The wireless clients can access the Internet through an AP wirelessly. 2.1 Example Parameters SSID Channel Security 802.11 mode SSID_Example3 6 WPA-PSK

(Pre-Shared Key: ThisismyWPA-PSKpre-sharedkey) IEEE 802.11b/g An access point (AP) or wireless router is referred to as an AP and a computer with a wireless network card or USB/PCI adapter is referred to as a wireless client here. We use the M-302 utility screens as an example for the wireless client. The screens may vary for different models. 2.2 Configuring the AP Flow the steps below to configure the wireless settings on your AP. 1 Open the Wireless LAN > General screen in the APs web configurator. ZyXEL NBG-334SH Users Guide 33 Chapter 2 Wireless Tutorial Figure 4 AP: Wireless LAN > General 2 Make sure the Enable Wireless LAN check box is selected. 3 Enter SSID_Example3 as the SSID and select a channel. 4 Set security mode to WPA-PSK and enter ThisismyWPA-PSKpre-sharedkey in the Pre-Shared Key field. Click Apply. 5 Open the Status screen.Verify your wireless and wireless security settings under Device Information and check if the WLAN connection is up under Interface Status. 34 ZyXEL NBG-334SH Users Guide Figure 5 AP: Status Chapter 2 Wireless Tutorial 6 Click the WLAN Station Status hyperlink in the APs Status screen. You can see if any wireless client has connected to the AP. Figure 6 AP: Status: WLAN Station Status 2.3 Configuring the Wireless Client This section describes how to connect the wireless client to a network. ZyXEL NBG-334SH Users Guide 35 Chapter 2 Wireless Tutorial 2.3.1 Connecting to a Wireless LAN The following sections show you how to join a wireless network using the ZyXEL utility, as in the following diagram. The wireless client is labeled C and the access point is labeled AP. There are three ways to connect the client to an access point. Configure nothing and leave the wireless client to automatically scan for and connect to any available network that has no wireless security configured. Manually connect to a network. Configure a profile to have the wireless client automatically connect to a specific network or peer computer. This example illustrates how to manually connect your wireless client to an access point (AP) which is configured for WPA-PSK security and connected to the Internet. Before you connect to the access point, you must know its Service Set IDentity (SSID) and WPA-PSK pre-shared key. In this example, the SSID is SSID_Example3 and the pre-shared key is ThisismyWPA-PSKpre-sharedkey. After you install the ZyXEL utility and then insert the wireless client, follow the steps below to connect to a network using the Site Survey screen. 1 Open the ZyXEL utility and click the Site Survey tab to open the screen shown next. 2 The wireless client automatically searches for available wireless networks. Click Scan if you want to search again. If no entry displays in the Available Network List, that means there is no wireless network available within range. Make sure the AP or peer computer is turned on or move the wireless client closer to the AP or peer computer. 3 When you try to connect to an AP with security configured, a window will pop up prompting you to specify the security settings. Enter the pre-shared key and leave the encryption type at the default setting. Use the Next button to move on to the next screen. You can use the Back button at any time to return to the previous screen, or the Exit button to return to the Site Survey screen. 36 ZyXEL NBG-334SH Users Guide Figure 7 ZyXEL Utility: Security Settings Chapter 2 Wireless Tutorial 4 The Confirm Save window appears.

PPTP 4.4.1 Ethernet Connection Choose Ethernet when the WAN port is used as a regular Ethernet. Figure 32 Wizard Step 3: Ethernet Connection 4.4.2 PPPoE Connection Point-to-Point Protocol over Ethernet (PPPoE) functions as a dial-up connection. PPPoE is an IETF (Internet Engineering Task Force) standard specifying how a host personal computer interacts with a broadband modem (for example DSL, cable, wireless, etc.) to achieve access to high-speed data networks. For the service provider, PPPoE offers an access and authentication method that works with existing access control systems (for instance, RADIUS). ZyXEL NBG-334SH Users Guide 61 Chapter 4 Connection Wizard One of the benefits of PPPoE is the ability to let end users access one of multiple network services, a function known as dynamic service selection. This enables the service provider to easily create and offer new IP services for specific users. Operationally, PPPoE saves significant effort for both the subscriber and the ISP/carrier, as it requires no specific configuration of the broadband modem at the subscribers site. By implementing PPPoE directly on the ZyXEL Device (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the ZyXEL Device does that part of the task. Furthermore, with NAT, all of the LAN's computers will have Internet access. Refer to the appendix for more information on PPPoE. Figure 33 Wizard Step 3: PPPoE Connection The following table describes the labels in this screen.

Click Exit to close the wizard screen without saving. Use fixed IP address provided by your ISP Back Next Exit 4.4.5 WAN IP Address Assignment Every computer on the Internet must have a unique IP address. If your networks are isolated from the Internet, for instance, only between your two branch offices, 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. Table 16 Private IP Address Ranges 10.0.0.0 172.16.0.0 192.168.0.0 10.255.255.255 172.31.255.255 192.168.255.255

64 ZyXEL NBG-334SH Users Guide Chapter 4 Connection Wizard You can obtain your IP address from the IANA, from an ISP or have it assigned by 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. 4.4.6 IP Address and Subnet Mask Similar to the way houses on a street share a common street name, so too do computers on a LAN share one common network number. 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. 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 ZyXEL Device, 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 ZyXEL Device 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 ZyXEL Device unless you are instructed to do otherwise. 4.4.7 DNS Server Address Assignment Use DNS (Domain Name System) to map a domain name to its corresponding IP address and vice versa, for instance, the IP address of www.zyxel.com is 204.217.0.2. The DNS server is extremely important because without it, you must know the IP address of a computer before you can access it. The ZyXEL Device can get the DNS server addresses in the following ways. 1 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 Wizard and/or WAN > Internet Connection screen. ZyXEL NBG-334SH Users Guide 65 Chapter 4 Connection Wizard 2 If the ISP did not give you DNS server information, leave the DNS Server fields set to 0.0.0.0 in the Wizard screen and/or set to From ISP in the WAN > Internet Connection screen for the ISP to dynamically assign the DNS server IP addresses. 4.4.8 WAN IP and DNS Server Address Assignment The following wizard screen allows you to assign a fixed WAN IP address and DNS server addresses. Figure 36 Wizard Step 3: WAN IP and DNS Server Addresses The following table describes the labels in this screen Table 17 Wizard Step 3: WAN IP and DNS Server Addresses LABEL WAN IP Address Assignment My WAN IP Address DESCRIPTION Enter your WAN IP address in this field. The WAN IP address should be in the same subnet as your DSL/Cable modem or router. Enter the gateway IP address in this field. My WAN IP Subnet Mask Enter the IP subnet mask in this field. Gateway IP Address System DNS Server Address Assignment (if applicable) 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 computer before you can access it. The ZyXEL Device uses a system DNS server (in the order you specify here) to resolve domain names for DDNS and the time server. First DNS Server Second DNS Server Third DNS Server Back Next Exit Enter the DNS server's IP address in the fields provided. If you do not configure a system DNS server, you must use IP addresses when configuring DDNS and the time server. Click Back to return to the previous screen. Click Next to continue.

See the appendices for more detailed information about wireless networks. 5.1 Wireless Network Overview The following figure provides an example of a wireless network. Figure 41 Example of a Wireless Network The wireless network is the part in the blue circle. In this wireless network, devices A and B are called wireless clients. The wireless clients use the access point (AP) to interact with other devices (such as the printer) or with the Internet. Your ZyXEL Device is the AP. Every wireless network must follow these basic guidelines. Every wireless client in the same wireless network must use the same SSID. The SSID is the name of the wireless network. It stands for Service Set IDentity. If two wireless networks overlap, they should use different channels. Like radio stations or television channels, each wireless network uses a specific channel, or frequency, to send and receive information. ZyXEL NBG-334SH Users Guide 73 Chapter 5 Wireless LAN Every wireless client in the same wireless network must use security compatible with the AP. Security stops unauthorized devices from using the wireless network. It can also protect the information that is sent in the wireless network. 5.2 Wireless Security Overview The following sections introduce different types of wireless security you can set up in the wireless network. 5.2.1 SSID Normally, the AP acts like a beacon and regularly broadcasts the SSID in the area. You can hide the SSID instead, in which case the AP does not broadcast the SSID. In addition, you should change the default SSID to something that is difficult to guess. This type of security is fairly weak, however, because there are ways for unauthorized devices to get the SSID. In addition, unauthorized devices can still see the information that is sent in the wireless network. 5.2.2 MAC Address Filter Every wireless client has a unique identification number, called a MAC address.1 A MAC address is usually written using twelve hexadecimal characters2; for example, 00A0C5000002 or 00:A0:C5:00:00:02. To get the MAC address for each wireless client, see the appropriate Users Guide or other documentation. You can use the MAC address filter to tell the AP which wireless clients are allowed or not allowed to use the wireless network. If a wireless client is allowed to use the wireless network, it still has to have the correct settings (SSID, channel, and security). If a wireless client is not allowed to use the wireless network, it does not matter if it has the correct settings. This type of security does not protect the information that is sent in the wireless network. Furthermore, there are ways for unauthorized devices to get the MAC address of an authorized wireless client. Then, they can use that MAC address to use the wireless network. 5.2.3 User Authentication You can make every user log in to the wireless network before they can use it. This is called user authentication. However, every wireless client in the wireless network has to support IEEE 802.1x to do this. For wireless networks, there are two typical places to store the user names and passwords for each user. In the AP: this feature is called a local user database or a local database. In a RADIUS server: this is a server used in businesses more than in homes. 1. Some wireless devices, such as scanners, can detect wireless networks but cannot use wireless networks. These kinds of wireless devices might not have MAC addresses. 2. Hexadecimal characters are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F. 74 ZyXEL NBG-334SH Users Guide Chapter 5 Wireless LAN If your AP does not provide a local user database and if you do not have a RADIUS server, you cannot set up user names and passwords for your users. Unauthorized devices can still see the information that is sent in the wireless network, even if they cannot use the wireless network. Furthermore, there are ways for unauthorized wireless users to get a valid user name and password. Then, they can use that user name and password to use the wireless network. Local user databases also have an additional limitation that is explained in the next section. 5.2.4 Encryption Wireless networks can use encryption to protect the information that is sent in the wireless network. Encryption is like a secret code. If you do not know the secret code, you cannot understand the message. The types of encryption you can choose depend on the type of user authentication. (See Section 5.2.3 on page 74 for information about this.) Table 21 Types of Encryption for Each Type of Authentication Weakest NO AUTHENTICATION No Security Static WEP WPA-PSK Strongest WPA2-PSK RADIUS SERVER WPA WPA2 For example, if the wireless network has a RADIUS server, you can choose WPA or WPA2. If users do not log in to the wireless network, you can choose no encryption, Static WEP, WPA-PSK, or WPA2-PSK. Usually, you should set up the strongest encryption that every wireless client in the wireless network supports. For example, suppose the AP does not have a local user database, and you do not have a RADIUS server. Therefore, there is no user authentication. Suppose the wireless network has two wireless clients. Device A only supports WEP, and device B supports WEP and WPA. Therefore, you should set up Static WEP in the wireless network.

It is recommended that wireless networks use WPA-PSK, WPA, or stronger encryption. IEEE 802.1x and WEP encryption are better than none at all, but it is still possible for unauthorized devices to figure out the original information pretty quickly. It is not possible to use WPA-PSK, WPA or stronger encryption with a local user database. In this case, it is better to set up stronger encryption with no authentication than to set up weaker encryption with the local user database. ZyXEL NBG-334SH Users Guide 75 Chapter 5 Wireless LAN When you select WPA2 or WPA2-PSK in your ZyXEL Device, you can also select an option

(WPA Compatible) to support WPA as well. In this case, if some wireless clients support WPA and some support WPA2, you should set up WPA2-PSK or WPA2 (depending on the type of wireless network login) and select the WPA Compatible option in the ZyXEL Device. Many types of encryption use a key to protect the information in the wireless network. The longer the key, the stronger the encryption. Every wireless client in the wireless network must have the same key. 5.3 Quality of Service This section discusses the Quality of Service (QoS) features available on the ZyXEL Device. 5.3.1 WMM QoS WMM (Wi-Fi MultiMedia) QoS (Quality of Service) ensures quality of service in wireless networks. It controls WLAN transmission priority on packets to be transmitted over the wireless network. WMM QoS prioritizes wireless traffic according to delivery requirements. WMM QoS is a part of the IEEE 802.11e QoS enhancement to certified Wi-Fi wireless networks. On APs without WMM QoS, all traffic streams are given the same access priority to the wireless network. If the introduction of another traffic stream creates a data transmission demand that exceeds the current network capacity, then the new traffic stream reduces the throughput of the other traffic streams. The ZyXEL Device uses WMM QoS to prioritize traffic streams according to the IEEE 802.1q tag or DSCP information in each packets header. The ZyXEL Device automatically determines the priority to use for an individual traffic stream. This prevents reductions in data transmission for applications that are sensitive to latency (delay) and jitter (variations in delay). 5.3.1.1 WMM QoS Priorities The following table describes the WMM QoS priority levels that the ZyXEL Device uses. Table 22 WMM QoS Priorities PRIORITY LEVEL voice

(WMM_VOICE) video

(WMM_VIDEO) best effort

(WMM_BEST_EFFORT) DESCRIPTION Typically used for traffic that is especially sensitive to jitter. Use this priority to reduce latency for improved voice quality. Typically used for traffic which has some tolerance for jitter but needs to be prioritized over other data traffic. Typically used for traffic from applications or devices that lack QoS capabilities. Use best effort priority for traffic that is less sensitive to latency, but is affected by long delays, such as Internet surfing. This is typically used for non-critical traffic such as bulk transfers and print jobs that are allowed but that should not affect other applications and users. Use background priority for applications that do not have strict latency and throughput requirements. background

Choose Factory Default to select the factory assigned default MAC Address. Otherwise, click Clone the computer's MAC address - IP Address and enter the IP address of the computer on the LAN whose MAC you are cloning. Once it is successfully configured, the address will be copied to the rom file (ZyNOS configuration file). It will not change unless you change the setting or upload a different ROM file. It is recommended that you clone the MAC address prior to hooking up the WAN Port. 6.3 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. ZyXEL NBG-334SH Users Guide 89 Chapter 6 WAN The ZyXEL Device supports both IGMP version 1 (IGMP-v1) and IGMP version 2 (IGMP-

PPPoE is an IETF standard (RFC 2516) specifying how a personal computer (PC) interacts with a broadband modem (DSL, cable, wireless, etc.) connection. The PPP over Ethernet option is for a dial-up connection using PPPoE. For the service provider, PPPoE offers an access and authentication method that works with existing access control systems (for example Radius). One of the benefits of PPPoE is the ability to let you access one of multiple network services, a function known as dynamic service selection. This enables the service provider to easily create and offer new IP services for individuals. Operationally, PPPoE saves significant effort for both you and the ISP or carrier, as it requires no specific configuration of the broadband modem at the customer site. By implementing PPPoE directly on the ZyXEL Device (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the ZyXEL Device does that part of the task. Furthermore, with NAT, all of the LANs computers will have access. This screen displays when you select PPPoE encapsulation. 92 ZyXEL NBG-334SH Users Guide Figure 52 PPPoE Encapsulation Chapter 6 WAN The following table describes the labels in this screen.

A LAN is a computer network limited to the immediate area, usually the same building or floor of a building. The LAN screens can help you configure a LAN DHCP server, manage IP addresses, and partition your physical network into logical networks. 7.1.1 IP Pool Setup The ZyXEL Device is pre-configured with a pool of 32 IP addresses starting from 192.168.1.33 to 192.168.1.64. This configuration leaves 31 IP addresses (excluding the ZyXEL Device itself) in the lower range (192.168.1.2 to 192.168.1.32) for other server computers, for instance, servers for mail, FTP, TFTP, web, etc., that you may have. 7.1.2 System DNS Servers Refer to the IP address and subnet mask section in the Connection Wizard chapter. 7.2 LAN TCP/IP The ZyXEL Device has built-in DHCP server capability that assigns IP addresses and DNS servers to systems that support DHCP client capability. 7.2.1 Factory LAN Defaults The LAN parameters of the ZyXEL Device are preset in the factory with the following values:

IP address of 192.168.1.1 with subnet mask of 255.255.255.0 (24 bits) DHCP server enabled with 32 client IP addresses starting from 192.168.1.33. These parameters should work for the majority of installations. If your ISP gives you explicit DNS server address(es), read the embedded web configurator help regarding what fields need to be configured. ZyXEL NBG-334SH Users Guide 99 Chapter 7 LAN 7.2.2 IP Address and Subnet Mask Refer to the IP address and subnet mask section in the Connection Wizard chapter for this information. 7.2.3 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 ZyXEL Device supports both IGMP version 1 (IGMP-v1) and IGMP version 2 (IGMP-

v2). At start up, the ZyXEL Device queries all directly connected networks to gather group membership. After that, the ZyXEL Device periodically updates this information. IP multicasting can be enabled/disabled on the ZyXEL Device LAN and/or WAN interfaces in the web configurator (LAN; WAN). Select None to disable IP multicasting on these interfaces. 7.2.4 Any IP Traditionally, you must set the IP addresses and the subnet masks of a computer and the ZyXEL Device to be in the same subnet to allow the computer to access the Internet (through the ZyXEL Device). In cases where your computer is required to use a static IP address in another network, you may need to manually configure the network settings of the computer every time you want to access the Internet via the ZyXEL Device. With the Any IP feature and NAT enabled, the ZyXEL Device allows a computer to access the Internet without changing the network settings (such as IP address and subnet mask) of the computer, when the IP addresses of the computer and the ZyXEL Device are not in the same subnet. Whether a computer is set to use a dynamic or static (fixed) IP address, you can simply connect the computer to the ZyXEL Device and access the Internet. The following figure depicts a scenario where a computer is set to use a static private IP address in the corporate environment. In a residential house where a ZyXEL Device is installed, you can still use the computer to access the Internet without changing the network settings, even when the IP addresses of the computer and the ZyXEL Device are not in the same subnet. 100 ZyXEL NBG-334SH Users Guide

 

 

Figure 55 Any IP Example Chapter 7 LAN The Any IP feature does not apply to a computer using either a dynamic IP address or a static IP address that is in the same subnet as the ZyXEL Devices IP address.

You must enable NAT to use the Any IP feature on the ZyXEL Device. Address Resolution Protocol (ARP) is a protocol for mapping an Internet Protocol address (IP address) to a physical machine address, also known as a Media Access Control or MAC address, on the local area network. IP routing table is defined on IP Ethernet devices (the ZyXEL Device) to decide which hop to use, to help forward data along to its specified destination. The following lists out the steps taken, when a computer tries to access the Internet for the first time through the ZyXEL Device. 1 When a computer (which is in a different subnet) first attempts to access the Internet, it sends packets to its default gateway (which is not the ZyXEL Device) by looking at the MAC address in its ARP table. 2 When the computer cannot locate the default gateway, an ARP request is broadcast on the LAN. MAC address. 3 The ZyXEL Device receives the ARP request and replies to the computer with its own 4 The computer updates the MAC address for the default gateway to the ARP table. Once the ARP table is updated, the computer is able to access the Internet through the ZyXEL Device. 5 When the ZyXEL Device receives packets from the computer, it creates an entry in the IP routing table so it can properly forward packets intended for the computer. After all the routing information is updated, the computer can access the ZyXEL Device and the Internet as if it is in the same subnet as the ZyXEL Device.

(NAT) This chapter discusses how to configure NAT on the ZyXEL Device. 9.1 NAT Overview NAT (Network Address Translation - NAT, RFC 1631) is the translation of the IP address of a host in a packet. For example, the source address of an outgoing packet, used within one network is changed to a different IP address known within another network. 9.2 Using NAT

You must create a firewall rule in addition to setting up NAT, to allow traffic from the WAN to be forwarded through the ZyXEL Device. 9.2.1 Port Forwarding: Services and Port Numbers A port forwarding set is a list of inside (behind NAT on the LAN) servers, for example, web or FTP, that you can make accessible to the outside world even though NAT makes your whole inside network appear as a single machine to the outside world. Use the Application 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. ZyXEL NBG-334SH Users Guide 109 Chapter 9 Network Address Translation (NAT)

Many residential broadband ISP accounts do not allow you to run any server processes (such as a Web or FTP server) from your location. Your ISP may periodically check for servers and may suspend your account if it discovers any active services at your location. If you are unsure, refer to your ISP. 9.2.2 Configuring Servers Behind Port Forwarding Example Let's say you want to assign ports 21-25 to one FTP, Telnet and SMTP server (A in the example), port 80 to another (B in the example) and assign a default server IP address of 192.168.1.35 to a third (C in the example). You assign the LAN IP addresses and the ISP assigns the WAN IP address. The NAT network appears as a single host on the Internet Figure 62 Multiple Servers Behind NAT Example 9.3 General NAT Screen Click Network > NAT to open the General screen. Figure 63 NAT General 110 ZyXEL NBG-334SH Users Guide Chapter 9 Network Address Translation (NAT) The following table describes the labels in this screen. Table 42 NAT General LABEL Network Address Translation DESCRIPTION Network Address Translation (NAT) allows the translation of an Internet protocol address used within one network (for example a private IP address used in a local network) to a different IP address known within another network (for example a public IP address used on the Internet). Select the check box to enable NAT. In addition to the servers for specified services, NAT supports a default server.

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 ZyXEL Device 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 ZyXEL Device's WAN port receives a response with a specific port number and protocol ("incoming" port), the ZyXEL Device 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. 9.5.1 Trigger Port Forwarding Example The following is an example of trigger port forwarding. 114 ZyXEL NBG-334SH Users Guide Chapter 9 Network Address Translation (NAT) Figure 66 Trigger Port Forwarding Process: Example 1 Jane requests a file from the Real Audio server (port 7070). 2 Port 7070 is a trigger port and causes the ZyXEL Device to record Janes computer IP address. The ZyXEL Device associates Jane's computer IP address with the "incoming"

port range of 6970-7170. 3 The Real Audio server responds using a port number ranging between 6970-7170. 4 The ZyXEL Device 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 ZyXEL Device times out in three minutes with UDP (User Datagram Protocol), or two hours with TCP/IP (Transfer Control Protocol/Internet Protocol). 9.5.2 Two Points To Remember About Trigger Ports 1 Trigger events only happen on data that is going coming from inside the ZyXEL Device and going to the outside. 2 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. 9.6 NAT Advanced Screen To change your ZyXEL Devices trigger port settings, click Network > NAT > Advanced. The screen appears as shown.

Only one LAN computer can use a trigger port (range) at a time.

Table 44 NAT Advanced LABEL Max NAT/Firewall Session Per User DESCRIPTION Type a number ranging from 1 to 2048 to limit the number of NAT/firewall sessions that a host can create. 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 ZyXEL Device. 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. This is the rule index number (read-only). Type a unique name (up to 15 characters) for identification purposes. All characters are permitted - including spaces. Incoming is a port (or a range of ports) that a server on the WAN uses when it sends out a particular service. The ZyXEL Device forwards the traffic with this port

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. 10.1.1 DynDNS Wildcard 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.

If you have a private WAN IP address, then you cannot use Dynamic DNS. 10.2 Dynamic DNS Screen To change your ZyXEL Devices DDNS, click Network > DDNS. The screen appears as shown.

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 a network that is not trusted. 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. 11.1.2 Stateful Inspection 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. 11.1.3 About the ZyXEL Device Firewall The ZyXEL Device firewall is a stateful inspection firewall and is designed to protect against Denial of Service attacks when activated (click the General tab under Firewall and then click the Enable Firewall check box). The ZyXEL Device's purpose is to allow a private Local Area Network (LAN) to be securely connected to the Internet. The ZyXEL Device 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. ZyXEL NBG-334SH Users Guide 121 Chapter 11 Firewall The ZyXEL Device is installed between the LAN and a broadband modem connecting to the Internet. This allows it to act as a secure gateway for all data passing between the Internet and the LAN. The ZyXEL Device has one Ethernet WAN port and four Ethernet LAN ports, which are used to physically separate the network into two areas.The WAN (Wide Area Network) port attaches to the broadband (cable or DSL) modem to the Internet. 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. 11.1.4 Guidelines For Enhancing Security With Your Firewall 1 Change the default password via web configurator. 2 Think about access control before you connect to the network in any way, including attaching a modem to the port. 3 Limit who can access your router. 4 Don't enable any local service (such as SNMP or NTP) 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 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. 6 Protect against IP spoofing by making sure the firewall is active. 7 Keep the firewall in a secured (locked) room. 11.2 Triangle Routes If an alternate gateway on the LAN has an IP address in the same subnet as the ZyXEL Devices LAN IP address, return traffic may not go through the ZyXEL Device. This is called an asymmetrical or triangle route. This causes the ZyXEL Device to reset the connection, as the connection has not been acknowledged. You can have the ZyXEL Device permit the use of asymmetrical route topology on the network (not reset the connection). Allowing asymmetrical routes may let traffic from the WAN go directly to the LAN without passing through the ZyXEL Device. A better solution is to use IP alias to put the ZyXEL Device and the backup gateway on separate subnets. 11.2.1 Triangle Routes and IP Alias You can use IP alias instead of allowing triangle routes. IP Alias allow you to partition your network into logical sections over the same interface. By putting your LAN and Gateway A in different subnets, all returning network traffic must pass through the ZyXEL Device to your LAN. The following steps describe such a scenario. 122 ZyXEL NBG-334SH Users Guide Chapter 11 Firewall 1 A computer on the LAN initiates a connection by sending a SYN packet to a receiving server on the WAN. 2 The ZyXEL Device reroutes the packet to Gateway A, which is in Subnet 2. 3 The reply from the WAN goes to the ZyXEL Device. 4 The ZyXEL Device then sends it to the computer on the LAN in Subnet 1. Figure 69 Using IP Alias to Solve the Triangle Route Problem 11.3 General Firewall Screen Click Security > Firewall to open the General screen. Use this screen to enable or disable the ZyXEL Devices firewall, and set up firewall logs. Figure 70 General The following table describes the labels in this screen. Table 46 Firewall General LABEL Enable Firewall DESCRIPTION Select this check box to activate the firewall. The ZyXEL Device performs access control and protects against Denial of Service (DoS) attacks when the firewall is activated. This is the direction of travel of packets. Firewall rules are grouped based on the direction of travel of packets to which they apply.

Click Reset to start configuring this screen again. Apply Reset 11.4 Services Screen Click Security > Firewall > Services. The screen appears as shown next. If an outside user attempts to probe an unsupported port on your ZyXEL Device, an ICMP response packet is automatically returned. This allows the outside user to know the ZyXEL Device exists. Use this screen to prevent the ICMP response packet from being sent. This keeps outsiders from discovering your ZyXEL Device when unsupported ports are probed. You can also use this screen to enable service blocking, enter/delete/modify the services you want to block and the date/time you want to block them. 124 ZyXEL NBG-334SH Users Guide Figure 71 Firewall Services Chapter 11 Firewall The following table describes the labels in this screen. Table 47 Firewall Services LABEL ICMP DESCRIPTION Internet Control Message Protocol is a message control and error-reporting protocol between a host server and a gateway to the Internet. ICMP uses Internet Protocol (IP) datagrams, but the messages are processed by the TCP/IP software and directly apparent to the application user. The ZyXEL Device will not respond to any incoming Ping requests when Disable is selected. Select LAN to reply to incoming LAN Ping requests. Select WAN to reply to incoming WAN Ping requests. Otherwise select LAN & WAN to reply to both incoming LAN and WAN Ping requests. Respond to Ping on ZyXEL NBG-334SH Users Guide 125 Chapter 11 Firewall Table 47 Firewall Services LABEL Do not respond to requests for unauthorized services DESCRIPTION Select this option to prevent hackers from finding the ZyXEL Device by probing for unused ports. If you select this option, the ZyXEL Device will not respond to port request(s) for unused ports, thus leaving the unused ports and the ZyXEL Device unseen. By default this option is not selected and the ZyXEL Device will reply with an ICMP Port Unreachable packet for a port probe on its unused UDP ports, and a TCP Reset packet for a port probe on its unused TCP ports. Note that the probing packets must first traverse the ZyXEL Device's firewall mechanism before reaching this anti-probing mechanism. Therefore if the firewall mechanism blocks a probing packet, the ZyXEL Device reacts based on the firewall policy, which by default, is to send a TCP reset packet for a blocked TCP packet. You can use the command "sys firewall tcprst rst [on|off]" to change this policy. When the firewall mechanism blocks a UDP packet, it drops the packet without sending a response packet. Select this check box to enable this feature. This is a list of pre-defined services (ports) you may prohibit your LAN computers from using.

See the appendices for information on how to access and use the command interpreter. 12.6.1 Domain Name or IP Address URL Checking By default, the ZyXEL Device checks the URLs domain name or IP address when performing keyword blocking. This means that the ZyXEL Device checks the characters that come before the first slash in the URL. For example, with the URL www.zyxel.com.tw/news/pressroom.php, content filtering only searches for keywords within www.zyxel.com.tw. 12.6.2 Full Path URL Checking Full path URL checking has the ZyXEL Device check the characters that come before the last slash in the URL. For example, with the URL www.zyxel.com.tw/news/pressroom.php, full path URL checking searches for keywords within www.zyxel.com.tw/news/. Use the ip urlfilter customize actionFlags 6 [disable | enable]

command to extend (or not extend) the keyword blocking search to include the URL's full path. 12.6.3 File Name URL Checking Filename URL checking has the ZyXEL Device check all of the characters in the URL. 130 ZyXEL NBG-334SH Users Guide Chapter 12 Content Filtering For example, filename URL checking searches for keywords within the URL www.zyxel.com.tw/news/pressroom.php. Use the ip urlfilter customize actionFlags 8 [disable | enable]

ZyXEL NBG-334SH Users Guide 131 Chapter 12 Content Filtering 132 ZyXEL NBG-334SH Users Guide CHAPTER 13 Static Route Screens This chapter shows you how to configure static routes for your ZyXEL Device. 13.1 Static Route Overview Each remote node specifies only the network to which the gateway is directly connected, and the ZyXEL Device has no knowledge of the networks beyond. For instance, the ZyXEL Device knows about network N2 in the following figure through remote node router R1. However, the ZyXEL Device is unable to route a packet to network N3 because it doesn't know that there is a route through the same remote node router R1 (via gateway router R2). The static routes are for you to tell the ZyXEL Device about the networks beyond the remote nodes. Figure 74 Example of Static Routing Topology 13.2 IP Static Route Screen Click Management > Static Route to open the IP Static Route screen. The following screen displays. ZyXEL NBG-334SH Users Guide 133 Chapter 13 Static Route Screens Figure 75 IP Static Route The following table describes the labels in this screen. Table 50 IP Static Route LABEL

Name Active Destination Gateway Modify DESCRIPTION This is the index number of an individual static route. The first entry is for the default route and not editable. This is the name that describes or identifies this route. This icon is turned on when this static route is active. Click the Edit icon under Modify and select the Active checkbox in the Static Route Setup screen to enable the static route. Clear the checkbox to disable this static route without having to delete the entry. This parameter specifies the IP network address of the final destination. Routing is always based on network number. This is the IP address of the gateway. The gateway is an immediate neighbor of your ZyXEL Device that will forward the packet to the destination. On the LAN, the gateway must be a router on the same segment as your ZyXEL Device; over the WAN, the gateway must be the IP address of one of the remote nodes. Click the Edit icon to open the static route setup screen. Modify a static route or create a new static route in the Static Route Setup screen. Click the Remove icon to delete a static route. 13.2.1 Static Route Setup Screen To edit a static route, click the edit icon under Modify. The following screen displays.

Table 51 Static Route Setup LABEL Route Name DESCRIPTION Enter the name of the IP static route. Leave this field blank to delete this static route. This field allows you to activate/deactivate this static route. This parameter determines if the ZyXEL Device will include this route to a remote node in its RIP broadcasts. Select this check box to keep this route private and not included in RIP broadcasts. Clear this checkbox to propagate this route to other hosts through RIP broadcasts. This parameter specifies the IP network address of the final destination. Routing is always based on network number. If you need to specify a route to a single host, use a subnet mask of 255.255.255.255 in the subnet mask field to force the network number to be identical to the host ID. Enter the IP subnet mask here. Enter the IP address of the gateway. The gateway is an immediate neighbor of your ZyXEL Device that will forward the packet to the destination. On the LAN, the gateway must be a router on the same segment as your ZyXEL Device; over the WAN, the gateway must be the IP address of one of the Remote Nodes. Metric represents the cost of transmission for routing purposes. IP routing uses hop count as the measurement of cost, with a minimum of 1 for directly connected networks. Enter a number that approximates the cost for this link. The number need not be precise, but it must be between 1 and 15. In practice, 2 or 3 is usually a good number.

You can allocate specific amounts of bandwidth capacity

(bandwidth budgets) to different bandwidth rules. The ZyXEL Device applies bandwidth management to traffic that it forwards out through an interface. The ZyXEL Device does not control the bandwidth of traffic that comes into an interface. Bandwidth management applies to all traffic flowing out of the router, regardless of the traffic's source. Traffic redirect or IP alias may cause LAN-to-LAN traffic to pass through the ZyXEL Device and be managed by bandwidth management. The sum of the bandwidth allotments that apply to the WAN interface (LAN to WAN, WLAN to WAN, WAN to WAN / ZyXEL Device) must be less than or equal to the Upstream Bandwidth that you configure in the Bandwidth Management Advanced screen. The sum of the bandwidth allotments that apply to the LAN port (WAN to LAN, WLAN to LAN, LAN to LAN / ZyXEL Device) must be less than or equal to 100,000 kbps (you cannot configure the bandwidth budget for the LAN port). The sum of the bandwidth allotments that apply to the WLAN port (LAN to WLAN, WAN to WLAN, WLAN to WLAN / ZyXEL Device) must be less than or equal to 54,000 kbps (you cannot configure the bandwidth budget for the WLAN port). 14.2 Application-based Bandwidth Management You can create bandwidth classes based on individual applications (like VoIP, Web, FTP, E-

mail and Video for example). 14.3 Subnet-based Bandwidth Management You can create bandwidth classes based on subnets. ZyXEL NBG-334SH Users Guide 137 Chapter 14 Bandwidth Management The following figure shows LAN subnets. You could configure one bandwidth class for subnet A and another for subnet B. Figure 77 Subnet-based Bandwidth Management Example 14.4 Application and Subnet-based Bandwidth Management You could also create bandwidth classes based on a combination of a subnet and an application. The following example table shows bandwidth allocations for application specific traffic from separate LAN subnets. Table 52 Application and Subnet-based Bandwidth Management Example TRAFFIC TYPE VoIP Web FTP E-mail Video FROM SUBNET B 64 Kbps 64 Kbps 64 Kbps 64 Kbps 64 Kbps FROM SUBNET A 64 Kbps 64 Kbps 64 Kbps 64 Kbps 64 Kbps 14.5 Bandwidth Management Priorities The following table describes the priorities that you can apply to traffic that the ZyXEL Device forwards out through an interface. Table 53 Bandwidth Management Priorities PRIORITY LEVELS: TRAFFIC WITH A HIGHER PRIORITY GETS THROUGH FASTER WHILE TRAFFIC WITH A LOWER PRIORITY IS DROPPED IF THE NETWORK IS CONGESTED. High Typically used for voice traffic or video that is especially sensitive to jitter (jitter is the variations in delay). 138 ZyXEL NBG-334SH Users Guide Chapter 14 Bandwidth Management Table 53 Bandwidth Management Priorities PRIORITY LEVELS: TRAFFIC WITH A HIGHER PRIORITY GETS THROUGH FASTER WHILE TRAFFIC WITH A LOWER PRIORITY IS DROPPED IF THE NETWORK IS CONGESTED. Mid Typically used for excellent effort or better than best effort and would include important business traffic that can tolerate some delay. This is typically used for non-critical background traffic such as bulk transfers that are allowed but that should not affect other applications and users. Low 14.6 Predefined Bandwidth Management Services The following is a description of the services that you can select and to which you can apply media bandwidth management using the wizard screens. Table 54 Media Bandwidth Management Setup: Services SERVICE Xbox Live VoIP (SIP) FTP E-Mail BitTorrent MSN Webcam WWW DESCRIPTION This is Microsofts online gaming service that lets you play multiplayer Xbox games on the Internet via broadband technology. Xbox Live uses port 3074. Sending voice signals over the Internet is called Voice over IP or VoIP. Session Initiated Protocol (SIP) is an internationally recognized standard for implementing VoIP. SIP is an application-layer control (signaling) protocol that handles the setting up, altering and tearing down of voice and multimedia sessions over the Internet. SIP is transported primarily over UDP but can also be transported over TCP, using the default port number 5060. File Transfer Program enables fast transfer of files, including large files that may not be possible by e-mail. FTP uses port number 21. Electronic mail consists of messages sent through a computer network to specific groups or individuals. Here are some default ports for e-mail:

POP3 - port 110 IMAP - port 143 SMTP - port 25 HTTP - port 80 BitTorrent is a free P2P (peer-to-peer) sharing tool allowing you to distribute large software and media files using ports 6881 to 6889. BitTorrent requires you to search for a file with a searching engine yourself. It distributes files by corporation and trading, that is, the client downloads the file in small pieces and share the pieces with other peers to get other half of the file. MSN messenger allows you to chat online and send instant messages. If you use MSN messenger and also have a webcam, you can send your image/photo in real-time along with messages The World Wide Web (WWW) is an Internet system to distribute graphical, hyper-

linked information, based on Hyper Text Transfer Protocol (HTTP) - a client/server protocol for the World Wide Web. The Web is not synonymous with the Internet;

rather, it is just one service on the Internet. Other services on the Internet include Internet Relay Chat and Newsgroups. The Web is accessed through use of a browser.

When you configure remote management to allow management from the WAN, you still need to configure a firewall rule to allow access. See the firewall chapters for details on configuring firewall rules. You may manage your ZyXEL Device from a remote location via:

Table 61 ALL (LAN and WAN) Neither (Disable). Internet (WAN only) LAN only

When you choose WAN or LAN & WAN, you still need to configure a firewall rule to allow access. To disable remote management of a service, select Disable in the corresponding Server Access field. You may only have one remote management session running at a time. The ZyXEL Device automatically disconnects a remote management session of lower priority when another remote management session of higher priority starts. The priorities for the different types of remote management sessions are as follows. 1 Telnet 2 HTTP ZyXEL NBG-334SH Users Guide 149 Chapter 15 Remote Management Screens 15.1.1 Remote Management Limitations Remote management over LAN or WAN will not work when:

1 You have disabled that service in one of the remote management screens. 2 The IP address in the Secured Client IP Address field does not match the client IP address. If it does not match, the ZyXEL Device will disconnect the session immediately. 3 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. 4 There is a firewall rule that blocks it. 15.1.2 Remote Management and NAT When NAT is enabled:

Use the ZyXEL Devices WAN IP address when configuring from the WAN. Use the ZyXEL Devices LAN IP address when configuring from the LAN. 15.1.3 System Timeout There is a default system management idle timeout of five minutes (three hundred seconds). The ZyXEL Device 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.

A UPnP device can dynamically join a network, obtain an IP address, convey its capabilities and learn about other devices on the network. In turn, a device can leave a network smoothly and automatically when it is no longer in use. See Section 16.3 on page 156 for configuration instructions. 16.1.1 How do I know if I'm using UPnP?

UPnP hardware is identified as an icon in the Network Connections folder (Windows XP). Each UPnP compatible device installed on your network will appear as a separate icon. Selecting the icon of a UPnP device will allow you to access the information and properties of that device. 16.1.2 NAT Traversal UPnP NAT traversal automates the process of allowing an application to operate through NAT. UPnP network devices can automatically configure network addressing, announce their presence in the network to other UPnP devices and enable exchange of simple product and service descriptions. NAT traversal allows the following:

Dynamic port mapping Learning public IP addresses Assigning lease times to mappings Windows Messenger is an example of an application that supports NAT traversal and UPnP. See the NAT chapter for more information on NAT. 16.1.3 Cautions with UPnP The automated nature of NAT traversal applications in establishing their own services and opening firewall ports may present network security issues. Network information and configuration may also be obtained and modified by users in some network environments. ZyXEL NBG-334SH Users Guide 155 Chapter 16 Universal Plug-and-Play (UPnP) When a UPnP device joins a network, it announces its presence with a multicast message. For security reasons, the ZyXEL Device allows multicast messages on the LAN only. All UPnP-enabled devices may communicate freely with each other without additional configuration. Disable UPnP if this is not your intention. 16.2 UPnP and ZyXEL ZyXEL has achieved UPnP certification from the Universal Plug and Play Forum UPnP Implementers Corp. (UIC). ZyXEL's UPnP implementation supports Internet Gateway Device

(IGD) 1.0. See the following sections for examples of installing and using UPnP. 16.3 UPnP Screen Click the Management > UPnP to display the UPnP screen. Figure 88 Configuring UPnP The following table describes the labels in this screen. Table 66 Configuring UPnP LABEL Active the Universal Plug and Play (UPnP) Feature Allow users to make configuration changes through UPnP Allow UPnP to pass through Firewall DESCRIPTION Select this check box to activate UPnP. Be aware that anyone could use a UPnP application to open the web configurator's login screen without entering the ZyXEL Device's IP address (although you must still enter the password to access the web configurator). Select this check box to allow UPnP-enabled applications to automatically configure the ZyXEL Device so that they can communicate through the ZyXEL Device, for example by using NAT traversal, UPnP applications automatically reserve a NAT forwarding port in order to communicate with another UPnP enabled device; this eliminates the need to manually configure port forwarding for the UPnP enabled application. Select this check box to allow traffic from UPnP-enabled applications to bypass the firewall. Clear this check box to have the firewall block all UPnP application packets (for example, MSN packets). 156 ZyXEL NBG-334SH Users Guide Chapter 16 Universal Plug-and-Play (UPnP) Table 66 Configuring UPnP LABEL Apply Cancel DESCRIPTION Click Apply to save the setting to the ZyXEL Device.

(up to 20 extended ASCII characters in length) of your time server. Check with your ISP/network administrator if you are unsure of this information. Choose the time zone of your location. This will set the time difference between your time zone and Greenwich Mean Time (GMT). Daylight saving is a period from late spring to early fall when many countries set their clocks ahead of normal local time by one hour to give more daytime light in the evening. Select this option if you use Daylight Saving Time. Configure the day and time when Daylight Saving Time starts if you selected Daylight Savings. The o'clock field uses the 24 hour format. Here are a couple of examples:

Daylight Saving Time starts in most parts of the United States on the first Sunday of April. Each time zone in the United States starts using Daylight Saving Time at 2 A.M. local time. So in the United States you would select First, Sunday, April and type 2 in the o'clock field. Daylight Saving Time starts in the European Union on the last Sunday of March. All of the time zones in the European Union start using Daylight Saving Time at the same moment (1 A.M. GMT or UTC). So in the European Union you would select Last, Sunday, March. The time you type in the o'clock field depends on your time zone. In Germany for instance, you would type 2 because Germany's time zone is one hour ahead of GMT or UTC (GMT+1). Configure the day and time when Daylight Saving Time ends if you selected Daylight Savings. The o'clock field uses the 24 hour format. Here are a couple of examples:

Daylight Saving Time ends in the United States on the last Sunday of October. Each time zone in the United States stops using Daylight Saving Time at 2 A.M. local time. So in the United States you would select Last, Sunday, October and type 2 in the o'clock field. Daylight Saving Time ends in the European Union on the last Sunday of October. All of the time zones in the European Union stop using Daylight Saving Time at the same moment (1 A.M. GMT or UTC). So in the European Union you would select Last, Sunday, October. The time you type in the o'clock field depends on your time zone. In Germany for instance, you would type 2 because Germany's time zone is one hour ahead of GMT or UTC (GMT+1).

(denoted by its number) and was blocked or forwarded according to the rule. The firewall allowed a triangle route session to pass through. The router blocked a packet that didn't have a corresponding NAT table entry. The router sent a message to notify a user that the router blocked access to a web site that the user requested. Table 74 TCP Reset Logs LOG MESSAGE Under SYN flood attack, sent TCP RST Exceed TCP MAX incomplete, sent TCP RST Peer TCP state out of order, sent TCP RST DESCRIPTION The router sent a TCP reset packet when a host was under a SYN flood attack (the TCP incomplete count is per destination host.) 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.) Note: Refer to TCP Maximum Incomplete in the Firewall Attack Alerts screen. 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. 178 ZyXEL NBG-334SH Users Guide Table 74 TCP Reset Logs (continued) LOG MESSAGE Firewall session time out, sent TCP RST Exceed MAX incomplete, sent TCP RST Access block, sent TCP RST Chapter 18 Logs DESCRIPTION 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 < Maximum Incomplete Low. The router sends a TCP RST packet and generates this log if you turn on the firewall TCP reset mechanism (via CI command: "sys firewall tcprst"). Table 75 Packet Filter Logs LOG MESSAGE

Download new firmware (when available) from the ZyXEL web site and use the web configurator, an FTP or a TFTP tool to put it on the ZyXEL Device. Note: Only upload firmware for your specific model!

Make a copy of the ZyXEL Devices configuration and put it back on the ZyXEL Device later if you decide you want to revert back to an earlier configuration. Each computer on your network must have its own unique IP address. Use NAT to convert a single public IP address to multiple private IP addresses for the computers on your network. You can configure firewall on the ZyXEL Device for secure Internet access. When the firewall is on, by default, all incoming traffic from the Internet to your network is blocked unless it is initiated from your network. This means that probes from the outside to your network are not allowed, but you can safely browse the Internet and download files for example. The ZyXEL Device blocks or allows access to web sites that you specify and blocks access to web sites with URLs that contain keywords that you specify. You can define time periods and days during which content filtering is enabled. You can also include or exclude particular computers on your network from content filtering. You can also subscribe to category-based content filtering that allows your ZyXEL Device to check web sites against an external database. You can efficiently manage traffic on your network by reserving bandwidth and giving priority to certain types of traffic and/or to particular computers. Get the current time and date from an external server when you turn on your ZyXEL Device. You can also set the time manually. These dates and times are then used in logs. If you have a server (mail or web server for example) on your network, then use this feature to let people access it from the Internet. Use this feature to have the ZyXEL Device assign IP addresses, an IP default gateway and DNS servers to computers on your network. With Dynamic DNS (Domain Name System) support, you can use a fixed URL, www.zyxel.com for example, with a dynamic IP address. You must register for this service with a Dynamic DNS service provider. IP Multicast is used to send traffic to a specific group of computers. The ZyXEL Device supports versions 1 and 2 of IGMP (Internet Group Management Protocol) used to join multicast groups (see RFC 2236). IP Alias allows you to subdivide a physical network into logical networks over the same Ethernet interface with the ZyXEL Device itself as the gateway for each subnet. 204 ZyXEL NBG-334SH Users Guide Appendix A Product Specifications Table 92 Firmware Features FEATURE Logging and Tracing PPPoE PPTP Encapsulation Universal Plug and Play

Figure 124 Java (Sun) 212 ZyXEL NBG-334SH Users Guide APPENDIX C IP Addresses and Subnetting This appendix introduces IP addresses and subnet masks. 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. 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. ZyXEL NBG-334SH Users Guide 213 Appendix C IP Addresses and Subnetting Figure 125 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). Table 93 Subnet Mask - Identifying Network Number IP Address (Binary) Subnet Mask (Binary) Network Number Host ID 1ST OCTET:

(192) 11000000 11111111 11000000 2ND OCTET:

(2) 00000010 00000000 00000010 By convention, subnet masks always consist of a continuous sequence of ones beginning from the leftmost bit of the mask, followed by a continuous sequence of zeros, for a total number of 32 bits. 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. 214 ZyXEL NBG-334SH Users Guide Appendix C IP Addresses and Subnetting 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. Table 94 Subnet Masks BINARY 1ST OCTET 11111111 11111111 11111111 11111111 8-bit mask 16-bit mask 24-bit mask 29-bit mask 2ND OCTET 00000000 11111111 11111111 11111111 3RD OCTET 00000000 00000000 11111111 11111111 4TH OCTET DECIMAL 00000000 00000000 00000000 11111000 255.0.0.0 255.255.0.0 255.255.255.0 255.255.255.248 Network Size The size of the network number determines the maximum number of possible hosts you can have on your network. 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:

Table 95 Maximum Host Numbers SUBNET MASK 8 bits 16 bits 24 bits 29 bits HOST ID SIZE 24 bits 255.0.0.0 16 bits 255.255.0.0 255.255.255.0 8 bits 255.255.255.248 3 bits MAXIMUM NUMBER OF HOSTS 16777214 65534 254 6 224 2 216 2 28 2 23 2 Notation Since the mask is always a continuous number of ones beginning from the left, followed by a continuous number of zeros for the remainder of the 32 bit mask, you can simply specify the number of ones instead of writing the value of each octet. 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. The following table shows some possible subnet masks using both notations. Table 96 Alternative Subnet Mask Notation SUBNET MASK 255.255.255.0 255.255.255.128 ALTERNATIVE NOTATION

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. The following figure shows the company network before subnetting. Figure 126 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. The following figure shows the company network after subnetting. There are now two sub-

networks, A and B. 216 ZyXEL NBG-334SH Users Guide Figure 127 Subnetting Example: After Subnetting Appendix C IP Addresses and 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. 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).

HOSTS PER SUBNET 2 1 Configuring IP Addresses 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. 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 ZyXEL Device. Once you have decided on the network number, pick an IP address for your ZyXEL Device 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 ZyXEL Device 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 ZyXEL Device 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. 220 ZyXEL NBG-334SH Users Guide APPENDIX D Wall-mounting Instructions Do the following to hang your ZyXEL Device on a wall.

See the product specifications appendix for the size of screws to use and how far apart to place them. 1 Locate a high position on a wall that is free of obstructions. Use a sturdy wall. 2 Drill two holes for the screws. Make sure the distance between the centers of the holes matches what is listed in the product specifications appendix.

Be careful to avoid damaging pipes or cables located inside the wall when drilling holes for the screws. 3 Do not screw the screws all the way into the wall. Leave a small gap of about 0.5 cm between the heads of the screws and the wall. 4 Make sure the screws are snugly fastened to the wall. They need to hold the weight of the ZyXEL Device with the connection cables. 5 Align the holes on the back of the ZyXEL Device with the screws on the wall. Hang the ZyXEL Device on the screws.

238 ZyXEL NBG-334SH Users Guide APPENDIX F Wireless LANs Wireless LAN Topologies This section discusses ad-hoc and infrastructure wireless LAN topologies. Ad-hoc Wireless LAN Configuration The simplest WLAN configuration is an independent (Ad-hoc) WLAN that connects a set of computers with wireless stations (A, B, C). Any time two or more wireless adapters are within range of each other, they can set up an independent network, which is commonly referred to as an Ad-hoc network or Independent Basic Service Set (IBSS). The following diagram shows an example of notebook computers using wireless adapters to form an Ad-hoc wireless LAN. Figure 152 Peer-to-Peer Communication in an Ad-hoc Network BSS A Basic Service Set (BSS) exists when all communications between wireless stations or between a wireless station and a wired network client go through one access point (AP). Intra-BSS traffic is traffic between wireless stations in the BSS. When Intra-BSS is enabled, wireless station A and B can access the wired network and communicate with each other. When Intra-BSS is disabled, wireless station A and B can still access the wired network but cannot communicate with each other. ZyXEL NBG-334SH Users Guide 239 Appendix F Wireless LANs Figure 153 Basic Service Set ESS An Extended Service Set (ESS) consists of a series of overlapping BSSs, each containing an access point, with each access point connected together by a wired network. This wired connection between APs is called a Distribution System (DS). This type of wireless LAN topology is called an Infrastructure WLAN. The Access Points not only provide communication with the wired network but also mediate wireless network traffic in the immediate neighborhood. An ESSID (ESS IDentification) uniquely identifies each ESS. All access points and their associated wireless stations within the same ESS must have the same ESSID in order to communicate. 240 ZyXEL NBG-334SH Users Guide Figure 154 Infrastructure WLAN Appendix F Wireless LANs Channel A channel is the radio frequency(ies) used by IEEE 802.11a/b/g wireless devices. Channels available depend on your geographical area. You may have a choice of channels (for your region) so you should use a different channel than an adjacent AP (access point) to reduce interference. Interference occurs when radio signals from different access points overlap causing interference and degrading performance. Adjacent channels partially overlap however. To avoid interference due to overlap, your AP should be on a channel at least five channels away from a channel that an adjacent AP is using. For example, if your region has 11 channels and an adjacent AP is using channel 1, then you need to select a channel between 6 or 11. RTS/CTS A hidden node occurs when two stations are within range of the same access point, but are not within range of each other. The following figure illustrates a hidden node. Both stations (STA) are within range of the access point (AP) or wireless gateway, but out-of-range of each other, so they cannot "hear" each other, that is they do not know if the channel is currently being used. Therefore, they are considered hidden from each other. ZyXEL NBG-334SH Users Guide 241 Appendix F Wireless LANs Figure 155 RTS/CTS When station A sends data to the AP, it might not know that the station B is already using the channel. If these two stations send data at the same time, collisions may occur when both sets of data arrive at the AP at the same time, resulting in a loss of messages for both stations. RTS/CTS is designed to prevent collisions due to hidden nodes. An RTS/CTS defines the biggest size data frame you can send before an RTS (Request To Send)/CTS (Clear to Send) handshake is invoked. When a data frame exceeds the RTS/CTS value you set (between 0 to 2432 bytes), the station that wants to transmit this frame must first send an RTS (Request To Send) message to the AP for permission to send it. The AP then responds with a CTS (Clear to Send) message to all other stations within its range to notify them to defer their transmission. It also reserves and confirms with the requesting station the time frame for the requested transmission. Stations can send frames smaller than the specified RTS/CTS directly to the AP without the RTS (Request To Send)/CTS (Clear to Send) handshake. You should only configure RTS/CTS if the possibility of hidden nodes exists on your network and the "cost" of resending large frames is more than the extra network overhead involved in the RTS (Request To Send)/CTS (Clear to Send) handshake. If the RTS/CTS value is greater than the Fragmentation Threshold value (see next), then the RTS (Request To Send)/CTS (Clear to Send) handshake will never occur as data frames will be fragmented before they reach RTS/CTS size.

Enabling the RTS Threshold causes redundant network overhead that could negatively affect the throughput performance instead of providing a remedy. Fragmentation Threshold A Fragmentation Threshold is the maximum data fragment size (between 256 and 2432 bytes) that can be sent in the wireless network before the AP will fragment the packet into smaller data frames. A large Fragmentation Threshold is recommended for networks not prone to interference while you should set a smaller threshold for busy networks or networks that are prone to interference. 242 ZyXEL NBG-334SH Users Guide Appendix F Wireless LANs If the Fragmentation Threshold value is smaller than the RTS/CTS value (see previously) you set then the RTS (Request To Send)/CTS (Clear to Send) handshake will never occur as data frames will be fragmented before they reach RTS/CTS size. Preamble Type A preamble is used to synchronize the transmission timing in your wireless network. There are two preamble modes: Long and Short. Short preamble takes less time to process and minimizes overhead, so it should be used in a good wireless network environment when all wireless stations support it. Select Long if you have a noisy network or are unsure of what preamble mode your wireless stations support as all IEEE 802.11b compliant wireless adapters must support long preamble. However, not all wireless adapters support short preamble. Use long preamble if you are unsure what preamble mode the wireless adapters support, to ensure interpretability between the AP and the wireless stations and to provide more reliable communication in noisy networks. Select Dynamic to have the AP automatically use short preamble when all wireless stations support it, otherwise the AP uses long preamble.

The AP and the wireless stations MUST use the same preamble mode in order to communicate. IEEE 802.11g Wireless LAN IEEE 802.11g is fully compatible with the IEEE 802.11b standard. This means an IEEE 802.11b adapter can interface directly with an IEEE 802.11g access point (and vice versa) at 11 Mbps or lower depending on range. IEEE 802.11g has several intermediate rate steps between the maximum and minimum data rates. The IEEE 802.11g data rate and modulation are as follows:

Table 104 IEEE 802.11g DATA RATE (MBPS) MODULATION 1 2 5.5 / 11 6/9/12/18/24/36/48/54 OFDM (Orthogonal Frequency Division Multiplexing) DBPSK (Differential Binary Phase Shift Keyed) DQPSK (Differential Quadrature Phase Shift Keying) CCK (Complementary Code Keying) IEEE 802.1x In June 2001, the IEEE 802.1x standard was designed to extend the features of IEEE 802.11 to support extended authentication as well as providing additional accounting and control features. It is supported by Windows XP and a number of network devices. Some advantages of IEEE 802.1x are:

ZyXEL NBG-334SH Users Guide 243 Appendix F Wireless LANs User based identification that allows for roaming. Support for RADIUS (Remote Authentication Dial In User Service, RFC 2138, 2139) for centralized user profile and accounting management on a network RADIUS server. Support for EAP (Extensible Authentication Protocol, RFC 2486) that allows additional authentication methods to be deployed with no changes to the access point or the wireless stations. RADIUS RADIUS is based on a client-server model that supports authentication, authorization and accounting. The access point 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 AP acts as a message relay between the wireless station and the network RADIUS server. Types of RADIUS Messages The following types of RADIUS messages are exchanged between the access point and the RADIUS server for user authentication:

Access-Request Sent by an access point 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 access point sends a proper response from the user and then sends another Access-Request message. The following types of RADIUS messages are exchanged between the access point and the RADIUS server for user accounting:

Accounting-Request Sent by the access point requesting accounting. Accounting-Response Sent by the RADIUS server to indicate that it has started or stopped accounting. 244 ZyXEL NBG-334SH Users Guide Appendix F Wireless LANs 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 the network. In addition to the shared key, password information exchanged is also encrypted to protect the network from unauthorized access. Types of Authentication This appendix discusses some popular authentication types: EAP-MD5, EAP-TLS, EAP-

TTLS, PEAP and LEAP. The type of authentication you use depends on the RADIUS server or the AP. Consult your network administrator for more information. EAP-MD5 (Message-Digest Algorithm 5) MD5 authentication is the simplest one-way authentication method. The authentication server sends a challenge to the wireless station. The wireless station proves that it knows the password by encrypting the password with the challenge and sends back the information. Password is not sent in plain text. However, MD5 authentication has some weaknesses. Since the authentication server needs to get the plaintext passwords, the passwords must be stored. Thus someone other than the authentication server may access the password file. In addition, it is possible to impersonate an authentication server as MD5 authentication method does not perform mutual authentication. Finally, MD5 authentication method does not support data encryption with dynamic session key. You must configure WEP encryption keys for data encryption. EAP-TLS (Transport Layer Security) With EAP-TLS, digital certifications are needed by both the server and the wireless stations for mutual authentication. The server presents a certificate to the client. After validating the identity of the server, the client sends a different certificate to the server. The exchange of certificates is done in the open before a secured tunnel is created. This makes user identity vulnerable to passive attacks. A digital certificate is an electronic ID card that authenticates the senders identity. However, to implement EAP-TLS, you need a Certificate Authority (CA) to handle certificates, which imposes a management overhead. 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. 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. ZyXEL NBG-334SH Users Guide 245 Appendix F Wireless LANs PEAP (Protected EAP) Like EAP-TTLS, server-side certificate authentication is used to establish a secure connection, then use simple username and password methods through the secured connection to authenticate the clients, thus hiding client identity. However, PEAP only supports EAP methods, such as EAP-MD5, EAP-MSCHAPv2 and EAP-GTC (EAP-Generic Token Card), for client authentication. EAP-GTC is implemented only by Cisco. LEAP LEAP (Lightweight Extensible Authentication Protocol) is a Cisco implementation of IEEE 802.1x. Dynamic WEP Key Exchange The AP maps a unique key that is generated with the RADIUS server. This key expires when the wireless connection times out, disconnects or reauthentication times out. A new WEP key is generated each time reauthentication is performed. If this feature is enabled, it is not necessary to configure a default encryption key in the Wireless screen. You may still configure and store keys here, but they will not be used while Dynamic WEP is enabled.

EAP-MD5 cannot be used with dynamic WEP key exchange For added security, certificate-based authentications (EAP-TLS, EAP-TTLS and PEAP) use dynamic keys for data encryption. They are often deployed in corporate environments, but for public deployment, a simple user name and password pair is more practical. The following table is a comparison of the features of authentication types. Table 105 Comparison of EAP Authentication Types Mutual Authentication Certificate Client Certificate Server Dynamic Key Exchange Credential Integrity Deployment Difficulty Client Identity Protection EAP-MD5 No No No No None Easy No EAP-TLS Yes Yes Yes Yes Strong Hard No EAP-TTLS Yes Optional Yes Yes Strong Moderate Yes PEAP Yes Optional Yes Yes Strong Moderate Yes LEAP Yes No No Yes Moderate Moderate No WPA(2) Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. WPA2 (IEEE 802.11i) is a wireless security standard that defines stronger encryption, authentication and key management than WPA. 246 ZyXEL NBG-334SH Users Guide Key differences between WPA(2) and WEP are improved data encryption and user authentication. Encryption Appendix F Wireless LANs Both WPA and WPA2 improve data encryption by using Temporal Key Integrity Protocol

(TKIP), Message Integrity Check (MIC) and IEEE 802.1x. In addition to TKIP, WPA2 also uses Advanced Encryption Standard (AES) in the Counter mode with Cipher block chaining Message authentication code Protocol (CCMP) to offer stronger encryption. Temporal Key Integrity Protocol (TKIP) uses 128-bit keys that are dynamically generated and distributed by the authentication server. It includes a per-packet key mixing function, a Message Integrity Check (MIC) named Michael, an extended initialization vector (IV) with sequencing rules, and a re-keying mechanism. TKIP regularly changes and rotates the encryption keys so that the same encryption key is never used twice. The RADIUS server distributes a Pairwise Master Key (PMK) key to the AP that then sets up a key hierarchy and management system, using the pair-wise key to dynamically generate unique data encryption keys to encrypt every data packet that is wirelessly communicated between the AP and the wireless clients. This all happens in the background automatically. WPA2 AES (Advanced Encryption Standard) is a block cipher that uses a 256-bit mathematical algorithm called Rijndael. The Message Integrity Check (MIC) is designed to prevent an attacker from capturing data packets, altering them and resending them. The MIC provides a strong mathematical function in which the receiver and the transmitter each compute and then compare the MIC. If they do not match, it is assumed that the data has been tampered with and the packet is dropped. By generating unique data encryption keys for every data packet and by creating an integrity checking mechanism (MIC), TKIP makes it much more difficult to decode data on a Wi-Fi network than WEP, making it difficult for an intruder to break into the network. The encryption mechanisms used for WPA and WPA-PSK are the same. The only difference between the two is that WPA-PSK uses a simple common password, instead of user-specific credentials. The common-password approach makes WPA-PSK susceptible to brute-force password-guessing attacks but it's still an improvement over WEP as it employs an easier-to-

use, consistent, single, alphanumeric password. User Authentication WPA or WPA2 applies IEEE 802.1x and Extensible Authentication Protocol (EAP) to authenticate wireless clients using an external RADIUS database. If both an AP and the wireless clients support WPA2 and you have an external RADIUS server, use WPA2 for stronger data encryption. If you don't have an external RADIUS server, you should use WPA2 -PSK (WPA2 -Pre-Shared Key) that only requires a single (identical) password entered into each access point, wireless gateway and wireless client. As long as the passwords match, a wireless client will be granted access to a WLAN. If the AP or the wireless clients do not support WPA2, just use WPA or WPA-PSK depending on whether you have an external RADIUS server or not. Select WEP only when the AP and/or wireless clients do not support WPA or WPA2. WEP is less secure than WPA or WPA2. ZyXEL NBG-334SH Users Guide 247 Appendix F Wireless LANs 21.5.2 WPA(2)-PSK Application Example A WPA(2)-PSK application looks as follows. 1 First enter identical passwords into the AP and all wireless clients. The Pre-Shared Key

(PSK) must consist of between 8 and 63 ASCII characters (including spaces and symbols). 2 The AP checks each wireless client's password and (only) allows it to join the network if the password matches. 3 The AP derives and distributes keys to the wireless clients. 4 The AP and wireless clients use the TKIP or AES encryption process to encrypt data exchanged between them. Figure 156 WPA(2)-PSK Authentication 21.5.3 WPA(2) with RADIUS Application Example You need the IP address of the RADIUS server, its port number (default is 1812), and the RADIUS shared secret. A WPA(2) application example with an external RADIUS server looks as follows. "A" is the RADIUS server. "DS" is the distribution system. 1 The AP passes the wireless client's authentication request to the RADIUS server. 2 The RADIUS server then checks the user's identification against its database and grants or denies network access accordingly. 3 The RADIUS server distributes a Pairwise Master Key (PMK) key to the AP that then sets up a key hierarchy and management system, using the pair-wise key to dynamically generate unique data encryption keys to encrypt every data packet that is wirelessly communicated between the AP and the wireless clients. 248 ZyXEL NBG-334SH Users Guide Security Parameters Summary Appendix F Wireless LANs Refer to this table to see what other security parameters you should configure for each Authentication Method/ key management protocol type.

See Appendix G on page 251 for information on the command structure. Introduction NetBIOS (Network Basic Input/Output System) are TCP or UDP broadcast packets that enable a computer to connect to and communicate with a LAN. For some dial-up services such as PPPoE or PPTP, NetBIOS packets cause unwanted calls. You can configure NetBIOS filters to do the following:

Allow or disallow the sending of NetBIOS packets from the LAN to the WAN and from the WAN to the LAN. Allow or disallow the sending of NetBIOS packets from the LAN to the DMZ and from the DMZ to the LAN. Allow or disallow the sending of NetBIOS packets from the WAN to the DMZ and from the DMZ to the WAN. Allow or disallow the sending of NetBIOS packets through VPN connections. Allow or disallow NetBIOS packets to initiate calls. Display NetBIOS Filter Settings Syntax:

All menus shown in this appendix are example menus meant to show SPTGEN usage. Actual menus for your product may differ. Internal SPTGEN Overview Internal SPTGEN (System Parameter Table Generator) is a configuration text file useful for efficient configuration of multiple ZyXEL Devices. Internal SPTGEN lets you configure, save and upload multiple menus at the same time using just one configuration text file eliminating the need to navigate and configure individual screens for each ZyXEL Device. You can use FTP to get the Internal SPTGEN file. Then edit the file in a text editor and use FTP to upload it again to the same device or another one. See the following sections for details. The Configuration Text File Format All Internal SPTGEN text files conform to the following format:

<field identification number = field name = parameter values allowed = input>, where <input> is your input conforming to <parameter values allowed>. The figure shown next is an example of an Internal SPTGEN text file. Figure 159 Configuration Text File Format: Column Descriptions

DO NOT alter or delete any field except parameters in the Input column. This appendix introduces Internal SPTGEN. All menus shown in this appendix are example menus meant to show SPTGEN usage. Actual menus for your product may differ. Internal SPTGEN File Modification - Important Points to Remember Each parameter you enter must be preceded by one =sign and one space. Some parameters are dependent on others. For example, if you disable the Configured field in menu 1 (see Figure 159 on page 261), then you disable every field in this menu. If you enter a parameter that is invalid in the Input column, the ZyXEL Device will not save the configuration and the command line will display the Field Identification Number. Figure 160 on page 262, shown next, is an example of what the ZyXEL Device displays if you enter a value other than 0 or 1 in the Input column of Field Identification Number 1000000
