAT by examining and translating IP addresses embedded in the data stream. Click ADVANCED > NAT Configuration > ALG to enable and disable SIP (VoIP), FTP (file transfer), and H.323 (audio-visual) ALG in the WiMAX Modem.

System Name The System Name is often used for identification purposes. Because some ISPs check this name you should enter your computer's "Computer Name". Users Guide 93 Chapter 9The System Configuration Screens In Windows 2000: Click Start > Settings > Control Panel and then double-
click the System icon. Select the Network Identification tab and then click the Properties button. Note the entry for the Computer Name field and enter it as the System Name. In Windows XP: Click Start > My Computer > View system information and then click the Computer Name tab. Note the entry in the Full computer name field and enter it as the WiMAX Modem System Name. Domain Name The Domain Name entry is what is propagated to the DHCP clients on the LAN. If you leave this blank, the domain name obtained by DHCP from the ISP is used. While you must enter the host name (System Name) on each individual computer, the domain name can be assigned from the WiMAX Modem via DHCP. DNS Server Address Assignment Use DNS (Domain Name System) to map a domain name to its corresponding IP address and vice versa. The DNS server is extremely important because without it, you must know the IP address of a computer before you can access it. The WiMAX Modem can get the DNS server addresses in the following ways:
1 2 The ISP tells you the DNS server addresses, usually in the form of an information sheet, when you sign up. If your ISP gives you DNS server addresses, enter them in the DNS Server fields in the SYSTEM General screen. If the ISP did not give you DNS server information, leave the DNS Server fields in the SYSTEM General screen set to 0.0.0.0 for the ISP to dynamically assign the DNS server IP addresses. 94 Users Guide Chapter 9The System Configuration Screens 9.2 General Click ADVANCED > System Configuration > General to change the WiMAX Modems mode, set up its system name, domain name, idle timeout, and administrator password.

If you leave this blank, the domain name obtained from the ISP is used. Use up to 38 alphanumeric characters. Spaces are not allowed, but dashes - and periods "." are accepted. Enter the number of minutes a management session can be left idle before the session times out. After it times out, you have to log in again. A value of "0" means a management session never times out, no matter how long it has been left idle. This is not recommended. Long idle timeouts may have security risks. The default is five minutes. Password Setup Old PasswordEnter the current password you use to access the WiMAX Modem. New PasswordEnter the new password for the WiMAX Modem. You can use up to 30 characters.

ResetClick to restore your previously saved settings. DESCRIPTION Enter the new password again. 9.3 Dynamic DNS Dynamic DNS allows you to update your current dynamic IP address with one or many dynamic DNS services so that anyone can contact you (in NetMeeting, CU-
SeeMe, etc.). You can also access your FTP server or Web site on your own computer using a domain name (for instance myhost.dhs.org, where myhost is a name of your choice) that will never change instead of using an IP address that changes each time you reconnect. Your friends or relatives will always be able to call you even if they don't know your IP address. First of all, you need to have registered a dynamic DNS account with www.dyndns.org. This is for people with a dynamic IP from their ISP or DHCP server that would still like to have a domain name. The Dynamic DNS service provider will give you a password or key. Enabling the wildcard feature for your host causes *.yourhost.dyndns.org to be aliased to the same IP address as yourhost.dyndns.org. This feature is useful if you want to be able to use, for example, www.yourhost.dyndns.org and still reach your hostname. Note: If you have a private WAN IP address, then you cannot use Dynamic DNS. 96 Users Guide Chapter 9The System Configuration Screens Click ADVANCED > System Configuration > Dynamic DNS to set up the WiMAX Modem as a dynamic DNS client.

VoIP (Voice over IP) is the sending of voice signals over the Internet Protocol. This allows you to make phone calls and send faxes over the Internet at a fraction of the cost of using the traditional circuit-switched telephone network. You can also use servers to run telephone service applications like PBX services and voice mail. Internet Telephony Service Provider (ITSP) companies provide VoIP service. A company could alternatively set up an IP-PBX and provide its own VoIP service. Circuit-switched telephone networks require 64 kilobits per second (kbps) in each direction to handle a telephone call. VoIP can use advanced voice coding techniques with compression to reduce the required bandwidth. 10.1.1 What You Can Do in This Chapter The SIP Settings screen (Section 10.2 on page 105) lets you setup and maintain your SIP account(s) in the WiMAX Modem. The Advanced SIP Settings screen (Section 10.2.1 on page 107) lets you set up and maintain advanced settings for each SIP account The QoS screen (Section 10.3 on page 113) lets you set up and maintain ToS and VLAN settings for the WiMAX Modem. 10.1.2 What You Need to Know The following terms and concepts may help as you read through this chapter. SIP The Session Initiation Protocol (SIP) is an application-layer control (signaling) protocol that handles the setting up, altering and tearing down of voice and Users Guide 103 Chapter 10The Service Configuration Screens multimedia sessions over the Internet. SIP signaling is separate from the media for which it handles sessions. The media that is exchanged during the session can use a different path from that of the signaling. SIP handles telephone calls and can interface with traditional circuit-switched telephone networks. SIP Identities A SIP account uses an identity (sometimes referred to as a SIP address). A complete SIP identity is called a SIP URI (Uniform Resource Identifier). A SIP account's URI identifies the SIP account in a way similar to the way an e-mail address identifies an e-mail account. The format of a SIP identity is SIP-
Number@SIP-Service-Domain. SIP Number The SIP number is the part of the SIP URI that comes before the @ symbol. A SIP number can use letters like in an e-mail address (johndoe@your-ITSP.com for example) or numbers like a telephone number (1122334455@VoIP-provider.com for example). SIP Service Domain The SIP service domain of the VoIP service provider (the company that lets you make phone calls over the Internet) is the domain name in a SIP URI. For example, if the SIP address is 1122334455@VoIP-provider.com, then VoIP-
provider.com is the SIP service domain. SIP Register Server A SIP register server maintains a database of SIP identity-to-IP address (or domain name) mapping. The register server checks your user name and password when you register. RTP When you make a VoIP call using SIP, the RTP (Real time Transport Protocol) is used to handle voice data transfer. See RFC 1889 for details on RTP. Use NAT If you know the NAT routers public IP address and SIP port number, you can use the Use NAT feature to manually configure the WiMAX Modem to use a them in the SIP messages. This eliminates the need for STUN or a SIP ALG. You must also configure the NAT router to forward traffic with this port number to the WiMAX Modem. 104 Users Guide Chapter 10The Service Configuration Screens 10.1.3 Before you Begin Ensure that you have all of your voice account information on hand. If not, contact your voice account service provider to find out which settings in this chapter you should configure in order to use your telephone with the WiMAX Modem. Connect your WiMAX Modem to the Internet, as described in the Quick Start Guide. If you have not already done so, then you will not be able to test your VoIP settings. 10.2 SIP Settings Click VOICE > Service Configuration > SIP Setting to setup and maintain your SIP account(s) in the WiMAX Modem.

STUN also allows the WiMAX Modem to find the public IP address that NAT assigned, so the WiMAX Modem can embed it in the SIP data stream. STUN does not work with symmetric NAT routers or firewalls. See RFC 3489 for details on STUN. The following figure shows how STUN works. 1 2 3 The WiMAX Modem (A) sends SIP packets to the STUN server (B). The STUN server (B) finds the public IP address and port number that the NAT router used on the WiMAX Modems SIP packets and sends them to the WiMAX Modem. The WiMAX Modem uses the public IP address and port number in the SIP packets that it sends to the SIP server (C). Figure 46 STUN Example 1 NAT B C A 10.2.1.2 Outbound Proxy Your VoIP service provider may host a SIP outbound proxy server to handle all of the WiMAX Modems VoIP traffic. This allows the WiMAX Modem to work with any type of NAT router and eliminates the need for STUN or a SIP ALG. Turn off a SIP ALG on a NAT router in front of the WiMAX Modem to keep it from re-translating the IP address (since this is already handled by the outbound proxy server). 10.2.1.3 Voice Coding A codec (coder/decoder) codes analog voice signals into digital signals and decodes the digital signals back into voice signals. The WiMAX Modem supports the following codecs. Users Guide 107 Chapter 10The Service Configuration Screens G.711 is a Pulse Code Modulation (PCM) waveform codec. PCM measures analog signal amplitudes at regular time intervals (sampling) and converts them into digital bits (quantization). Quantization reads the analog signal and then writes it to the nearest digital value. For this reason, a digital sample is usually slightly different from its analog original (this difference is known as quantization noise). G.711 provides excellent sound quality but requires 64kbps of bandwidth. G.723 is an Adaptive Differential Pulse Code Modulation (ADPCM) waveform codec. Differential (or Delta) PCM is similar to PCM, but encodes the audio signal based on the difference between one sample and a prediction based on previous samples, rather than encoding the samples actual quantized value. Many thousands of samples are taken each second, and the differences between consecutive samples are usually quite small, so this saves space and reduces the bandwidth necessary. However, DPCM produces a high quality signal (high signal-to-noise ratio or SNR) for high difference signals (where the actual signal is very different from what was predicted) but a poor quality signal (low SNR) for low difference signals (where the actual signal is very similar to what was predicted). This is because the level of quantization noise is the same at all signal levels. Adaptive DPCM solves this problem by adapting the difference signals level of quantization according to the audio signals strength. A low difference signal is given a higher quantization level, increasing its signal-to-noise ratio. This provides a similar sound quality at all signal levels. G.723 provides high quality sound and requires 20 or 40 kbps. G.729 is an Analysis-by-Synthesis (AbS) hybrid waveform codec. It uses a filter based on information about how the human vocal tract produces sounds. The codec analyzes the incoming voice signal and attempts to synthesize it using its list of voice elements. It tests the synthesized signal against the original and, if it is acceptable, transmits details of the voice elements it used to make the synthesis. Because the codec at the receiving end has the same list, it can exactly recreate the synthesized audio signal.G.729 provides good sound quality and reduces the required bandwidth to 8kbps. 10.2.1.4 MWI (Message Waiting Indication) Enable Message Waiting Indication (MWI) enables your phone to give you a messagewaiting (beeping) dial tone when you have one or more voice messages. Your VoIP service provider must have a messaging system that sends message-
waiting-status SIP packets as defined in RFC 3842. 108 Users Guide Chapter 10The Service Configuration Screens 10.2.1.5 Advanced SIP Settings Options Click Advanced in VOICE > Service Configuration > SIP Settings to set up and maintain advanced settings for each SIP account.

Min-SEEnter the minimum number of seconds the WiMAX Modem accepts for a session expiration time when it receives a request to start a SIP session. If the request has a shorter time, the WiMAX Modem rejects it. RTP Port Range Start Port End Port Enter the listening port number(s) for RTP traffic, if your VoIP service provider gave you this information. Otherwise, keep the default values. To enter one port number, enter the port number in the Start Port and End Port fields. To enter a range of ports:
Type the port number at the beginning of the range in the Start Port field Type the port number at the end of the range in the End Port field. Voice Compression Primary, Secondary, and Third Compression Select the type of voice coder/decoder (codec) that you want the WiMAX Modem to use. G.711 provides high voice quality but requires more bandwidth (64 kbps). DTMF Mode G.711A is typically used in Europe. G.711u is typically used in North America and Japan. G.723 provides good voice quality, and requires 20 or 40 kbps. G.729 requires only 8 kbps. The WiMAX Modem must use the same codec as the peer. When two SIP devices start a SIP session, they must agree on a codec. For more on voice compression, see Voice Coding on page107 Control how the WiMAX Modem handles the tones that your telephone makes when you push its buttons. You should use the same mode your VoIP service provider uses. RFC 2833 - send the DTMF tones in RTP packets PCM - send the DTMF tones in the voice data stream. This method works best when you are using a codec that does not use compression (like G.711). Codecs that use compression (like G.729) can distort the tones. SIP INFO - send the DTMF tones in SIP messages STUN ActiveSelect this if all of the following conditions are satisfied. There is a NAT router between the WiMAX Modem and the SIP server. The NAT router is not a SIP ALG. Your VoIP service provider gave you an IP address or domain name for a STUN server.

Virtual Local Area Network (VLAN) allows a physical network to be partitioned into multiple logical networks. Only stations within the same group can communicate with each other. Your WiMAX Modem can add IEEE 802.1Q VLAN ID tags to voice frames that it sends to the network. This allows the WiMAX Modem to communicate with a SIP Users Guide 113 Chapter 10The Service Configuration Screens server that is a member of the same VLAN group. Some ISPs use the VLAN tag to identify voice traffic and give it priority over other traffic. Click VOICE > Service Configuration > QoS to set up and maintain ToS and VLAN settings for the WiMAX Modem. QoS (Quality of Service) refers to both a network's ability to deliver data with minimum delay and the networking methods used to provide bandwidth for real-time multimedia applications.

A calls B. Table 40 SIP Call Progression A 1. INVITE B 4. ACK 6. BYE 5.Dialogue (voice traffic) 2. Ringing 3. OK 7. OK 1 A sends a SIP INVITE request to B. This message is an invitation for B to participate in a SIP telephone call. 2 B sends a response indicating that the telephone is ringing. 3 B sends an OK response after the call is answered. 4 A then sends an ACK message to acknowledge that B has answered the call. 5 Now A and B exchange voice media (talk). 6 After talking, A hangs up and sends a BYE request. 7 B replies with an OK response confirming receipt of the BYE request and the call is terminated. Users Guide 115 Chapter 10The Service Configuration Screens 10.4.2 SIP Client Server SIP is a client-server protocol. A SIP client is an application program or device that sends SIP requests. A SIP server responds to the SIP requests. When you use SIP to make a VoIP call, it originates at a client and terminates at a server. A SIP client could be a computer or a SIP phone. One device can act as both a SIP client and a SIP server. 10.4.3 SIP User Agent A SIP user agent can make and receive VoIP telephone calls. This means that SIP can be used for peer-to-peer communications even though it is a client-server protocol. In the following figure, either A or B can act as a SIP user agent client to initiate a call. A and B can also both act as a SIP user agent to receive the call. Figure 49 SIP User Agent A B 10.4.4 SIP Proxy Server A SIP proxy server receives requests from clients and forwards them to another server. In the following example, you want to use client device A to call someone who is using client device C. 1 The client device (A in the figure) sends a call invitation to the SIP proxy server
(B). 116 Users Guide Chapter 10The Service Configuration Screens 2 The SIP proxy server forwards the call invitation to C. Figure 50 SIP Proxy Server B 1 2 A C 10.4.5 SIP Redirect Server A SIP redirect server accepts SIP requests, translates the destination address to an IP address and sends the translated IP address back to the device that sent the request. Then the client device that originally sent the request can send requests to the IP address that it received back from the redirect server. Redirect servers do not initiate SIP requests. In the following example, you want to use client device A to call someone who is using client device C. 1 Client device A sends a call invitation for C to the SIP redirect server (B). 2 The SIP redirect server sends the invitation back to A with Cs IP address (or domain name). Users Guide 117 Chapter 10The Service Configuration Screens 3 Client device A then sends the call invitation to client device C. Figure 51 SIP Redirect Server A 3 1 2 C 10.4.6 NAT and SIP B The WiMAX Modem must register its public IP address with a SIP register server. If there is a NAT router between the WiMAX Modem and the SIP register server, the WiMAX Modem probably has a private IP address. The WiMAX Modem lists its IP address in the SIP message that it sends to the SIP register server. NAT does not translate this IP address in the SIP message. The SIP register server gets the WiMAX Modems IP address from inside the SIP message and maps it to your SIP identity. If the WiMAX Modem has a private IP address listed in the SIP message, the SIP server cannot map it to your SIP identity. See Chapter8 The NAT Configuration Screens for more information. Use a SIP ALG (Application Layer Gateway), Use NAT, STUN, or outbound proxy to allow the WiMAX Modem to list its public IP address in the SIP messages. 10.4.7 DiffServ DiffServ is a class of service (CoS) model that marks packets so that they receive specific per-hop treatment at DiffServ-compliant network devices along the route based on the application types and traffic flow. Packets are marked with DiffServ Code Points (DSCPs) indicating the level of service desired. This allows the intermediary DiffServ-compliant network devices to handle the packets differently depending on the code points without the need to negotiate paths or remember state information for every flow. In addition, applications do not have to request a particular service or give advanced notice of where the traffic is going. 118 Users Guide Chapter 10The Service Configuration Screens 10.4.8 DSCP and Per-Hop Behavior DiffServ defines a new DS (Differentiated Services) field to replace the Type of Service (TOS) field in the IP header. The DS field contains a 2-bit unused field and a 6-bit DSCP field which can define up to 64 service levels. The following figure illustrates the DS field. Figure 52 DiffServ: Differentiated Service Field DSCP
(6-bit) Unused
(2-bit) DSCP is backward compatible with the three precedence bits in the ToS octet so that non-DiffServ compliant, ToS-enabled network device will not conflict with the DSCP mapping. The DSCP value determines the forwarding behavior, the PHB (Per-Hop Behavior), that each packet gets across the DiffServ network. Based on the marking rule, different kinds of traffic can be marked for different priorities of forwarding. Resources can then be allocated according to the DSCP values and the configured policies.

You can also select which SIP account to use for making outgoing calls. 11.1.1 What You Can Do in This Chapter The Analog Phone screen (Section 11.2 on page 122) lets you control which SIP accounts each phone uses. The Common screen (Section 11.3 on page 124) lets you activate and deactivate immediate dialing. The Region screen (Section 11.4 on page 125) lets you maintain settings that often depend on the region of the world in which the WiMAX Modem is located. 11.1.2 What You Need to Know The following terms and concepts may help as you read through this chapter. Voice Activity Detection/Silence Suppression/Comfort Noise Voice Activity Detection (VAD) detects whether or not speech is present. This lets the WiMAX Modem reduce the bandwidth that a call uses by not transmitting silent packets when you are not speaking. When using VAD, the WiMAX Modem generates comfort noise when the other party is not speaking. The comfort noise lets you know that the line is still connected as total silence could easily be mistaken for a lost connection. Echo Cancellation G.168 is an ITU-T standard for eliminating the echo caused by the sound of your voice reverberating in the telephone receiver while you talk. Users Guide 121 Chapter 11The Phone Screens Supplementary Phone Services Overview Supplementary services such as call hold, call waiting, call transfer, etc. are generally available from your VoIP service provider.

Speed Dial and Peer-to-Peer Calling Speed dial provides shortcuts for dialing frequently used (VoIP) phone numbers. It is also required if you want to make peer-to-peer calls. In peer-to-peer calls, you call another VoIP device directly without going through a SIP server. In the WiMAX Modem, you must set up a speed dial entry in the phone book in order to do this. Select Non-Proxy (Use IP or URL) in the Type column and enter the callees IP address or domain name. The WiMAX Modem sends SIP INVITE requests to the peer VoIP device when you use the speed dial entry. You do not need to configure a SIP account in order to make a peer-to-peer VoIP call.

Users Guide 135 Chapter 12The Phone Book Screens 136 Users Guide CHAPTER 13 The Certificates Screens 13.1 Overview Use the TOOLS > Certificates screens to manage public key certificates on the WiMAX Modem. The WiMAX Modem can use public key certificates (also sometimes called digital IDs) to authenticate users. Certificates are based on public-private key pairs. A certificate contains the certificate owners identity and public key. Certificates provide a way to exchange public keys for use in authentication. Public key certificates are used by web browsers to ensure that a secure web site is legitimate. When a certificate authority such as VeriSign, Comodo, or Network Solutions (to name a few) receives a certificate request from a website operator, they confirm that the web domain and contact information in the request match those on public record with a domain name registrar. If they match, then the certificate is issued to the website operator, who then places it on his site to be issued to all visiting web browsers to let them know that the site is legitimate. 13.1.1 What You Can Do in This Chapter The My Certificates screen (Section 13.2 on page 138) lets you generate and export self-signed certificates or certification requests and import the WiMAX Modems CA-signed certificates. The Trusted CAs screen (Section 13.3 on page 147) lets you display a summary list of certificates of the certification authorities that you have set the WiMAX Modem to accept as trusted. 13.1.2 What You Need to Know The following terms and concepts may help as you read through this chapter. Certificate Authorities A Certification Authority (CA) issues certificates and guarantees the identity of each certificate owner. There are commercial certification authorities like CyberTrust or VeriSign and government certification authorities. You can use the Users Guide 137 Chapter 13The Certificates Screens WiMAX Modem to generate certification requests that contain identifying information and public keys and then send the certification requests to a certification authority. 13.2 My Certificates Click TOOLS > Certificates > My Certificates to access this screen.

One key is public and can be made openly available. The other key is private and must be kept secure. These keys work like a handwritten signature (in fact, certificates are often referred to as digital signatures). Only you can write your signature exactly as it ought to look. When people know what your signature ought to look like, they can verify whether something was signed by you, or by someone else. In the same way, your private key writes your digital signature and your public key allows people to verify whether data was signed by you, or by someone else. This process works as follows. 1 2 3 4 Tim wants to send a message to Jenny. He needs her to be sure that it comes from him, and that the message content has not been altered by anyone else along the way. Tim generates a public key pair (one public key and one private key). Tim keeps the private key and makes the public key openly available. This means that anyone who receives a message seeming to come from Tim can read it and verify whether it is really from him or not. Tim uses his private key to sign the message and sends it to Jenny. Jenny receives the message and uses Tims public key to verify it. Jenny knows that the message is from Tim, and she knows that although other people may have been able to read the message, no-one can have altered it (because they cannot re-sign the message with Tims private key). 5 Additionally, Jenny uses her own private key to sign a message and Tim uses Jennys public key to verify the message. The WiMAX Modem uses certificates based on public-key cryptology to authenticate users attempting to establish a connection, not to encrypt the data that you send after establishing a connection. The method used to secure the data that you send through an established connection depends on the type of connection. For example, a VPN tunnel might use the triple DES encryption algorithm. The certification authority uses its private key to sign certificates. Anyone can then use the certification authoritys public key to verify the certificates. A certification path is the hierarchy of certification authority certificates that validate a certificate. The WiMAX Modem does not trust a certificate if any certificate on its path has expired or been revoked. Users Guide 153 Chapter 13The Certificates Screens Certification authorities maintain directory servers with databases of valid and revoked certificates. A directory of certificates that have been revoked before the scheduled expiration is called a CRL (Certificate Revocation List). The WiMAX Modem can check a peers certificate against a directory servers list of revoked certificates. The framework of servers, software, procedures and policies that handles keys is called PKI (public-key infrastructure). 13.4.1.1 Advantages of Certificates Certificates offer the following benefits. The WiMAX Modem only has to store the certificates of the certification authorities that you decide to trust, no matter how many devices you need to authenticate. Key distribution is simple and very secure since you can freely distribute public keys and you never need to transmit private keys. 13.4.1.2 Self-signed Certificates You can have the WiMAX Modem act as a certification authority and sign its own certificates. 13.4.1.3 Factory Default Certificate The WiMAX Modem generates its own unique self-signed certificate when you first turn it on. This certificate is referred to in the GUI as the factory default certificate. 13.4.1.4 Certificate File Formats Any certificate that you want to import has to be in one of these file formats:
Binary X.509: This is an ITU-T recommendation that defines the formats for X.509 certificates. PEM (Base-64) encoded X.509: This Privacy Enhanced Mail format uses lowercase letters, uppercase letters and numerals to convert a binary X.509 certificate into a printable form. Binary PKCS#7: This is a standard that defines the general syntax for data
(including digital signatures) that may be encrypted. A PKCS #7 file is used to transfer a public key certificate. The private key is not included. The WiMAX Modem currently allows the importation of a PKS#7 file that contains a single certificate. PEM (Base-64) encoded PKCS#7: This Privacy Enhanced Mail (PEM) format uses lowercase letters, uppercase letters and numerals to convert a binary PKCS#7 certificate into a printable form. Note: Be careful to not convert a binary file to text during the transfer process. It is easy for this to occur since many programs use text files by default. 154 Users Guide Chapter 13The Certificates Screens 13.4.2 Verifying a Certificate Before you import a certificate into the WiMAX Modem, you should verify that you have the correct certificate. This is especially true of trusted certificates since the WiMAX Modem also trusts any valid certificate signed by any of the imported trusted certificates. 13.4.2.1 Checking the Fingerprint of a Certificate on Your Computer A certificates fingerprints are message digests calculated using the MD5 or SHA1 algorithms. The following procedure describes how to check a certificates fingerprint to verify that you have the actual certificate. 1 Browse to where you have the certificate saved on your computer. 2 Make sure that the certificate has a .cer or .crt file name extension. (On some Linux distributions, the file extension may be .der.) Figure 66 Remote Host Certificates Users Guide 155 Chapter 13The Certificates Screens 3 Double-click the certificates icon to open the Certificate window. Click the Details tab and scroll down to the Thumbprint Algorithm and Thumbprint fields. Figure 67 Certificate Details 4 Use a secure method to verify that the certificate owner has the same information in the Thumbprint Algorithm and Thumbprint fields. The secure method may very based on your situation. Possible examples would be over the telephone or through an HTTPS connection. 156 Users Guide CHAPTER 14 The Firewall Screens 14.1 Overview Use the TOOLS > Firewall screens to manage WiMAX Modems firewall security measures. Originally, the term firewall referred to a construction technique designed to prevent the spread of fire from one room to another. The networking term
"firewall" is a system or group of systems that enforces an access-control policy between two networks. It may also be defined as a mechanism used to protect a trusted network from an untrusted network. Of course, firewalls cannot solve every security problem. A firewall is one of the mechanisms used to establish a network security perimeter in support of a network security policy. It should never be the only mechanism or method employed. For a firewall to guard effectively, you must design and deploy it appropriately. This requires integrating the firewall into a broad information-
security policy. In addition, specific policies must be implemented within the firewall itself. 14.1.1 What You Can Do in This Chapter The General screen (Section 14.2 on page 158) lets you configure the basic settings for your firewall. The Services screen (Section 14.3 on page 161) lets you enable service blocking, set up the date and time service blocking is effective, and to maintain the list of services you want to block. 14.1.2 What You Need to Know The following terms and concepts may help as you read through this chapter. About the WiMAX Modem Firewall The WiMAX Modem firewall is a stateful inspection firewall and is designed to protect against Denial of Service attacks when activated. The WiMAX Modem's purpose is to allow a private Local Area Network (LAN) to be securely connected to Users Guide 157 Chapter 14The Firewall Screens the Internet. The WiMAX Modem can be used to prevent theft, destruction and modification of data, as well as log events, which may be important to the security of your network. The WiMAX Modem is installed between the LAN and a WiMAX base station connecting to the Internet. This allows it to act as a secure gateway for all data passing between the Internet and the LAN. The WiMAX Modem has one Ethernet (LAN) port. The LAN (Local Area Network) port attaches to a network of computers, which needs security from the outside world. These computers will have access to Internet services such as e-mail, FTP and the World Wide Web. However, inbound access is not allowed (by default) unless the remote host is authorized to use a specific service. 14.2 Firewall Setting This section describes firewalls and the built-in WiMAX Modems firewall features. 14.2.1 Firewall Rule Directions Figure 68 Firewall Rule Directions LAN-to-WAN rules are local network to Internet firewall rules. The default is to forward all traffic from your local network to the Internet. You can block certain LAN-to-WAN traffic in the Services screen (click the Services tab). All services displayed in the Blocked Services list box are LAN-
to-WAN firewall rules that block those services originating from the LAN. Blocked LAN-to-WAN packets are considered alerts. Alerts are higher priority logs that include system errors, attacks and attempted access to blocked web sites. Alerts appear in red in the View Log screen. You may choose to have alerts e-mailed immediately in the Log Settings screen. 158 Users Guide Chapter 14The Firewall Screens LAN-to-LAN/WiMAX Modem means the LAN to the WiMAX Modem LAN interface. This is always allowed, as this is how you manage the WiMAX Modem from your local computer. WAN-to-LAN rules are Internet to your local network firewall rules. The default is to block all traffic from the Internet to your local network. How can you forward certain WAN to LAN traffic? You may allow traffic originating from the WAN to be forwarded to the LAN by:
Configuring NAT port forwarding rules. Configuring WAN or LAN & WAN access for services in the Remote MGMT screens or SMT menus. When you allow remote management from the WAN, you are actually configuring WAN-to-WAN/WiMAX Modem firewall rules. WAN-
to-WAN/WiMAX Modem firewall rules are Internet to the WiMAX Modem WAN interface firewall rules. The default is to block all such traffic. When you decide what WAN-to-LAN packets to log, you are in fact deciding what WAN-to-LAN and WAN-to-WAN/WiMAX Modem packets to log. Forwarded WAN-to-LAN packets are not considered alerts. 14.2.2 Triangle Route When the firewall is on, your WiMAX Modem acts as a secure gateway between your LAN and the Internet. In an ideal network topology, all incoming and outgoing network traffic passes through the WiMAX Modem to protect your LAN against attacks. Figure 69 Ideal Firewall Setup Users Guide 159 Chapter 14The Firewall Screens 14.2.3 Firewall Setting Options Click TOOLS > Firewall > Firewall Setting to configure the basic settings for your firewall.

Stateful inspection firewalls restrict access by screening data packets against defined access rules. They make access control decisions based on IP address and protocol. They also "inspect" the session data to assure the integrity of the connection and to adapt to dynamic protocols. These firewalls generally provide the best speed and transparency; however, they may lack the granular application level access control or caching that some proxies support. Firewalls, of one type or another, have become an integral part of standard security solutions for enterprises. 162 Users Guide 14.4.2 Guidelines For Enhancing Security With Your Firewall Chapter 14The Firewall Screens 1 Change the default password via web configurator. 2 3 Think about access control before you connect to the network in any way. Limit who can access your router. 4 Don't enable any local service (such as Telnet or FTP) that you don't use. Any enabled service could present a potential security risk. A determined hacker might be able to find creative ways to misuse the enabled services to access the firewall or the network. 5 6 For local services that are enabled, protect against misuse. Protect by configuring the services to communicate only with specific peers, and protect by configuring rules to block packets for the services at specific interfaces. Protect against IP spoofing by making sure the firewall is active. 7 Keep the firewall in a secured (locked) room. 14.4.3 The Triangle Route Problem A traffic route is a path for sending or receiving data packets between two Ethernet devices. You may have more than one connection to the Internet
(through one or more ISPs). If an alternate gateway is on the LAN (and its IP address is in the same subnet as the WiMAX Modems LAN IP address), the triangle route (also called asymmetrical route) problem may occur. The steps below describe the triangle route problem. 1 A computer on the LAN initiates a connection by sending out a SYN packet to a receiving server on the WAN. 2 3 The WiMAX Modem reroutes the SYN packet through Gateway A on the LAN to the WAN. The reply from the WAN goes directly to the computer on the LAN without going through the WiMAX Modem. Users Guide 163 Chapter 14The Firewall Screens As a result, the WiMAX Modem resets the connection, as the connection has not been acknowledged. Figure 72 Triangle Route Problem 14.4.3.1 Solving the Triangle Route Problem If you have the WiMAX Modem allow triangle route sessions, traffic from the WAN can go directly to a LAN computer without passing through the WiMAX Modem and its firewall protection. Another solution is to use IP alias. IP alias allows you to partition your network into logical sections over the same Ethernet interface. Your WiMAX Modem supports up to three logical LAN interfaces with the WiMAX Modem being the gateway for each logical network. Its like having multiple LAN networks that actually use the same physical cables and ports. By putting your LAN and Gateway A in different subnets, all returning network traffic must pass through the WiMAX Modem to your LAN. The following steps describe such a scenario. 1 A computer on the LAN initiates a connection by sending a SYN packet to a receiving server on the WAN. 2 3 The WiMAX Modemreroutes the packet to Gateway A, which is in Subnet 2. The reply from the WAN goes to the WiMAX Modem. 164 Users Guide 4 The WiMAX Modem then sends it to the computer on the LAN in Subnet 1.

Content filtering is the ability to block certain web features or specific URL keywords. The WiMAX Modem can block web features such as ActiveX controls, Java applets, cookies and disable web proxies. The WiMAX Modem also allows you to define time periods and days during which the WiMAX Modem performs content filtering. 15.1.1 What You Can Do in This Chapter The Filter screen (Section 15.2 on page 168) lets you set up a trusted IP address, which web features are restricted, and which keywords are blocked when content filtering is effective.

The CWMP-TR069 screen (Section 16.8 on page 180) lets you configure the WiMAX Modems auto-configuration and dynamic service configuration options. 16.1.2 What You Need to Know The following terms and concepts may help as you read through this chapter. Remote Management Limitations Remote management over LAN or WAN will not work when:
1 A filter in SMT menu 3.1 (LAN) or in menu 11.5 (WAN) is applied to block a Telnet, FTP or Web service. 2 3 4 You have disabled that service in one of the remote management screens. The IP address in the Secured Client IP field does not match the client IP address. If it does not match, the WiMAX Modem will disconnect the session immediately. There is already another remote management session with an equal or higher priority running. You may only have one remote management session running at one time. Remote Management and NAT When NAT is enabled:
Use the WiMAX Modems WAN IP address when configuring from the WAN. Use the WiMAX Modems LAN IP address when configuring from the LAN. System Timeout There is a default system management idle timeout of five minutes (three hundred seconds). The WiMAX Modem automatically logs you out if the management session remains idle for longer than this timeout period. The management session does not time out when a statistics screen is polling. You can change the timeout period in the Maintenance > System > General screen. 172 Users Guide Chapter 16The Remote Management Screens SNMP Simple Network Management Protocol (SNMP) is a protocol used for exchanging management information between network devices. SNMP is a member of the TCP/IP protocol suite. Your WiMAX Modem supports SNMP agent functionality, which allows a manager station to manage and monitor the WiMAX Modem through the network. The WiMAX Modem supports SNMP version one (SNMPv1) and version two (SNMPv2). The next figure illustrates an SNMP management operation. Note: SNMP is only available if TCP/IP is configured. 16.2 WWW Click TOOLS > Remote Management > WWW to control HTTP access to your WiMAX Modem.

Figure 79 SNMP Management Model An agent is a management software module that resides in a managed device (the WiMAX Modem). An agent translates the local management information from the managed device into a form compatible with SNMP. The manager is the console through which network administrators perform network management functions. It executes applications that control and monitor managed devices. Users Guide 175 Chapter 16The Remote Management Screens The managed devices contain object variables/managed objects that define each piece of information to be collected about a device. Examples of variables include such as number of packets received, node port status etc. A Management Information Base (MIB) is a collection of managed objects. SNMP allows a manager and agents to communicate for the purpose of accessing these objects. The WiMAX Modem supports MIB II that is defined in RFC-1213 and RFC-1215. The focus of the MIBs is to let administrators collect statistical data and monitor status and performance. SNMP itself is a simple request/response protocol based on the manager/agent model. The manager issues a request and the agent returns responses using the following protocol operations:
Get - Allows the manager to retrieve an object variable from the agent. GetNext - Allows the manager to retrieve the next object variable from a table or list within an agent. In SNMPv1, when a manager wants to retrieve all elements of a table from an agent, it initiates a Get operation, followed by a series of GetNext operations. Set - Allows the manager to set values for object variables within an agent. Trap - Used by the agent to inform the manager of some events. 16.5.1 SNMP Traps The WiMAX Modem sends traps to the SNMP manager when any of the following events occurs:
Table 67 SNMP Traps TRAP # TRAP NAME 0 coldStart (defined in RFC-
1215) warmStart (defined in RFC-
1215) authenticationFailure (defined in RFC-1215) whyReboot 1 4 6 6a For intentional reboot:
6b For fatal error:
DESCRIPTION A trap is sent after booting (power on). A trap is sent after booting (software reboot). A trap is sent to the manager when receiving any SNMP get or set requirements with the wrong community (password). A trap is sent with the reason of restart before rebooting when the system is going to restart

Select this to prevent outsiders from discovering your WiMAX Modem by sending requests to unsupported port numbers. If an outside user attempts to probe an unsupported port on your WiMAX Modem, an ICMP response packet is automatically returned. This allows the outside user to know the WiMAX Modem exists. Your WiMAX Modem supports anti-probing, which prevents the ICMP response packet from being sent. This keeps outsiders from discovering your WiMAX Modem when unsupported ports are probed. If you clear this, your WiMAX Modem replies with an ICMP Port Unreachable packet for a port probe on unused UDP ports and with a TCP Reset packet for a port probe on unused TCP ports.

It can be managed over a WAN by means of an Auto Configuration Server (ACS). TR-069 is based on sending Remote Procedure Calls
(RPCs) between the ACS and the client device. RPCs are sent in Extensible Markup Language (XML) format over HTTP or HTTPS. An administrator can use an ACS to remotely set up the WiMAX Modem, modify its settings, perform firmware upgrades, and monitor and diagnose it. In order to do so, you must enable the TR-069 feature on your WiMAX Modem and then configure it appropriately. (The ACS server which it will use must also be configured by its administrator.) Figure 83 TR-069 Example SIP ACS HTTP In this example, the WiMAX Modem receives data from at least 3 sources: A SIP server for handling voice calls, an HTTP server for handling web services, and an ACS, for configuring the WiMAX Modem remotely. All three servers are owned and operated by the clients Internet Service Provider. However, without the configuration settings from the ACS, the WiMAX Modem cannot access the other two servers. Once the WiMAX Modem receives its configuration settings and implements them, it can connect to the other servers. If the settings change, it will once again be unable to connect until it receives its updates from the ACS. The WiMAX Modem can be configured to periodically check for updates from the auto-configuration server so that the end user need not be worried about it. 180 Users Guide Chapter 16The Remote Management Screens Click TOOLS > Remote Management > CWMP-TR069 to access this screen.

Periodic Inform Enable Note: This must be provided by the ACS administrator. Select thisto allow the WiMAX Modem to periodically connect to the ACS and check for configuration updates. If you do not enable this feature then the WiMAX Modem can only be updated automatically when the ACS initiates contact with it and if you selected the Active checkbox on this screen. Enter the time interval (in seconds) at which the WiMAX Modem connects to the auto-configuration server. Enter a time interval that the WiMAX Modem will trigger a periodic inform interval. This works in tandem with the Periodic Inform Interval and is not mutually exclusive of it. The Periodic Inform Time must be in the following format: yyyy-mm-
ddThh:mm:ss where yyyy is a four digit year ( 2009), mm is a two digit month (01~12), dd is a two digit day (01~28), hh is a two-digit hour in 24-hour format (01~24), mm is a two digit minutes value (01-
60) and ss is a two digit seconds value (01-60). Note: You must separate the day information from the hour information with a T. This feature gives the WiMAX Modem abaseline from which to begin calculating when each periodic inform happens. If the inform time is set for some point in the past, the WiMAX Modem interpolates the inform interval forward to the current time and begins its periodic inform at the appropriate time based on this interpolation. If the inform time is set for some point in the future, then the WiMAX Modem interpolates backwards to the current time and actually begins at the appropriate time based on this interpolation.

Without QoS, all traffic data is equally likely to be dropped when the network is congested. This can cause a reduction in network performance and make the network inadequate for time-critical application such as video-on-
demand. 17.2 General Click TOOLS > QoS to open the screen as shown next. Use this screen to enable or disable QoS. Figure 85 QoS > General The following table describes the labels in this screen.

A classifier groups traffic into data flows according to specific criteria such as the source address, destination address, source port number, destination port number or incoming interface. For example, you can configure a classifier to select traffic from the same protocol port (such as Telnet) to form a flow. You can give different priorities to traffic that the WiMAX Modem forwards out through the WAN interface. Give high priority to voice and video to make them run more smoothly. Similarly, give low priority to many large file downloads so that they do not reduce the quality of other applications. Click TOOLS > QoS > ClassSetup to open the following screen.

For a list of log messages, see Section 18.4 on page 193. 18.1.1 What You Can Do in This Chapter The View Logs screen (Section 18.2 on page 189) lets you look at log entries and alerts. The Log Settings screen (Section 18.3 on page 191) lets you configure where the WiMAX Modem sends logs and alerts, the schedule for sending logs, and which logs and alerts are sent or recorded. 18.1.2 What You Need to Know The following terms and concepts may help as you read through this chapter. Alerts An alert is a type of log that warrants more serious attention. Some categories such as System Errors consist of both logs and alerts. Syslog Logs There are two types of syslog: event logs and traffic logs. The device generates an event log when a system event occurs, for example, when a user logs in or the device is under attack. The device generates a traffic log when a "session" is terminated. A traffic log summarizes the session's type, when it started and stopped the amount of traffic that was sent and received and so on. An external log analyzer Users Guide 187 Chapter 18The Logs Screens can reconstruct and analyze the traffic flowing through the device after collecting the traffic logs.

The severity is the logs syslog class. The definition of messages and notes are defined in the various log charts throughout this appendix. The devID is the MAC address of the routers LAN port. The cat is the same as the category in the router s logs. This message is sent by the device when the connection (session) is closed. The facility is defined in the Log Settings screen. The severity is the traffic log type. The message and note always display
"Traffic Log". The "proto" field lists the service name. The "dir" field lists the incoming and outgoing interfaces ("LAN:LAN", "LAN:WAN",
"LAN:DEV" for example). Traffic Log: <Facility*8 +

The router sent a TCP reset packet when the number of TCP incomplete connections exceeded the user configured threshold. (the TCP incomplete count is per destination host.) The router sent a TCP reset packet when a TCP connection state was out of order.Note: The firewall refers to RFC793 Figure 6 to check the TCP state. The router sent a TCP reset packet when a dynamic firewall session timed out. The default timeout values are as follows:
ICMP idle timeout: 3 minutes UDP idle timeout: 3 minutes TCP connection (three way handshaking) timeout: 270 seconds TCP FIN-wait timeout: 2 MSL (Maximum Segment Lifetime set in the TCP header). TCP idle (established) timeout (s): 150 minutes TCP reset timeout: 10 seconds The router sent a TCP reset packet when the number of incomplete connections (TCP and UDP) exceeded the user-configured threshold. (Incomplete count is for all TCP and UDP connections through the firewall.)Note:
When the number of incomplete connections (TCP + UDP)
> Maximum Incomplete High, the router sends TCP RST packets for TCP connections and destroys TOS (firewall dynamic sessions) until incomplete connections <

based management solution for the WiMAX Modem. You must connect using a compatible web browser in order to use it. The WiMAX Modem is ideal for high-speed wireless Internet browsing. WiMAX (Worldwide Interoperability for Microwave Access) is a wireless networking standard providing high-bandwidth, wide-range secured wireless service. The WiMAX Modem is a WiMAX mobile station (MS) compatible with the IEEE 802.16e standard. FirewallThe WiMAX Modem is a stateful inspection firewall with DoS
(Denial of Service) protection. By default, when the firewall is activated, all incoming traffic from the WAN to the LAN is blocked unless it is initiated from the LAN. The WiMAX Modems firewall supports TCP/UDP inspection, DoS detection and prevention, real time alerts, reports and logs. Content FilteringThe WiMAX Modem can block access to web sites containing Network Address Translation (NAT) specified keywords. You can define time periods and days during which content filtering is enabled and include or exclude a range of users on the LAN from content filtering. Network Address Translation (NAT) allows the translation of an Internet protocoladdress used within one network (for example a private IP address used in a local network) to a different IP address known withinanother network (for example a public IP address used on the Internet). Dynamic DNS SupportWith Dynamic DNS support, you can have a static hostname alias for a dynamic IP address, allowing the host to be more easily accessible from various locations on the Internet. You must register for this service with a Dynamic DNS service provider. 224 Users Guide Chapter 21Product Specifications Table 103 Firmware Specifications (continued) FEATUREDESCRIPTION DHCPDHCP (Dynamic Host Configuration Protocol) allows the individual clients (computers) to obtain the TCP/IP configuration at start-up from a centralized DHCP server. Your device has built-in DHCP server capability enabled by default. It can assign IP addresses, an IP default gateway and DNS servers to DHCP clients. IP AliasIP alias allows you to partition a physical network into logical networks over the same Ethernet interface. Your device supports three logical LAN interfaces via its single physical Ethernet interface with the your device itself as the gateway for each LAN network. Multiple SIP AccountsYou can configure multiple voice (SIP) accounts. SIP ALGYour device is a SIP Application Layer Gateway (ALG). It allows VoIP calls to pass through NAT for devices behind it
(such as a SIP-based VoIP software application on a computer). Dynamic Jitter BufferThe built-in adaptive buffer helps to smooth out the variations in delay (jitter) for voice traffic (up to 60 ms). This helps ensure good voice quality for your conversations. Voice Activity Detection/
Voice Activity Detection (VAD) reduces the bandwidth that a Silence Suppression call uses by not transmitting when you are not speaking. Comfort Noise GenerationYour device generates background noise to fill moments of silence when the other device in a call stops transmitting because the other party is not speaking (as total silence could easily be mistaken for a lost connection). Echo Cancellation You device supports G.168 of at least 24 ms. This an ITU-T standard for eliminating the echo caused by the sound of your voice reverberating in the telephone receiver while you talk.

The caller must still pay while the call is parked. When you park the call, you enter a number of your choice (up to eight digits), which you must enter again when you pick up the call. If you do not enter the correct number, you cannot pickup the call. This means that only someone who knows the number you have chosen can pick up the call. You can have more than one call on hold at the same time, but you must give each call a different number. Call ReturnWith call return, you can place a call to the last number that called you (either answered or missed). The last incoming call can be through either SIP or PSTN. Country CodePhone standards and settings differ from one country to another, so the settings on your WiMAX Modem must be configured to match those of the country you are in. The country code feature allows you to do this by selecting the country from a list rather than changing each setting manually. Configure the country code feature when you move the WiMAX Modem from one country to another. This feature allows you to set your phone not to ring when someone calls you. You can set each phone independently using its keypad, or configure global settings for all phones using the command line interpreter. Do not Disturb
(DnD) Auto DialYou can set the WiMAX Modem to automatically dial a specified number immediately whenever you lift a phone off the hook. Use the Web Configurator to set the specified number. Use the command line interpreter to have the WiMAX Modem wait a specified length of time before dialing the number. Phone configThe phone configuration table allows you to customize the phone Firmware update enable / disable keypad combinations you use to access certain features on the WiMAX Modem, such as call waiting, call return, call forward, etc. The phone configuration table is configurable in command interpreter mode. If your service provider uses this feature, you hear a recorded message when you pick up the phone when new firmware is available for your WiMAX Modem. Enter *99# in your phones keypad to have the WiMAX Modem upgrade the firmware, or enter #99# to not upgrade. If your service provider gave you different numbers to use, enter them instead. If you enter the code to not upgrade, you can make a call as normal. You will hear the recording again each time you pick up the phone, until you upgrade. Users Guide 227 Chapter 21Product Specifications Table 105 Voice Features Call waitingThis feature allows you to hear an alert when you are already using the phone and another person calls you. You can then either reject the new incoming call, put your current call on hold and receive the new incoming call, or end the current call and receive the new incoming call. Call forwardingWith this feature, you can set the WiMAX Modem to forward calls to a specified number, either unconditionally (always), when your number is busy, or when you do not answer. You can also forward incoming calls from one specified number to another. Caller IDThe WiMAX Modem supports caller ID, which allows you to see the originating number of an incoming call (on a phone with a suitable display). RENA Ringer Equivalence Number (REN) is used to determine the number QoS (Quality of Service) of devices (like telephones or fax machines) that may be connected to the telephone line. Your device has a REN of three, so it can support three devices per telephone port. Quality of Service (QoS) mechanisms help to provide better service on a per-flow basis. Your device supports Type of Service (ToS) tagging and Differentiated Services (DiffServ) tagging. This allows the device to tag voice frames so they can be prioritized over the network.

Users Guide 229 Chapter 21Product Specifications 230 Users Guide APPENDIX A WiMAX Security Wireless security is vital to protect your wireless communications. Without it, information transmitted over the wireless network would be accessible to any networking device within range. User Authentication and Data Encryption The WiMAX (IEEE 802.16) standard employs user authentication and encryption to ensure secured communication at all times. User authentication is the process of confirming a users identity and level of authorization. Data encryption is the process of encoding information so that it cannot be read by anyone who does not know the code. WiMAX uses PKMv2 (Privacy Key Management version 2) for authentication, and CCMP (Counter Mode with Cipher Block Chaining Message Authentication Protocol) for data encryption. WiMAX supports EAP (Extensible Authentication Protocol, RFC 2486) which allows additional authentication methods to be deployed with no changes to the base station or the mobile or subscriber stations. PKMv2 is a procedure that allows authentication of a mobile or subscriber station and negotiation of a public key to encrypt traffic between the MS/SS and the base station. PKMv2 uses standard EAP methods such as Transport Layer Security
(EAP-TLS) or Tunneled TLS (EAP-TTLS) for secure communication. In cryptography, a key is a piece of information, typically a string of random numbers and letters, that can be used to lock (encrypt) or unlock (decrypt) a message. Public key encryption uses key pairs, which consist of a public (freely available) key and a private (secret) key. The public key is used for encryption and the private key is used for decryption. You can decrypt a message only if you have the private key. Public key certificates (or digital IDs) allow users to verify each others identity. PKMv2 Users Guide 231 Appendix AWiMAX Security RADIUS RADIUS is based on a client-server model that supports authentication, authorization and accounting. The base station is the client and the server is the RADIUS server. The RADIUS server handles the following tasks:
Authentication Determines the identity of the users. Authorization Determines the network services available to authenticated users once they are connected to the network. Accounting Keeps track of the clients network activity. RADIUS is a simple package exchange in which your base station acts as a message relay between the MS/SS and the network RADIUS server. Types of RADIUS Messages The following types of RADIUS messages are exchanged between the base station and the RADIUS server for user authentication:
Access-Request Sent by an base station requesting authentication. Access-Reject Sent by a RADIUS server rejecting access. Access-Accept Sent by a RADIUS server allowing access. Access-Challenge Sent by a RADIUS server requesting more information in order to allow access. The base station sends a proper response from the user and then sends another Access-Request message. The following types of RADIUS messages are exchanged between the base station and the RADIUS server for user accounting:
Accounting-Request Sent by the base station requesting accounting. Accounting-Response Sent by the RADIUS server to indicate that it has started or stopped accounting. In order to ensure network security, the access point and the RADIUS server use a shared secret key, which is a password they both know. The key is not sent over 232 Users Guide the network. In addition to the shared key, password information exchanged is also encrypted to protect the network from unauthorized access. Appendix AWiMAX Security Diameter Diameter (RFC 3588) is a type of AAA server that provides several improvements over RADIUS in efficiency, security, and support for roaming. Security Association CCMP The set of information about user authentication and data encryption between two computers is known as a security association (SA). In a WiMAX network, the process of security association has three stages. Authorization request and reply The MS/SS presents its public certificate to the base station. The base station verifies the certificate and sends an authentication key (AK) to the MS/SS. Key request and reply The MS/SS requests a transport encryption key (TEK) which the base station generates and encrypts using the authentication key. Encrypted traffic The MS/SS decrypts the TEK (using the authentication key). Both stations can now securely encrypt and decrypt the data flow. All traffic in a WiMAX network is encrypted using CCMP (Counter Mode with Cipher Block Chaining Message Authentication Protocol). CCMP is based on the 128-bit Advanced Encryption Standard (AES) algorithm. Counter mode refers to the encryption of each block of plain text with an arbitrary number, known as the counter. This number changes each time a block of plain text is encrypted. Counter mode avoids the security weakness of repeated identical blocks of encrypted text that makes encrypted data vulnerable to pattern-spotting. Cipher Block Chaining Message Authentication (also known as CBC-MAC) ensures message integrity by encrypting each block of plain text in such a way that its encryption is dependent on the block before it. This series of chained blocks creates a message authentication code (MAC or CMAC) that ensures the encrypted data has not been tampered with. Users Guide 233 Appendix AWiMAX Security Authentication The WiMAX Modem supports EAP-TTLS authentication. EAP-TTLS (Tunneled Transport Layer Service) EAP-TTLS is an extension of the EAP-TLS authentication that uses certificates for only the server-side authentications to establish a secure connection (with EAP-
TLS digital certifications are needed by both the server and the wireless clients for mutual authentication). Client authentication is then done by sending username and password through the secure connection, thus client identity is protected. For client authentication, EAP-TTLS supports EAP methods and legacy authentication methods such as PAP, CHAP, MS-CHAP and MS-CHAP v2. 234 Users Guide APPENDIX B Setting Up Your Computers IP Address Note: Your specific device may not support all of the operating systems described in this appendix.

IP addresses identify individual devices on a network. Every networking device
(including computers, servers, routers, printers, etc.) needs an IP address to communicate across the network. These networking devices are also known as hosts. Subnet masks determine the maximum number of possible hosts on a network. You can also use subnet masks to divide one network into multiple sub-networks. Introduction to IP Addresses One part of the IP address is the network number, and the other part is the host ID. In the same way that houses on a street share a common street name, the hosts on a network share a common network number. Similarly, as each house has its own house number, each host on the network has its own unique identifying number - the host ID. Routers use the network number to send packets to the correct network, while the host ID determines to which host on the network the packets are delivered. Structure An IP address is made up of four parts, written in dotted decimal notation (for example, 192.168.1.1). Each of these four parts is known as an octet. An octet is an eight-digit binary number (for example 11000000, which is 192 in decimal notation). Therefore, each octet has a possible range of 00000000 to 11111111 in binary, or 0 to 255 in decimal. Users Guide 273 Appendix DIP Addresses and Subnetting The following figure shows an example IP address in which the first three octets
(192.168.1) are the network number, and the fourth octet (16) is the host ID. Figure 146 Network Number and Host ID How much of the IP address is the network number and how much is the host ID varies according to the subnet mask. Subnet Masks A subnet mask is used to determine which bits are part of the network number, and which bits are part of the host ID (using a logical AND operation). The term subnet is short for sub-network. A subnet mask has 32 bits. If a bit in the subnet mask is a 1 then the corresponding bit in the IP address is part of the network number. If a bit in the subnet mask is 0 then the corresponding bit in the IP address is part of the host ID. The following example shows a subnet mask identifying the network number (in bold text) and host ID of an IP address (192.168.1.2 in decimal).

Subnet masks can be referred to by the size of the network number part (the bits with a 1 value). For example, an 8-bit mask means that the first 8 bits of the mask are ones and the remaining 24 bits are zeroes. Subnet masks are expressed in dotted decimal notation just like IP addresses. The following examples show the binary and decimal notation for 8-bit, 16-bit, 24-bit and 29-bit subnet masks.

The larger the number of network number bits, the smaller the number of remaining host ID bits. An IP address with host IDs of all zeros is the IP address of the network
(192.168.1.0 with a 24-bit subnet mask, for example). An IP address with host IDs of all ones is the broadcast address for that network (192.168.1.255 with a 24-bit subnet mask, for example). As these two IP addresses cannot be used for individual hosts, calculate the maximum number of possible hosts in a network as follows:

This is usually specified by writing a / followed by the number of bits in the mask after the address. For example, 192.1.1.0 /25 is equivalent to saying 192.1.1.0 with subnet mask 255.255.255.128.

In the following example a network administrator creates two sub-networks to isolate a group of servers from the rest of the company network for security reasons. In this example, the company network address is 192.168.1.0. The first three octets of the address (192.168.1) are the network number, and the remaining octet is the host ID, allowing a maximum of 28 2 or 254 possible hosts. 276 Users Guide Appendix DIP Addresses and Subnetting The following figure shows the company network before subnetting. Figure 147 Subnetting Example: Before Subnetting You can borrow one of the host ID bits to divide the network 192.168.1.0 into two separate sub-networks. The subnet mask is now 25 bits (255.255.255.128 or
/25). The borrowed host ID bit can have a value of either 0 or 1, allowing two subnets; 192.168.1.0 /25 and 192.168.1.128 /25. Users Guide 277 Appendix DIP Addresses and Subnetting The following figure shows the company network after subnetting. There are now two sub-networks, A and B. Figure 148 Subnetting Example: After Subnetting In a 25-bit subnet the host ID has 7 bits, so each sub-network has a maximum of 27 2 or 126 possible hosts (a host ID of all zeroes is the subnets address itself, all ones is the subnets broadcast address). 192.168.1.0 with mask 255.255.255.128 is subnet A itself, and 192.168.1.127 with mask 255.255.255.128 is its broadcast address. Therefore, the lowest IP address that can be assigned to an actual host for subnet A is 192.168.1.1 and the highest is 192.168.1.126. Similarly, the host ID range for subnet B is 192.168.1.129 to 192.168.1.254. Example: Four Subnets The previous example illustrated using a 25-bit subnet mask to divide a 24-bit address into two subnets. Similarly, to divide a 24-bit address into four subnets, you need to borrow two host ID bits to give four possible combinations (00, 01, 10 and 11). The subnet mask is 26 bits
(11111111.11111111.11111111.11000000) or 255.255.255.192. 278 Users Guide Appendix DIP Addresses and Subnetting Each subnet contains 6 host ID bits, giving 26 - 2 or 62 hosts for each subnet (a host ID of all zeroes is the subnet itself, all ones is the subnets broadcast address).

If the ISP or your network administrator assigns you a block of registered IP addresses, follow their instructions in selecting the IP addresses and the subnet mask. If the ISP did not explicitly give you an IP network number, then most likely you have a single user account and the ISP will assign you a dynamic IP address when the connection is established. If this is the case, it is recommended that you select a network number from 192.168.0.0 to 192.168.255.0. The Internet Assigned Number Authority (IANA) reserved this block of addresses specifically for private use; please do not use any other number unless you are told otherwise. You must also enable Network Address Translation (NAT) on the WiMAX Modem. Once you have decided on the network number, pick an IP address for your WiMAX Modem that is easy to remember (for instance, 192.168.1.1) but make sure that no other device on your network is using that IP address. The subnet mask specifies the network number portion of an IP address. Your WiMAX Modem will compute the subnet mask automatically based on the IP Users Guide 281 Appendix DIP Addresses and Subnetting address that you entered. You don't need to change the subnet mask computed by the WiMAX Modem unless you are instructed to do otherwise. Private IP Addresses Every machine on the Internet must have a unique address. If your networks are isolated from the Internet (running only between two branch offices, for example) you can assign any IP addresses to the hosts without problems. However, the Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of IP addresses specifically for private networks:
10.0.0.0 10.255.255.255 172.16.0.0 172.31.255.255 192.168.0.0 192.168.255.255 You can obtain your IP address from the IANA, from an ISP, or it can be assigned from a private network. If you belong to a small organization and your Internet access is through an ISP, the ISP can provide you with the Internet addresses for your local networks. On the other hand, if you are part of a much larger organization, you should consult your network administrator for the appropriate IP addresses. Regardless of your particular situation, do not create an arbitrary IP address;
always follow the guidelines above. For more information on address assignment, please refer to RFC 1597, Address Allocation for Private Internets and RFC 1466, Guidelines for Management of IP Address Space. IP Address Conflicts Each device on a network must have a unique IP address. Devices with duplicate IP addresses on the same network will not be able to access the Internet or other resources. The devices may also be unreachable through the network. Conflicting Computer IP Addresses Example More than one device can not use the same IP address. In the following example computer A has a static (or fixed) IP address that is the same as the IP address that a DHCP server assigns to computer B which is a DHCP client. Neither can access the Internet. This problem can be solved by assigning a different static IP 282 Users Guide Appendix DIP Addresses and Subnetting address to computer A or setting computer A to obtain an IP address automatically. Figure 149 Conflicting Computer IP Addresses Example Conflicting Router IP Addresses Example Since a router connects different networks, it must have interfaces using different network numbers. For example, if a router is set between a LAN and the Internet
(WAN), the routers LAN and WAN addresses must be on different subnets. In the following example, the LAN and WAN are on the same subnet. The LAN computers cannot access the Internet because the router cannot route between networks. Figure 150 Conflicting Computer IP Addresses Example Conflicting Computer and Router IP Addresses Example More than one device can not use the same IP address. In the following example, the computer and the routers LAN port both use 192.168.1.1 as the IP address. Users Guide 283 Appendix DIP Addresses and Subnetting The computer cannot access the Internet. This problem can be solved by assigning a different IP address to the computer or the routers LAN port.

If you want to use STUN with a SIP client device (a SIP phone or IP phone for example) behind the WiMAX Modem, use the ip alg disable ALG_SIP command to turn off the SIP ALG. Signaling Session Timeout Most SIP clients have an expire mechanism indicating the lifetime of signaling sessions. The SIP UA sends registration packets to the SIP server periodically and keeps the session alive in the WiMAX Modem. If the SIP client does not have this mechanism and makes no call during the WiMAX Modem SIP timeout default (60 minutes), the WiMAX Modem SIP ALG drops any incoming calls after the timeout period. You can use the ip alg siptimeout command to change the timeout value. Audio Session Timeout If no voice packets go through the SIP ALG before the timeout period default (5 minutes) expires, the SIP ALG does not drop the call but blocks all voice traffic and deletes the audio session. You cannot hear anything and you will need to make a new call to continue your conversation.
