WPS is an industry standard specification, defined by the WiFi Alliance. WPS allows you to quickly set up a wireless network with strong security, without having to configure security settings manually. Each WPS connection works between two devices. Both devices must support WPS (check each devices documentation to make sure). Depending on the devices you have, you can either press a button (on the device itself, or in its configuration utility) or enter a PIN (a unique Personal Identification Number that allows one device to authenticate the other) in each of the two devices. When WPS is activated on a device, it has two minutes to find another device that also has WPS activated. Then, the two devices connect and set up a secure network by themselves. For more information on using WPS, see Section 6.2 on page 43. EMG1302-R10A Users Guide 17 Chapter 1 Introduction 1.7 Wall Mounting You may need screw anchors if mounting on a concrete or brick wall.

EMG1302-R10A Users Guide 41 Chapter 5 Router Mode 42 EMG1302-R10A Users Guide CHAPTER 6 Tutorials 6.1 Overview This chapter provides tutorials for setting up your EMG1302-R10A. Set Up a Wireless Network with WPS Configure Wireless Security without WPS Using Multiple SSIDs on the EMG1302-R10A 6.2 Set Up a Wireless Network with WPS This section gives you an example of how to set up wireless network using WPS. This example uses the EMG1302-R10A as the AP and as the wireless client which connects to a notebook. Note: The wireless client must be a WPS-aware device (for example, a WPS USB adapter or PCI card). There are two WPS methods for creating a secure connection. This tutorial shows you how to do both. Push Button Configuration (PBC) - create a secure wireless network simply by pressing a button. See Section 6.2.1 on page 43.This is the easier method. PIN Configuration - create a secure wireless network simply by entering a wireless client's PIN

(Personal Identification Number) in the EMG1302-R10As interface. See Section 6.2.2 on page 44. This is the more secure method, since one device can authenticate the other. 6.2.1 Push Button Configuration (PBC) 1 Make sure that your EMG1302-R10A is turned on. Make sure the device is placed within range of your computer. 2 Make sure that you have installed the wireless client (this example uses the ) driver and utility in your notebook. 3 4 In the wireless client utility, find the WPS settings. Enable WPS and press the WPS button (Start or WPS button). Log into EMG1302-R10As Web Configurator and press the Push Button in the Configuration >

Network > Wireless LAN > WPS Station screen. EMG1302-R10A Users Guide 43 Chapter 6 Tutorials Note: Your EMG1302-R10A has a WPS button located on top panel, as well as a WPS button in its configuration utility. Both buttons have exactly the same function; you can use one or the other. Note: It doesnt matter which button is pressed first. You must press the second button within two minutes of pressing the first one. The EMG1302-R10A sends the proper configuration settings to the wireless client. This may take up to two minutes. Then the wireless client is able to communicate with the EMG1302-R10A securely. The following figure shows you an example to set up wireless network and security by pressing a button on both EMG1302-R10A and wireless client (the in this example). Figure 22 Example WPS Process: PBC Method Wireless Client Access Point WITHIN 2 MINUTES SECURITY INFO COMMUNICATION 6.2.2 PIN Configuration When you use the PIN configuration method, you need to use both EMG1302-R10As configuration interface and the clients utilities. Launch your wireless clients configuration utility. Go to the WPS settings and select the PIN method to get a PIN number. Enter the PIN number to the PIN field in the Configuration > Network > Wireless LAN > WPS Station screen on the EMG1302-R10A. EMG1302-R10A Users Guide 1 2 44 Chapter 6 Tutorials 3 Click Start buttons (or button next to the PIN field) on both the wireless client utility screen and the EMG1302-R10As WPS Station screen within two minutes. The EMG1302-R10A authenticates the wireless client and sends the proper configuration settings to the wireless client. This may take up to two minutes. Then the wireless client is able to communicate with the EMG1302-R10A securely. The following figure shows you the example to set up wireless network and security on EMG1302-

R10A and wireless client (ex. in this example) by using PIN method.

If you are able to access the web site, your wireless connection is successfully configured. 6.4 Using Multiple SSIDs on the EMG1302-R10A You can configure more than one SSID on a EMG1302-R10A when it is operating in access point or universal repeater mode. This allows you to configure multiple independent wireless networks on the EMG1302-R10A as if there were multiple APs (virtual APs). Each virtual AP has its own SSID, wireless security type and MAC filtering settings. That is, each SSID on the EMG1302-R10A represents a different access point/wireless network to wireless clients in the network. Clients can associate only with the SSIDs for which they have the correct security settings. Clients using different SSIDs can access the Internet and the wired network behind the EMG1302-R10A

(such as a printer). You can allow communication between wireless clients of different SSIDs in the Configuration > Network > Wireless LAN > General screen. See Section 8.4 on page 78 for more information. EMG1302-R10A Users Guide 49 Chapter 6 Tutorials For example, you may set up three wireless networks (A, B and C) in your office.

Use these screens to configure your EMG1302-R10A for Internet access. A WAN (Wide Area Network) connection is an outside connection to another network or the Internet. It connects your private networks such as a LAN (Local Area Network) and other networks, so that a computer in one location can communicate with computers in other locations. Figure 24 LAN and WAN LAN WAN 7.2 What You Can Do Use the Management WAN screen to enter your ISP information and set how the computer acquires its IP, DNS and WAN MAC addresses (Section 7.4 on page 59). Use the Advanced screen to enable multicasting and auto-IP-change (Section 7.5 on page 72). EMG1302-R10A Users Guide 55 Chapter 7 WAN 7.3 What You Need To Know The information in this section can help you configure the screens for your WAN connection, as well as enable/disable some advanced features of your EMG1302-R10A. 7.3.1 Configuring Your Internet Connection Encapsulation Method Encapsulation is used to include data from an upper layer protocol into a lower layer protocol. To set up a WAN connection to the Internet, you need to use the same encapsulation method used by your ISP (Internet Service Provider). If your ISP offers a dial-up Internet connection using PPPoE (PPP over Ethernet) or PPTP (Point-to-Point Tunneling Protocol), they should also provide a username and password (and service name) for user authentication. WAN IP Address The WAN IP address is an IP address for the EMG1302-R10A, which makes it accessible from an outside network. It is used by the EMG1302-R10A to communicate with other devices in other networks. It can be static (fixed) or dynamically assigned by the ISP each time the EMG1302-R10A tries to access the Internet. If your ISP assigns you a static WAN IP address, they should also assign you the subnet mask and DNS server IP address(es) (and a gateway IP address if you use the Ethernet or ENET ENCAP encapsulation method). DNS Server Address Assignment Use Domain Name System (DNS) 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 EMG1302-R10A can get the DNS server addresses in the following ways. 1 2 The ISP tells you the DNS server addresses, usually in the form of an information sheet, when you sign up. If your ISP gives you DNS server addresses, manually enter them in the DNS server fields. If your ISP dynamically assigns the DNS server IP addresses (along with the EMG1302-R10As WAN IP address), set the DNS server fields to get the DNS server address from the ISP. 56 EMG1302-R10A Users Guide Chapter 7 WAN WAN MAC Address The MAC address screen allows users to configure the WAN port's MAC address by either using the factory default or cloning the MAC address from a computer on your LAN. Choose Factory Default to select the factory assigned default MAC Address. Otherwise, click Clone the computer's MAC 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 configuration file. It is recommended that you clone the MAC address prior to hooking up the WAN Port. Maximum Transmission Unit A maximum transmission unit (MTU) is the largest size packet or frame, specified in octets (eight-

bit bytes) that can be sent in a packet- or frame-based network. The Transmission Control Protocol

(TCP) uses the MTU to determine the maximum size of each packet in any transmission. Too large an MTU size may mean retransmissions if the packet encounters a router that can't handle that large a packet. Too small an MTU size means relatively more header overhead and more acknowledgements that have to be sent and handled. 7.3.2 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. Figure 25 Multicast Example A B C D Server In the multicast example above, systems A and D comprise one multicast group. In multicasting, the server only needs to send one data stream and this is delivered to systems A and D. 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. The EMG1302-R10A supports both IGMP version 1 (IGMP-v1) and IGMP version 2 (IGMP-v2). At start up, the EMG1302-R10A queries all directly connected networks to gather group membership. After that, the EMG1302-R10A periodically updates this information. IP multicasting can be enabled/disabled on the EMG1302-R10A LAN and/or WAN interfaces in the Web Configurator

(LAN; WAN). Select None to disable IP multicasting on these interfaces. EMG1302-R10A Users Guide 57 Chapter 7 WAN Auto-IP-Change When the EMG1302-R10A gets a WAN IP address which is in the same subnet as the LAN IP address 192.168.1.1, Auto-IP-Change allows the EMG1302-R10A to change its LAN IP address to 10.0.0.1 automatically. If the EMG1302-R10As original LAN IP address is 10.0.0.1 and the WAN IP address is in the same subnet, such as 10.0.0.3, the EMG1302-R10A switches to use 192.168.1.1 as its LAN IP address. Figure 26 Auto-IP-Change LAN WAN 192.168.1.1 192.168.1.23 10.0.0.1 Auto-IP-Change only works under the following conditions:

The EMG1302-R10A must be in Router Mode (see Chapter 21 on page 158 for more information) for Auto-IP-Change to become active. The EMG1302-R10A is set to receive a dynamic WAN IP address using the Ethernet or PPPoE connection type. 58 EMG1302-R10A Users Guide 7.4 Management WAN Use this screen to view, change, or add your EMG1302-R10As Internet access settings.

EMG1302-R10A Users Guide 61 Chapter 7 WAN 7.4.1.1 PPPoE Encapsulation The EMG1302-R10A supports PPPoE (Point-to-Point Protocol over Ethernet). 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 EMG1302-R10A (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the EMG1302-R10A does that part of the task. Furthermore, with NAT, all of the LANs computers will have access. 62 EMG1302-R10A Users Guide This screen displays when you select PPP over Ethernet encapsulation.

See the appendices for more detailed information about wireless networks. The following figure provides an example of a wireless network. Figure 35 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 EMG1302-R10A is the AP. 8.2 What You Can Do Use the General screen to enter the SSID, select the channel, and configure wireless security

(Section 8.4 on page 78). Use the More AP screen to enable and configure multiple wireless networks (Section 8.6 on page 83) Use the MAC Filter screen to allow or deny wireless stations based on their MAC addresses from connecting to the EMG1302-R10A (Section 8.7 on page 85). Use the Advanced screen to allow intra-BSS network and set the RTS/CTS Threshold (Section 8.8 on page 86). EMG1302-R10A Users Guide 75 Chapter 8 Wireless LAN Use the QoS screen to ensure Quality of Service (QoS) in your wireless network (Section 8.9 on page 87). Use the WPS screen to quickly set up a wireless network with strong security, without having to configure security settings manually (Section 8.10 on page 88). Use the WPS Station screen to add a wireless station using WPS (Section 8.11 on page 89). Use the Scheduling screen to set the times your wireless LAN is turned on and off (Section 8.12 on page 90). Use the WDS screen to set up Wireless Distribution System (WDS) (Section 8.13 on page 91). 8.3 What You Should Know 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. 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. Wireless Security Overview The following sections introduce different types of wireless security you can set up in the wireless network. 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. 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 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. 76 EMG1302-R10A Users Guide Chapter 8 Wireless LAN 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. User Authentication You can make every user log in to the wireless network before they can use it. This is called user authentication. 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. 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. 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 page 77 for information about this.) Table 19 Types of Encryption for Each Type of Authentication Weakest NO AUTHENTICATION No Security Static WEP WPA-PSK RADIUS SERVER WPA Strongest WPA2-PSK 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. EMG1302-R10A Users Guide 77 Chapter 8 Wireless LAN 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. Note: It is recommended that wireless networks use WPA-PSK, WPA, or stronger encryption. IEEE 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. Note: 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. When you select WPA2-PSK in your EMG1302-R10A, 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 (depending on the type of wireless network login) and select the WPA Compatible option in the EMG1302-R10A. 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. WPS WiFi Protected Setup (WPS) is an industry standard specification, defined by the WiFi Alliance. WPS allows you to quickly set up a wireless network with strong security, without having to configure security settings manually. Depending on the devices in your network, you can either press a button (on the device itself, or in its configuration utility) or enter a PIN (Personal Identification Number) in the devices. Then, they connect and set up a secure network by themselves. See how to set up a secure wireless network using WPS in the Section 6.2 on page 43. 8.4 General Wireless LAN Screen Use this screen to configure the SSID of the wireless LAN and configure the wireless security mode. The screen varies depending on what you select in the Security Mode field. Note: If you are configuring the EMG1302-R10A from a computer connected to the wireless LAN and you change the EMG1302-R10As SSID, channel or security settings, you will lose your wireless connection when you press Apply to confirm. You must then change the wireless settings of your computer to match the EMG1302-R10As new settings. 78 EMG1302-R10A Users Guide Click Configuration > Network > Wireless LAN to open the General screen.

If Auto is selected, the EMG1302-R10A will use 40MHz if it is supported. A standard 20MHz channel offers transfer speeds of up to 150Mbps whereas a 40MHz channel uses two standard channels and offers speeds of up to 300 Mbps. 40MHz (channel bonding or dual channel) bonds two adjacent radio channels to increase throughput. The wireless clients must also support 40 MHz. It is often better to use the 20 MHz setting in a location where the environment hinders the wireless signal. Select 20MHz if you want to lessen radio interference with other wireless devices in your neighborhood or the wireless clients do not support channel bonding.

EMG1302-R10A Users Guide 101 Chapter 10 DHCP Server 102 EMG1302-R10A Users Guide CHAPTER 11 Quality of Service (QoS) 11.1 Overview Use the QoS screen to set up your EMG1302-R10A to use QoS for traffic management. Quality of Service (QoS) refers to both a networks ability to deliver data with minimum delay, and the networking methods used to control bandwidth. QoS allows the EMG1302-R10A to group and prioritize application traffic and fine-tune network performance. Without QoS, all traffic data are equally likely to be dropped when the network is congested. This can cause a reduction in network performance and make the network inadequate for time-critical applications such as video-on-demand. The EMG1302-R10A assigns each packet a priority and then queues the packet accordingly. Packets assigned with a high priority are processed more quickly than those with low priorities if there is congestion, allowing time-sensitive applications to flow more smoothly. Time-sensitive applications include both those that require a low level of latency (delay) and a low level of jitter (variations in delay) such as Voice over IP (VoIP) or Internet gaming, and those for which jitter alone is a problem such as Internet radio or streaming video. In the following figure, your Internet connection has an upstream transmission speed of 50 Mbps. You configure a classifier to assign the highest priority queue (6) to VoIP traffic from the LAN interface, so that voice traffic would not get delayed when there is network congestion. Traffic from the bosss IP address (192.168.1.23 for example) is mapped to queue 5. Traffic that does not match these two classes are assigned priority queue based on the internal QoS mapping table on the EMG1302-R10A. Figure 54 QoS Example VoIP: Queue 6 Boss: Queue 5 IP=192.168.1.23 DSL 50 Mbps EMG1302-R10A Users Guide 103 Chapter 11 Quality of Service (QoS) 11.1.1 What You Can Do in the QoS Screens Use the General screen (Section 11.2 on page 104) to enable QoS on the EMG1302-R10A, and specify the type of scheduling. Use the Rule-based QoS screen (Section 11.3 on page 105) to define and setup QoS-specific rules. 11.1.2 What You Need to Know About QoS 802.1p QoS is used to prioritize source-to-destination traffic flows. All packets in the same flow are given the same priority. 802.1p is a way of managing traffic in a network by grouping similar types of traffic together and treating each type as a class. You can use 802.1p to give different priorities to different packet types. Tagging and Marking In a QoS class, you can configure whether to add or change the DiffServ Code Point (DSCP) value and IEEE 802.1p priority level in a matched packet. When the packet passes through a compatible network, the networking device, such as a backbone switch, can provide specific treatment or service based on the tag or marker. Finding Out More See Section 11.4 on page 107 for advanced technical information on QoS. 11.2 The Quality of Service General Screen Use this screen to enable or disable QoS and set the upstream bandwidth. Click Configuration > Network > QoS > General to open the screen as shown next. Figure 55 Configuration > Network > QoS > General 104 EMG1302-R10A Users Guide Chapter 11 Quality of Service (QoS) The following table describes the labels in this screen. Table 36 Configuration > Network > QoS > General LABEL QoS Bandwidth of Upstream DESCRIPTION Select Enable or Disable to activate/disable the service. Enter the amount of upstream bandwidth for the WAN interfaces that you want to allocate using QoS. The recommendation is to set this speed to match the interfaces actual transmission speed. For example, set the WAN interfaces speed to 100000 kbps if your Internet connection has an upstream transmission speed of 100 Mbps. You can set this number higher than the interfaces actual transmission speed. The ZyXEL Device uses up to 95% of the DSL ports actual upstream transmission speed even if you set this number higher than the DSL ports actual transmission speed. You can also set this number lower than the interfaces actual transmission speed. This will cause the ZyXEL Device to not use some of the interfaces available bandwidth. If you leave this field blank, the ZyXEL Device automatically sets this number to be 95% of the WAN interfaces actual upstream transmission speed. Bandwidth of Downstream Enter the amount of downstream bandwidth for the LAN interfaces (including HPNA and WLAN) that you want to allocate using QoS. The recommendation is to set this speed to match the WAN interfaces actual transmission speed. For example, set the LAN managed downstream bandwidth to 100000 kbps if you use a 100 Mbps wired Ethernet WAN connection. You can also set this number lower than the WAN interfaces actual transmission speed. This will cause the ZyXEL Device to not use some of the interfaces available bandwidth. If you leave this field blank, the ZyXEL Device automatically sets this to the LAN interfaces maximum supported connection speed. Select Enable or Disable to activate/disable the service.

The following table describes the traffic types defined in the IEEE 802.1d standard (which incorporates the 802.1p). Table 39 IEEE 802.1p Priority Level and Traffic Type PRIORITY LEVEL Level 7 Level 6 TRAFFIC TYPE Typically used for network control traffic such as router configuration messages. Typically used for voice traffic that is especially sensitive to jitter (jitter is the variations in delay). Typically used for video that consumes high bandwidth and is sensitive to jitter. Typically used for controlled load, latency-sensitive traffic such as SNA (Systems Network Architecture) transactions. Typically used for excellent effort or better than best effort and would include important business traffic that can tolerate some delay. This is for spare bandwidth. 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. Typically used for best-effort traffic. Level 5 Level 4 Level 3 Level 2 Level 1 Level 0 11.4.2 IP Precedence Similar to IEEE 802.1p prioritization at layer-2, you can use IP precedence to prioritize packets in a layer-3 network. IP precedence uses three bits of the eight-bit ToS (Type of Service) field in the IP header. There are eight classes of services (ranging from zero to seven) in IP precedence. Zero is the lowest priority level and seven is the highest. 11.4.3 Automatic Priority Queue Assignment If you enable QoS on the EMG1302-R10A, the EMG1302-R10A can automatically base on the IEEE 802.1p priority level, IP precedence and/or packet length to assign priority to traffic which does not match a class. EMG1302-R10A Users Guide 107 Chapter 11 Quality of Service (QoS) The following table shows you the internal layer-2 and layer-3 QoS mapping on the EMG1302-

R10A. On the EMG1302-R10A, traffic assigned to higher priority queues gets through faster while traffic in lower index queues is dropped if the network is congested. Table 40 Internal Layer2 and Layer3 QoS Mapping PRIORITY QUEUE 0 1 2 3 4 5 6 7 LAYER 2 IEEE 802.1P USER PRIORITY

For example, the source address of an outgoing packet, used within one network is changed to a different IP address known within another network. The figure below is a simple illustration of a NAT network. You want to assign ports 21-25 to one, 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 to the devices (A to D) connected to your EMG1302-R10A. The ISP assigns the WAN IP address. The NAT network appears as a single host on the Internet. All traffic coming from A to D going out to the Internet use the IP address of the EMG1302-R10A, which is 192.168.1.1. Figure 58 NAT Example A: 192.168.1.33

, Telnet, SNMP Ports 21 to 25 B: 192.168.1.34 Port 80 C: 192.168.1.35 LAN WAN 192.168.1.1 IP address assigned by ISP This chapter discusses how to configure NAT on the EMG1302-R10A. Note: You must create a firewall rule in addition to setting up NAT, to allow traffic from the WAN to be forwarded through the EMG1302-R10A. 12.2 What You Can Do Use the General screen to enable NAT (Section 12.4 on page 112). EMG1302-R10A Users Guide 109 Chapter 12 NAT Use the Port Forwarding screen to change your EMG1302-R10As port forwarding settings

Inside/Outside This denotes where a host is located relative to the EMG1302-R10A, for example, the computers of your subscribers are the inside hosts, while the web servers on the Internet are the outside hosts. Global/Local This denotes the IP address of a host in a packet as the packet traverses a router, for example, the local address refers to the IP address of a host when the packet is in the local network, while the global address refers to the IP address of the host when the same packet is traveling in the WAN side. Note: Inside/outside refers to the location of a host, while global/local refers to the IP address of a host used in a packet. An inside local address (ILA) is the IP address of an inside host in a packet when the packet is still in the local network, while an inside global address (IGA) is the IP address of the same inside host when the packet is on the WAN side. The following table summarizes this information. Table 41 NAT Definitions ITEM Inside Outside Local Global DESCRIPTION This refers to the host on the LAN. This refers to the host on the WAN. This refers to the packet address (source or destination) as the packet travels on the LAN. This refers to the packet address (source or destination) as the packet travels on the WAN. Note: NAT never changes the IP address (either local or global) of an outside host. What NAT Does In the simplest form, NAT changes the source IP address in a packet received from a subscriber

(the inside local address) to another (the inside global address) before forwarding the packet to the WAN side. When the response comes back, NAT translates the destination address (the inside 110 EMG1302-R10A Users Guide Chapter 12 NAT global address) back to the inside local address before forwarding it to the original inside host. Note that the IP address (either local or global) of an outside host is never changed. The global IP addresses for the inside hosts can be either static or dynamically assigned by the ISP. In addition, you can designate servers, for example, a web server and a telnet server, on your local network and make them accessible to the outside world. If you do not define any servers, NAT offers the additional benefit of firewall protection. With no servers defined, your EMG1302-R10A filters out all incoming inquiries, thus preventing intruders from probing your network. For more information on IP address translation, refer to RFC 1631, The IP Network Address Translator (NAT). How NAT Works Each packet has two addresses a source address and a destination address. For outgoing packets, the ILA (Inside Local Address) is the source address on the LAN, and the IGA (Inside Global Address) is the source address on the WAN. For incoming packets, the ILA is the destination address on the LAN, and the IGA is the destination address on the WAN. NAT maps private (local) IP addresses to globally unique ones required for communication with hosts on other networks. It replaces the original IP source address in each packet and then forwards it to the Internet. The EMG1302-R10A keeps track of the original addresses and port numbers so incoming reply packets can have their original values restored. The following figure illustrates this. Figure 59 How NAT Works EMG1302-R10A Users Guide 111 Chapter 12 NAT 12.4 The NAT General Screen Use this screen to enable NAT and set a default server.

Click Cancel to begin configuring this screen afresh. 12.6 The NAT Trigger Port Screen Some services use a dedicated range of ports on the client side and a dedicated range of ports on the server side. With regular port forwarding you set a forwarding port in NAT to forward a service

(coming in from the server on the WAN) to the IP address of a computer on the client side (LAN). The problem is that port forwarding only forwards a service to a single LAN IP address. In order to use the same service on a different LAN computer, you have to manually replace the LAN computers IP address in the forwarding port with another LAN computers IP address. Trigger port forwarding solves this problem by allowing computers on the LAN to dynamically take turns using the service. The EMG1302-R10A 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 EMG1302-R10A WAN port receives a response with a specific port number and protocol

(open port), the EMG1302-R10A 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.

Each remote node specifies only the network to which the gateway is directly connected, and the EMG1302-R10A has no knowledge of the networks beyond. For instance, the EMG1302-R10A knows about network N2 in the following figure through remote node Router 1. However, the EMG1302-R10A 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 1 (via gateway Router 2). The static routes are for you to tell the EMG1302-R10A about the networks beyond the remote nodes.

Enable the firewall to protect your LAN computers from attacks by hackers on the Internet and control access between the LAN and WAN. By default the firewall:

allows traffic that originates from your LAN computers to go to all of the networks. blocks traffic that originates on the other networks from going to the LAN. The following figure illustrates the default firewall action. User A can initiate an IM (Instant Messaging) session from the LAN to the WAN (1). Return traffic for this session is also allowed (2). However other traffic initiated from the WAN is blocked (3 and 4).

EMG1302-R10A Users Guide 125 Chapter 16 Security 16.3 What You Need To Know The following terms and concepts may help as you read through this chapter. What is a Firewall?

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. 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. About the EMG1302-R10A Firewall The EMG1302-R10As firewall feature physically separates the LAN and the WAN and acts as a secure gateway for all data passing between the networks. It 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 EMG1302-R10A's purpose is to allow a private Local Area Network (LAN) to be securely connected to the Internet. The EMG1302-R10A can be used to prevent theft, destruction and modification of data, as well as log events, which may be important to the security of your network. The EMG1302-R10A 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 EMG1302-R10A 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, and the World Wide Web. However, "inbound access" is not allowed (by default) unless the remote host is authorized to use a specific service. 126 EMG1302-R10A Users Guide Chapter 16 Security Guidelines For Enhancing Security With Your Firewall Change the default password via Web Configurator. Think about access control before you connect to the network in any way, including attaching a modem to the port. Limit who can access your router. 1 2 3 4 Don't enable any local service (such as 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 6 7 For local services that are enabled, protect against misuse. Protect by configuring the services to communicate only with specific peers, and protect by configuring rules to block packets for the services at specific interfaces. Protect against IP spoofing by making sure the firewall is active. Keep the firewall in a secured (locked) room. 16.4 The Firewall General Screen Use this screen to enable or disable the EMG1302-R10As firewall, and set up firewall logs.

EMG1302-R10A Users Guide 129 Chapter 16 Security 130 EMG1302-R10A Users Guide CHAPTER 17 Content Filtering 17.1 Overview This chapter provides a brief overview of content filtering using the embedded web GUI. Internet content filtering allows you to create and enforce Internet access policies tailored to your needs. Content filtering is the ability to block certain web features or specific URL keywords. 17.2 What You Need To Know The following terms and concepts may help as you read through this chapter. Content Filtering Profiles Content filtering allows you to block certain web features, such as cookies, and/or block access to specific web sites. For example, you can configure one policy that blocks John Does access to arts and entertainment web pages. A content filtering profile conveniently stores your custom settings for the following features. Keyword Blocking URL Checking The EMG1302-R10A checks the URLs domain name (or IP address) and file path separately when performing keyword blocking. The URLs domain name or IP address is the characters that come before the first slash in the URL. For example, with the URL www.zyxel.com.tw/news/pressroom.php, the domain name is www.zyxel.com.tw. The file path is the characters that come after the first slash in the URL. For example, with the URL www.zyxel.com.tw/news/pressroom.php, the file path is news/pressroom.php. Since the EMG1302-R10A checks the URLs domain name (or IP address) and file path separately, it will not find items that go across the two. For example, with the URL www.zyxel.com.tw/news/

pressroom.php, the EMG1302-R10A would find tw in the domain name (www.zyxel.com.tw). It would also find news in the file path (news/pressroom.php) but it would not find tw/news.

Your EMG1302-R10A supports SNMP agent functionality, which allows a manager station to manage and monitor the EMG1302-R10A through the network. The EMG1302-

R10A supports SNMP version one (SNMPv1) and version two (SNMPv2c). The next figure illustrates an SNMP management operation. Figure 78 SNMP Management Model An SNMP managed network consists of two main types of component: agents and a manager. An agent is a management software module that resides in a managed device (the EMG1302-

R10A). An agent translates the local management information from the managed device into a form compatible with SNMP. The manager is the console through which network administrators perform network management functions. It executes applications that control and monitor managed devices. The managed devices contain object variables/managed objects that define each piece of information to be collected about a device. Examples of variables include such as number of packets received, node port status etc. A Management Information Base (MIB) is a collection of managed objects. SNMP allows a manager and agents to communicate for the purpose of accessing these objects. SNMP itself is a simple request/response protocol based on the manager/agent model. The manager issues a request and the agent returns responses using the following protocol operations:

Get - Allows the manager to retrieve an object variable from the agent. GetNext - Allows the manager to retrieve the next object variable from a table or list within an agent. In SNMPv1, when a manager wants to retrieve all elements of a table from an agent, it initiates a Get operation, followed by a series of GetNext operations. Set - Allows the manager to set values for object variables within an agent. Trap - Used by the agent to inform the manager of some events. 140 EMG1302-R10A Users Guide Chapter 19 Remote Management To change your EMG1302-R10As SNMP settings, click Configuration > Management > Remote MGMT > SNMP to display the screen as shown.

Universal Plug and Play (UPnP) is a distributed, open networking standard that uses TCP/IP for simple peer-to-peer network connectivity between devices. 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. 20.2 What You Need to Know 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. 20.2.1 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. 20.2.2 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. When a UPnP device joins a network, it announces its presence with a multicast message. For security reasons, the EMG1302-R10A allows multicast messages on the LAN only. EMG1302-R10A Users Guide 145 Chapter 20 Universal Plug-and-Play (UPnP) All UPnP-enabled devices may communicate freely with each other without additional configuration.

If you changed the IP address and have forgotten it, you might get the IP address of the EMG1302-

R10A by looking up the IP address of the default gateway for your computer. To do this in most Windows computers, click Start > Run, enter cmd, and then enter ipconfig. The IP address of the Default Gateway might be the IP address of the EMG1302-R10A (it depends on the network), so enter this IP address in your Internet browser.Set your device to Router Mode, login (see the Quick Start Guide for instructions) and go to the Device Information table in the Status screen. Your EMG1302-R10As IP address is available in the Device Information table. If the DHCP setting under LAN information is None, your device has a fixed IP address. If the DHCP setting under LAN information is Client, then your device receives an IP address from a DHCP server on the network. If your EMG1302-R10A is a DHCP client, you can find your IP address from the DHCP server. This information is only available from the DHCP server which allocates IP addresses on your network. Find this information directly from the DHCP server or contact your system administrator for more information. Reset your EMG1302-R10A to change all settings back to their default. This means your current settings are lost. See Section 22.5 on page 164 in the Troubleshooting for information on resetting your EMG1302-R10A. I forgot the username and password. 1 2 The default username is admin and password is 1234. If this does not work, you have to reset the device to its factory defaults. See Section 22.5 on page 164. I cannot see or access the Login screen in the Web Configurator. 1 Make sure you are using the correct IP address. The default IP address is 192.168.1.1.

Advanced Suggestions Try to access the EMG1302-R10A using another service, such as Telnet. If you can access the EMG1302-R10A, check the remote management settings and firewall rules to find out why the EMG1302-R10A does not respond to HTTP. If your computer is connected to the WAN port or is connected wirelessly, use a computer that is connected to a LAN/ETHERNET port. I can see the Login screen, but I cannot log in to the EMG1302-R10A. 1 Make sure you have entered the password correctly. The default password is 1234. This field is case-sensitive, so make sure [Caps Lock] is not on. 2 3 You cannot log in to the Web Configurator while someone is using Telnet to access the EMG1302-

R10A. Log out of the EMG1302-R10A in the other session, or ask the person who is logged in to log out. This can happen when you fail to log out properly from your last session. Try logging in again after 5 minutes. 4 Disconnect and re-connect the power adaptor or cord to the EMG1302-R10A. 5 If this does not work, you have to reset the device to its factory defaults. See Section 22.5 on page 164. 22.4 Internet Access I cannot access the Internet. EMG1302-R10A Users Guide 163 Chapter 22 Troubleshooting 1 2 Check the hardware connections, and make sure the LEDs are behaving as expected. See the Quick Start Guide. If you are trying to access the Internet wirelessly, make sure the wireless settings in the wireless client are the same as the settings in the AP. 3 Disconnect all the cables from your device, and follow the directions in the Quick Start Guide again. 4 Go to Maintenance > Sys OP Mode. Check your Configuration Mode setting. Select Router Mode if your device routes traffic between a local network and another network such as the Internet. Select Access Point if your device bridges traffic between clients on the same network. 5 If the problem continues, contact your ISP. I cannot access the Internet anymore. I had access to the Internet (with the EMG1302-

R10A), but my Internet connection is not available anymore. 1 2 3 Check the hardware connections, and make sure the LEDs are behaving as expected. See the Quick Start Guide and Section 1.5 on page 16. Reboot the EMG1302-R10A. If the problem continues, contact your ISP. The Internet connection is slow or intermittent. 1 2 3 4 There might be a lot of traffic on the network. Look at the LEDs, and check Section 1.5 on page 16. If the EMG1302-R10A is sending or receiving a lot of information, try closing some programs that use the Internet, especially peer-to-peer applications. Check the signal strength. If the signal strength is low, try moving the EMG1302-R10A closer to the AP if possible, and look around to see if there are any devices that might be interfering with the wireless network (for example, microwaves, other wireless networks, and so on). Reboot the EMG1302-R10A. If the problem continues, contact the network administrator or vendor, or try one of the advanced suggestions. 22.5 Resetting the EMG1302-R10A to Its Factory Defaults If you reset the EMG1302-R10A, you lose all of the changes you have made. The EMG1302-R10A re-loads its default settings, and the password resets to 1234. You have to make all of your changes again. 164 EMG1302-R10A Users Guide Chapter 22 Troubleshooting You will lose all of your changes when you push the RESET button. To reset the EMG1302-R10A:

1 Make sure the power LED is on. 2 3 Press the RESET button for longer than 1 second to restart/reboot the EMG1302-R10A. Press the RESET button for longer than five seconds to set the EMG1302-R10A back to its factory-

default configurations. If the EMG1302-R10A restarts automatically, wait for the EMG1302-R10A to finish restarting, and log in to the Web Configurator. The password is 1234. If the EMG1302-R10A does not restart automatically, disconnect and reconnect the EMG1302-

R10As power. Then, follow the directions above again. 22.6 Wireless Router/AP Troubleshooting I cannot access the EMG1302-R10A or ping any computer from the WLAN (wireless AP or router). 1 Make sure the wireless LAN is enabled on the EMG1302-R10A. 2 Make sure the wireless adapter on the wireless station is working properly. 3 Make sure the wireless adapter installed on your computer is IEEE 802.11 compatible and supports the same wireless standard as the EMG1302-R10A. 4 Make sure your computer (with a wireless adapter installed) is within the transmission range of the EMG1302-R10A. 5 Check that both the EMG1302-R10A and your wireless station are using the same wireless and wireless security settings. 6 Make sure traffic between the WLAN and the LAN is not blocked by the firewall on the EMG1302-

R10A. 7 Make sure you allow the EMG1302-R10A to be remotely accessed through the WLAN interface. Check your remote management settings. See the chapter on Wireless LAN in the Users Guide for more information. I set up URL keyword blocking, but I can still access a website that should be blocked. EMG1302-R10A Users Guide 165 Chapter 22 Troubleshooting Make sure that you select the Enable URL Keyword Blocking check box in the Content Filtering screen. Make sure that the keywords that you type are listed in the Keyword List. I can access the Internet, but I cannot open my network folders. Make sure your account has access rights to the folder you are trying to open. I cannot access the Web Configurator after I switched to AP mode. When you change from router mode to AP mode, your computer must have an IP address in the range between 192.168.1.3 and 192.168.1.254. Refer to Appendix C on page 193 for instructions on how to change your computers IP address. What factors may cause intermittent or unstabled wireless connection? How can I solve this problem?

The following factors may cause interference:

Obstacles: walls, ceilings, furniture, and so on. Building Materials: metal doors, aluminum studs. Electrical devices: microwaves, monitors, electric motors, cordless phones, and other wireless devices. To optimize the speed and quality of your wireless connection, you can:

Move your wireless device closer to the AP if the signal strength is low. Reduce wireless interference that may be caused by other wireless networks or surrounding wireless electronics such as cordless phones. Place the AP where there are minimum obstacles (such as walls and ceilings) between the AP and the wireless client. Reduce the number of wireless clients connecting to the same AP simultaneously, or add additional APs if necessary. Try closing some programs that use the Internet, especially peer-to-peer applications. If the wireless client is sending or receiving a lot of information, it may have too many programs open that use the Internet. Position the antenna for best reception. If the AP is placed on a table or floor, point the antenna upwards. If the AP is placed at a high position, point the antenna downwards. Try pointing the antenna in different directions and check which provides the strongest signal to the wireless clients. 166 EMG1302-R10A Users Guide APPENDIX A Customer Support In the event of problems that cannot be solved by using this manual, you should contact your vendor.

Ad-hoc Wireless LAN Configuration The simplest WLAN configuration is an independent (Ad-hoc) WLAN that connects a set of computers with wireless adapters (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 112 Peer-to-Peer Communication in an Ad-hoc Network BSS A Basic Service Set (BSS) exists when all communications between wireless clients or between a wireless client and a wired network client go through one access point (AP). Intra-BSS traffic is traffic between wireless clients in the BSS. When Intra-BSS is enabled, wireless client A and B can access the wired network and communicate with each other. When Intra-BSS is EMG1302-R10A Users Guide 185 Appendix C Wireless LANs disabled, wireless client A and B can still access the wired network but cannot communicate with each other. Figure 113 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. 186 EMG1302-R10A Users Guide An ESSID (ESS IDentification) uniquely identifies each ESS. All access points and their associated wireless clients within the same ESS must have the same ESSID in order to communicate. Figure 114 Infrastructure WLAN Appendix C Wireless LANs Channel RTS/CTS A channel is the radio frequency(ies) used by wireless devices to transmit and receive data. Channels available depend on your geographical area. You may have a choice of channels (for your region) so you should use a channel different from 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. 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 EMG1302-R10A Users Guide 187 Appendix C Wireless LANs 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. Figure 115 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. Note: 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. 188 EMG1302-R10A Users Guide 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. Appendix C Wireless LANs Preamble Type Preamble is used to signal that data is coming to the receiver. Short and long refer to the length of the synchronization field in a packet. Short preamble increases performance as less time sending preamble means more time for sending data. All IEEE 802.11 compliant wireless adapters support long preamble, but not all support short preamble. Use long preamble if you are unsure what preamble mode other wireless devices on the network support, and to provide more reliable communications in busy wireless networks. Use short preamble if you are sure all wireless devices on the network support it, and to provide more efficient communications. Use the dynamic setting to automatically use short preamble when all wireless devices on the network support it, otherwise the EMG1302-R10A uses long preamble. Note: The wireless devices 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:

54 DBPSK (Differential Binary Phase Shift Keyed) DQPSK (Differential Quadrature Phase Shift Keying) CCK (Complementary Code Keying) OFDM (Orthogonal Frequency Division Multiplexing) Wireless Security Overview Wireless security is vital to your network to protect wireless communication between wireless clients, access points and the wired network. Wireless security methods available on the EMG1302-R10A are data encryption, wireless client authentication, restricting access by device MAC address and hiding the EMG1302-R10A identity. EMG1302-R10A Users Guide 189 Appendix C Wireless LANs The following figure shows the relative effectiveness of these wireless security methods available on your EMG1302-R10A. Table 68 Wireless Security Levels SECURITY LEVEL Least Secure SECURITY TYPE Unique SSID (Default) Unique SSID with Hide SSID Enabled MAC Address Filtering WEP Encryption IEEE EAP with RADIUS Server Authentication Wi-Fi Protected Access (WPA) WPA2 Most Secure Note: You must enable the same wireless security settings on the EMG1302-R10A and on all wireless clients that you want to associate with it. In June 2001, the IEEE 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 are:

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 clients. IEEE 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 client and the network RADIUS server. 190 EMG1302-R10A Users Guide Types of RADIUS Messages The following types of RADIUS messages are exchanged between the access point and the RADIUS server for user authentication:

Appendix C Wireless LANs 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. 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 EAP Authentication This section discusses some popular authentication types: EAP-MD5, EAP-TLS, EAP-TTLS, PEAP and LEAP. Your wireless LAN device may not support all authentication types. EAP (Extensible Authentication Protocol) is an authentication protocol that runs on top of the IEEE transport mechanism in order to support multiple types of user authentication. By using EAP to interact with an EAP-compatible RADIUS server, an access point helps a wireless station and a RADIUS server perform authentication. The type of authentication you use depends on the RADIUS server and an intermediary AP(s) that supports IEEE. For EAP-TLS authentication type, you must first have a wired connection to the network and obtain the certificate(s) from a certificate authority (CA). A certificate (also called digital IDs) can be used to authenticate users and a CA issues certificates and guarantees the identity of each certificate owner. EAP-MD5 (Message-Digest Algorithm 5) MD5 authentication is the simplest one-way authentication method. The authentication server sends a challenge to the wireless client. The wireless client proves that it knows the password by EMG1302-R10A Users Guide 191 Appendix C Wireless LANs 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 clients 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. 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. 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 security configuration screen. You may still configure and store keys, but they will not be used while dynamic WEP is enabled. Note: EAP-MD5 cannot be used with Dynamic WEP Key Exchange 192 EMG1302-R10A Users Guide 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. Appendix C Wireless LANs Table 69 Comparison of EAP Authentication Types EAP-TLS Yes Yes Yes Yes Strong Hard No 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-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 and WPA2 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. Key differences between WPA or WPA2 and WEP are improved data encryption and user authentication. 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. Encryption WPA improves data encryption by using Temporal Key Integrity Protocol (TKIP), Message Integrity Check (MIC) and IEEE. WPA2 also uses TKIP when required for compatibility reasons, but offers stronger encryption than TKIP with Advanced Encryption Standard (AES) in the Counter mode with Cipher block chaining Message authentication code Protocol (CCMP). TKIP uses 128-bit keys that are dynamically generated and distributed by the authentication server. AES (Advanced Encryption Standard) is a block cipher that uses a 256-bit mathematical algorithm called Rijndael. They both include 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. WPA and WPA2 regularly change and rotate the encryption keys so that the same encryption key is never used twice. EMG1302-R10A Users Guide 193 Appendix C Wireless LANs 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 PMK 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. 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), with TKIP and AES it is more difficult to decrypt data on a Wi-Fi network than WEP and difficult for an intruder to break into the network. The encryption mechanisms used for WPA(2) and WPA(2)-PSK are the same. The only difference between the two is that WPA(2)-PSK uses a simple common password, instead of user-specific credentials. The common-password approach makes WPA(2)-PSK susceptible to brute-force password-guessing attacks but its still an improvement over WEP as it employs a consistent, single, alphanumeric password to derive a PMK which is used to generate unique temporal encryption keys. This prevent all wireless devices sharing the same encryption keys. (a weakness of WEP) User Authentication WPA and WPA2 apply IEEE and Extensible Authentication Protocol (EAP) to authenticate wireless clients using an external RADIUS database. WPA2 reduces the number of key exchange messages from six to four (CCMP 4-way handshake) and shortens the time required to connect to a network. Other WPA2 authentication features that are different from WPA include key caching and pre-

authentication. These two features are optional and may not be supported in all wireless devices. Key caching allows a wireless client to store the PMK it derived through a successful authentication with an AP. The wireless client uses the PMK when it tries to connect to the same AP and does not need to go with the authentication process again. Pre-authentication enables fast roaming by allowing the wireless client (already connecting to an AP) to perform IEEE authentication with another AP before connecting to it. Wireless Client WPA Supplicants A wireless client supplicant is the software that runs on an operating system instructing the wireless client how to use WPA. At the time of writing, the most widely available supplicant is the WPA patch for Windows XP, Funk Software's Odyssey client. The Windows XP patch is a free download that adds WPA capability to Windows XP's built-in "Zero Configuration" wireless client. However, you must run Windows XP to use it. WPA(2) with RADIUS Application Example To set up WPA(2), 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. 194 EMG1302-R10A Users Guide Appendix C Wireless LANs 2 3 4 The RADIUS server then checks the user's identification against its database and grants or denies network access accordingly. A 256-bit Pairwise Master Key (PMK) is derived from the authentication process by the RADIUS server and the client. The RADIUS server distributes the PMK to the AP. The AP then sets up a key hierarchy and management system, using the PMK to dynamically generate unique data encryption keys. The keys are used to encrypt every data packet that is wirelessly communicated between the AP and the wireless clients. Figure 116 WPA(2) with RADIUS Application Example WPA(2)-PSK Application Example A WPA(2)-PSK application looks as follows. 1 2 3 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 or 64 hexadecimal characters (including spaces and symbols). The AP checks each wireless client's password and allows it to join the network only if the password matches. The AP and wireless clients generate a common PMK (Pairwise Master Key). The key itself is not sent over the network, but is derived from the PSK and the SSID. EMG1302-R10A Users Guide 195 Appendix C Wireless LANs 4 The AP and wireless clients use the TKIP or AES encryption process, the PMK and information exchanged in a handshake to create temporal encryption keys. They use these keys to encrypt data exchanged between them. Figure 117 WPA(2)-PSK Authentication Security Parameters Summary Refer to this table to see what other security parameters you should configure for each authentication method or key management protocol type. MAC address filters are not dependent on how you configure these security features.

A transmitter within a wireless device sends an RF signal to the antenna, which propagates the signal through the air. The antenna also operates in reverse by capturing RF signals from the air. Positioning the antennas properly increases the range and coverage area of a wireless LAN. Antenna Characteristics Frequency An antenna in the frequency of 2.4GHz (IEEE 802.11b and IEEE 802.11g) or 5GHz (IEEE 802.11a) is needed to communicate efficiently in a wireless LAN Radiation Pattern A radiation pattern is a diagram that allows you to visualize the shape of the antennas coverage area. Antenna Gain Antenna gain, measured in dB (decibel), is the increase in coverage within the RF beam width. Higher antenna gain improves the range of the signal for better communications. For an indoor site, each 1 dB increase in antenna gain results in a range increase of approximately 2.5%. For an unobstructed outdoor site, each 1dB increase in gain results in a range increase of approximately 5%. Actual results may vary depending on the network environment. Antenna gain is sometimes specified in dBi, which is how much the antenna increases the signal power compared to using an isotropic antenna. An isotropic antenna is a theoretical perfect antenna that sends out radio signals equally well in all directions. dBi represents the true gain that the antenna provides. Types of Antennas for WLAN There are two types of antennas used for wireless LAN applications. Omni-directional antennas send the RF signal out in all directions on a horizontal plane. The coverage area is torus-shaped (like a donut) which makes these antennas ideal for a room environment. With a wide coverage area, it is possible to make circular overlapping coverage areas with multiple access points. Directional antennas concentrate the RF signal in a beam, like a flashlight does with the light from its bulb. The angle of the beam determines the width of the coverage pattern. Angles typically range from 20 degrees (very directional) to 120 degrees (less directional). Directional antennas are ideal for hallways and outdoor point-to-point applications. EMG1302-R10A Users Guide 197 Appendix C Wireless LANs Positioning Antennas In general, antennas should be mounted as high as practically possible and free of obstructions. In point-topoint application, position both antennas at the same height and in a direct line of sight to each other to attain the best performance. For omni-directional antennas mounted on a table, desk, and so on, point the antenna up. For omni-directional antennas mounted on a wall or ceiling, point the antenna down. For a single AP application, place omni-directional antennas as close to the center of the coverage area as possible. For directional antennas, point the antenna in the direction of the desired coverage area. 198 EMG1302-R10A Users Guide APPENDIX D Common Services The following table lists some commonly-used services and their associated protocols and port numbers.
