These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communica-tions. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures: Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. To assure continued compliance, any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. (Example - use only shielded interface cables when connecting to computer or peripheral devices). FCC Radiation Exposure Statement This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20 centimeters between the radiator and your body. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operation.

The antennas used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter. Channel The Wireless Channel sets the radio frequency used for communication. •Access Points use a fixed Channel. You can select the Channel used. This allows you to choose a Channel which provides the least interference and best performance. In the USA and Canada, 11 channel are available. If using multiple Access Points, it is better if adjacent Access Points use different Channels to reduce interference. • In "Infrastructure" mode, Wireless Stations normally scan all Channels, looking for an Access Point. If more than one Access Point can be used, the one with the strongest signal is used. (This can only happen within an ESS.) • If using "Ad-hoc" mode (no Access Point), all Wireless stations should be set to use the same Channel. However, most Wireless stations will still scan all Channels to see if there is an existing "Ad-hoc" group they can join.

1 Chapter 1 Introduction This Chapter provides an overview of the Wireless ADSL Router's features and capabilities. Congratulations on the purchase of your new Wireless ADSL Router. The Wireless ADSL Router is a multi-function device providing the following services: • ADSL Modem. • Shared Broadband Internet Access for all LAN users. • Wireless Access Point for 802.11b and 802.11g Wireless Stations. • 4-Port Switching Hub for 10BaseT or 100BaseT connections. Figure 1: Wireless ADSL Router Wireless ADSL Router Features The Wireless ADSL Router incorporates many advanced features, carefully designed to provide sophisticated functions while being easy to use. Internet Access Features • Shared Internet Access. All users on the LAN or WLAN can access the Internet through the Wireless ADSL Router, using only a single external IP Address. The local (invalid) IP Addresses are hidden from external sources. This process is called NAT (Network Address Translation). • Built-in ADSL Modem. The Wireless ADSL Router has a built-in ADSL modem, supporting all common ADSL connections. • IPoA, PPPoE, PPPoA, Direct Connection Support. The Wireless ADSL Router supports all common connection methods. 1
Wireless ADSL Router User Guide 2 • Auto-detection of Internet Connection Method. The Wireless ADSL Router can test your ADSL and Internet connection to determine the connection method used by your ISP. • Fixed or Dynamic IP Address. On the Internet (WAN port) connection, the Wireless ADSL Router supports both Dynamic IP Address (IP Address is allocated on connection) and Fixed IP Address. Advanced Internet Functions • Application Level Gateways (ALGs). Applications which use non-standard connections or port numbers are normally blocked by the Firewall. The ability to define and allow such applications is provided, to enable such applications to be used normally. • Virtual Servers. This feature allows Internet users to access Internet servers on your LAN. The required setup is quick and easy. • URL Filter. Use the URL Filter to block access to undesirable Web sites by LAN users. • Logs. Define what data is recorded in the Logs, and optionally send log data to a Syslog Server. Log data can also be E-mailed to you. • Firewall. As well as the built-in firewall to protect your LAN, you can define Firewall Rules to determine which incoming and outgoing traffic should be permitted. • Dynamic DNS Support. DDNS, when used with the Virtual Servers feature, allows users to connect to Servers on your LAN using a Domain Name, even if you have a dynamic IP address which changes every time you connect. • VPN Pass through Support. PCs with VPN (Virtual Private Networking) software using PPTP, L2TP and IPSec are transparently supported - no configuration is required. Wireless Features • Standards Compliant. The Wireless ADSL Router complies with the IEEE802.11g (DSSS) specifications for Wireless LANs. • Supports both 802.11b and 802.11g Wireless Stations. The 802.11g standard provides for backward compatibility with the 802.11b standard, so both 802.11b and 802.11g Wireless stations can be used simultaneously. • Speeds to 54Mbps. All speeds up to the 802.11g maximum of 54Mbps are supported. • WEP support. Support for WEP (Wired Equivalent Privacy) is included. Key sizes of 64 Bit and 128 Bit are supported. • Wireless MAC Access Control. The Wireless Access Control feature can check the MAC address (hardware address) of Wireless stations to ensure that only trusted Wireless Stations can access your LAN. • Simple Configuration. If the default settings are unsuitable, they can be changed quickly and easily. LAN Features • 4-Port Switching Hub. The Wireless ADSL Router incorporates a 4-port 10/100BaseT switching hub, making it easy to create or extend your LAN. • DHCP Server Support. Dynamic Host Configuration Protocol provides a dynamic IP address to PCs and other devices upon request. The Wireless ADSL Router can act as a DHCP Server for devices on your local LAN and WLAN. • Multi Segment LAN Support. LANs containing one or more segments are supported, via the Wireless ADSL Router's RIP (Routing Information Protocol) support and built-in static routing table.
Introduction 3 Configuration & Management • Easy Setup. Use your WEB browser from anywhere on the LAN or WLAN for configuration. • Configuration File Upload/Download. Save (download) the configuration data from the Wireless ADSL Router to your PC, and restore (upload) a previously-saved configuration file to the Wireless ADSL Router. • Remote Management. The Wireless ADSL Router can be managed from any PC on your LAN. And, if the Internet connection exists, it can also (optionally) be configured via the Internet. • Network Diagnostics. You can use the Wireless ADSL Router to perform a Ping or DNS lookup. Security Features • Password - protected Configuration. Optional password protection is provided to prevent unauthorized users from modifying the configuration data and settings. • Wireless LAN Security. WEP (Wired Equivalent Privacy) is supported, as well as Wireless access control to prevent unknown wireless stations from accessing your LAN. • NAT Protection. An intrinsic side effect of NAT (Network Address Translation) technology is that by allowing all LAN users to share a single IP address, the location and even the existence of each PC is hidden. From the external viewpoint, there is no network, only a single device - the Wireless ADSL Router. • Firewall. All incoming data packets are monitored and all incoming server requests are filtered, thus protecting your network from malicious attacks from external sources. • Protection against DoS attacks. DoS (Denial of Service) attacks can flood your Internet connection with invalid packets and connection requests, using so much bandwidth and so many resources that Internet access becomes unavailable. The Wireless ADSL Router incorporates protection against DoS attacks. Package Contents The following items should be included: • The Wireless ADSL Router Unit • Power Adapter • Quick Installation Guide • CD-ROM containing the on-line manual. If any of the above items are damaged or missing, please contact your dealer immediately.

Setup 13 LAN Screen Use the LAN link on the main menu to reach the LAN screen An example screen is shown below. Figure 6: LAN Screen Data - LAN Screen TCP/IP IP Address IP address for the Wireless ADSL Router, as seen from the local LAN. Use the default value unless the address is already in use or your LAN is using a different IP address range. In the latter case, enter an unused IP Address from within the range used by your LAN. Subnet Mask The default value 255.255.255.0 is standard for small (class "C") networks. For other networks, use the Subnet Mask for the LAN segment to which the Wireless ADSL Router is attached (the same value as the PCs on that LAN segment). DHCP Server • If Enabled, the Wireless ADSL Router will allocate IP Addresses to PCs (DHCP clients) on your LAN when they start up. The default (and recommended) value is Enabled. • If you are already using a DHCP Server, this setting must be Disabled, and the existing DHCP server must be re-configured to treat the Wireless ADSL Router as the default Gateway. See the following section for further details. • The Start IP Address and Finish IP Address fields set the values used by the DHCP server when allocating IP Addresses to DHCP clients. This range also determines the number of DHCP clients supported. See the following section for further details on using DHCP. DHCP What DHCP Does A DHCP (Dynamic Host Configuration Protocol) Server allocates a valid IP address to a DHCP Client (PC or device) upon request. • The client request is made when the client device starts up (boots).
Wireless ADSL Router User Guide 14 • The DHCP Server provides the Gateway and DNS addresses to the client, as well as allocating an IP Address. • The Wireless ADSL Router can act as a DHCP server. • Windows 95/98/ME and other non-Server versions of Windows will act as a DHCP client. This is the default Windows setting for the TCP/IP network protocol. However, Windows uses the term Obtain an IP Address automatically instead of "DHCP Client". • You must NOT have two (2) or more DHCP Servers on the same LAN segment. (If your LAN does not have other Routers, this means there must only be one (1) DHCP Server on your LAN.) Using the Wireless ADSL Router's DHCP Server This is the default setting. The DHCP Server settings are on the LAN screen. On this screen, you can: • Enable or Disable the Wireless ADSL Router's DHCP Server function. • Set the range of IP Addresses allocated to PCs by the DHCP Server function. You can assign Fixed IP Addresses to some devices while using DHCP, provided that the Fixed IP Addresses are NOT within the range used by the DHCP Server. Using another DHCP Server You can only use one (1) DHCP Server per LAN segment. If you wish to use another DHCP Server, rather than the Wireless ADSL Router's, the following procedure is required. 1. Disable the DHCP Server feature in the Wireless ADSL Router. This setting is on the LAN screen. 2. Configure the DHCP Server to provide the Wireless ADSL Router's IP Address as the Default Gateway. To Configure your PCs to use DHCP This is the default setting for TCP/IP for all non-Server versions of Windows. See Chapter 4 - Client Configuration for the procedure to check these settings.

37 Chapter 6 Advanced Features This Chapter explains when and how to use the Wireless ADSL Router's "Advanced" Features. Overview The following advanced features are provided: • Dynamic DNS • Firewall Rules and Services • Scheduling • URL filter • Virtual Servers Dynamic DNS (Domain Name Server) This free service is very useful when combined with the Virtual Server feature. It allows Internet users to connect to your Virtual Servers using a URL, rather than an IP Address. This also solves the problem of having a dynamic IP address. With a dynamic IP address, your IP address may change whenever you connect, which makes it difficult to connect to you. The DynDNS Service works as follows: 1. You must register for the service at http://www.dyndns.org (Registration is free). Your password will be E-mailed to you. 2. After registration, use the "Create New Host" option (at www.dyndns.org) to request your desired Domain name. 3. Enter your data from www.dyndns.org in the Wireless ADSL Router's DDNS screen. 4. The Wireless ADSL Router will then automatically ensure that your current IP Address is recorded at http://www.dyndns.org 5. From the Internet, users will be able to connect to your Virtual Servers (or DMZ PC) using your Domain name, as shown on this screen. 6
Advanced Features 38 Dynamic DNS Screen Select Advanced on the main menu, then Dynamic DNS, to see a screen like the following: Figure 27: DDNS Screen Data - Dynamic DNS Screen DDNS Service Use a Dynamic DNS Service Use this to enable or disable the DDNS feature as required.

For this PC, any restrictions set by the blocking above will be ignored. Trusted IP Address Type the IP address of the computer in the fields provided. Virtual Servers This feature, sometimes called Port Forwarding, allows you to make Servers on your LAN accessible to Internet users. Normally, Internet users would not be able to access a server on your LAN because: • Your Server does not have a valid external IP Address. • Attempts to connect to devices on your LAN are blocked by the firewall in this device. The "Virtual Server" feature solves these problems and allows Internet users to connect to your servers, as illustrated below. WirelessRouterWeb Server FTP ServerInternetRemote PC Remote PCUsing Web Server Using FTP Server(http://203.70.212.52) (ftp://203.70.212.52)203.70.212.52192.168.0.1(192.168.0.10) (192.168.0.20)(LAN IP Address)(Internet IP Address) Figure 35: Virtual Servers IP Address seen by Internet Users Note that, in this illustration, both Internet users are connecting to the same IP Address, but using different protocols. To Internet users, all virtual Servers on your LAN have the same IP Address. This IP Address is allocated by your ISP.
Wireless ADSL Router User Guide 49This address should be static, rather than dynamic, to make it easier for Internet users to connect to your Servers. However, you can use the DDNS (Dynamic DNS) feature to allow users to connect to your Virtual Servers using a URL, instead of an IP Address. Virtual Servers Screen • The "Virtual Servers" feature allows Internet Users to access PCs on your LAN. • The PCs must be running the appropriate Server Software. • For Internet Users, ALL of your Servers have the same IP address. This IP address is allocated by your ISP. • To make it easier for Internet users to connect to your Servers, you can use the "DDNS" feature. This allows Internet users to connect to your Servers with a URL, rather than an IP address. This technology works even if your ISP allocates dynamic IP addresses (IP address is allocated upon connection, so it may change each time you connect). Figure 36: Virtual Servers Screen Data - Virtual Servers Screen Servers Servers This lists a number of pre-defined Servers, plus any Servers you have defined. Details of the selected Server are shown in the "Properties" area. Properties Enable Use this to Enable or Disable support for this Server, as required. PC (Server) Enter the IP address of the PC for this Server. The PC must be running the appropriate Server software. For each entry, the PC must be running the appropriate Server software. If the desired Server type is not listed, you can define your own Servers, using the Firewall Rules.
Advanced Features 50 Connecting to the Virtual Servers Once configured, anyone on the Internet can connect to your Virtual Servers. They must use the Internet IP Address (the IP Address allocated to you by your ISP). e.g. http://203.70.212.52 ftp://203.70.212.52 It is more convenient if you are using a Fixed IP Address from your ISP, rather than Dynamic. However, you can use the Dynamic DNS feature, described in the following section, to allow users to connect to your Virtual Servers using a URL, rather than an IP Address. From the Internet, ALL Virtual Servers have the IP Address allocated by your ISP
51 Chapter 7 Advanced Administration This Chapter explains the settings available via the "Administration" section of the menu.

Ensure your Internet connection is established, and start your Web Browser. 2. In the "Address" bar, enter "HTTP://" followed by the Internet IP Address of the Wireless ADSL Router. If the port number is not 80, the port number is also required. (After the IP Address, enter ":" followed by the port number.) e.g. HTTP://123.123.123.123:8080 This example assumes the WAN IP Address is 123.123.123.123, and the port number is 8080.
Advanced Administration 60Routing Overview • If you don't have other Routers or Gateways on your LAN, you can ignore the "Routing" page completely. • If the Wireless ADSL Router is only acting as a Gateway for the local LAN segment, ignore the "Routing" page even if your LAN has other Routers. • If your LAN has a standard Router (e.g. Cisco) on your LAN, and the Wireless ADSL Router is to act as a Gateway for all LAN segments, enable RIP (Routing Information Protocol) and ignore the Static Routing table. • If your LAN has other Gateways and Routers, and you wish to control which LAN segments use each Gateway, do NOT enable RIP (Routing Information Protocol). Configure the Static Routing table instead. (You also need to configure the other Routers.) • If using Windows 2000 Data center Server as a software Router, enable RIP on the Wireless ADSL Router, and ensure the following Windows 2000 settings are correct: • Open Routing and Remote Access • In the console tree, select Routing and Remote Access , [server name], IP Routing, RIP • In the "Details" pane, right-click the interface you want to configure for RIP version 2, and then click "Properties". • On the "General" tab, set Outgoing packet protocol to "RIP version 2 broadcast", and Incoming packet protocol to "RIP version 1 and 2". Routing Screen The routing table is accessed by the Routing link on the Administration menu. Using this Screen Generally, you will use either RIP (Routing Information Protocol) OR the Static Routing Table, as explained above, although is it possible to use both methods simultaneously. Static Routing Table • If RIP is not used, an entry in the routing table is required for each LAN segment on your Network, other than the segment to which this device is attached. • The other Routers must also be configured. See Configuring Other Routers on your LAN later in this chapter for further details and an example.

Edit Update the current Static Routing Table entry, using the data shown in the table area on screen. Delete Delete the current Static Routing Table entry. Save Save the RIP setting. This has no effect on the Static Routing Table. Configuring Other Routers on your LAN It is essential that all IP packets for devices not on the local LAN be passed to the Wireless ADSL Router, so that they can be forwarded to the external LAN, WAN, or Internet. To achieve this, the local LAN must be configured to use the Wireless ADSL Router as the Default Route or Default Gateway.
Advanced Administration 62 Local Router The local router is the Router installed on the same LAN segment as the Wireless ADSL Router. This router requires that the Default Route is the Wireless ADSL Router itself. Typically, routers have a special entry for the Default Route. It should be configured as follows. Destination IP Address Normally 0.0.0.0, but check your router documentation. Network Mask Normally 0.0.0.0, but check your router documentation. Gateway IP Address The IP Address of the Wireless ADSL Router. Metric 1 Other Routers on the Local LAN Other routers on the local LAN must use the Wireless ADSL Router's Local Router as the Default Route. The entries will be the same as the Wireless ADSL Router's local router, with the exception of the Gateway IP Address. • For a router with a direct connection to the Wireless ADSL Router's local Router, the Gateway IP Address is the address of the Wireless ADSL Router's local router. • For routers which must forward packets to another router before reaching the Wireless ADSL Router's local router, the Gateway IP Address is the address of the intermediate router.

65 Appendix A Troubleshooting This Appendix covers the most likely problems and their solutions. Overview This chapter covers some common problems that may be encountered while using the Wireless ADSL Router and some possible solutions to them. If you follow the suggested steps and the Wireless ADSL Router still does not function properly, contact your dealer for further advice. General Problems Problem 1: Can't connect to the Wireless ADSL Router to configure it. Solution 1: Check the following: • The Wireless ADSL Router is properly installed, LAN connections are OK, and it is powered ON. • Ensure that your PC and the Wireless ADSL Router are on the same network segment. (If you don't have a router, this must be the case.) • If your PC is set to "Obtain an IP Address automatically" (DHCP client), restart it. • If your PC uses a Fixed (Static) IP address, ensure that it is using an IP Address within the range 192.168.0.2 to 192.168.0.254 and thus compatible with the Wireless ADSL Router's default IP Address of 192.168.0.1. Also, the Network Mask should be set to 255.255.255.0 to match the Wireless ADSL Router. In Windows, you can check these settings by using Control Panel-Network to check the Properties for the TCP/IP protocol. Internet Access Problem 1: When I enter a URL or IP address I get a time out error. Solution 1: A number of things could be causing this. Try the following troubleshooting steps. • Check if other PCs work. If they do, ensure that your PCs IP settings are correct. If using a Fixed (Static) IP Address, check the Network Mask, Default gateway and DNS as well as the IP Address. • If the PCs are configured correctly, but still not working, check the Wireless ADSL Router. Ensure that it is connected and ON. Connect to it and check its settings. (If you can't connect to it, check the LAN and power connections.) • Check the Wireless ADSL Router's status screen to see if it is working correctly. A
Appendix A - Troubleshooting 66 Problem 2: Some applications do not run properly when using the Wireless ADSL Router. Solution 2: The Wireless ADSL Router processes the data passing through it, so it is not transparent. For incoming connections, you must use the Virtual Server or Firewall Rules to specify the PC which will receive the incoming traffic. You can also use the DMZ function. This should work with almost every application, but: • It is a security risk, since the firewall is disabled. • Only one (1) PC can use this feature. Wireless Access Problem 1: My PC can't locate the Wireless Access Point. Solution 1: Check the following. • Your PC is set to Infrastructure Mode. (Access Points are always in Infrastructure Mode) • The SSID on your PC and the Wireless Access Point are the same. Remember that the SSID is case-sensitive. So, for example "Workgroup" does NOT match "workgroup". • Both your PC and the Wireless ADSL Router must have the same setting for WEP. The default setting for the Wireless ADSL Router is disabled, so your wireless station should also have WEP disabled. • If WEP is enabled on the Wireless ADSL Router, your PC must have WEP enabled, and the key must match. • If the Wireless ADSL Router's Wireless screen is set to Allow Trusted PCs only, then each of your Wireless stations must have been designated as "Trusted", or the Wireless station will be blocked. • To see if radio interference is causing a problem, see if connection is possible when close to the Wireless ADSL Router. Remember that the connection range can be as little as 100 feet in poor environments. Problem 2: Wireless connection speed is very slow. Solution 2: The wireless system will connect at the highest possible speed, depending on the distance and the environment. To obtain the highest possible connection speed, you can experiment with the following: • Wireless ADSL Router location. Try adjusting the location and orientation of the Wireless ADSL Router. • Wireless Channel If interference is the problem, changing to another channel may show a marked improvement. • Radio Interference Other devices may be causing interference. You can experiment by switching other devices Off, and see if this helps. Any "noisy" devices should be shielded or relocated. • RF Shielding
Wireless ADSL Router User Guide 67 Your environment may tend to block transmission between the wireless stations. This will mean high access speed is only possible when close to the Wireless ADSL Router.
68 Appendix B About Wireless LANs This Appendix provides some background information about using Wireless LANs (WLANs). Modes Wireless LANs can work in either of two (2) modes: • Ad-hoc • Infrastructure Ad-hoc Mode Ad-hoc mode does not require an Access Point or a wired (Ethernet) LAN. Wireless Stations (e.g. notebook PCs with wireless cards) communicate directly with each other. Infrastructure Mode In Infrastructure Mode, one or more Access Points are used to connect Wireless Stations (e.g. Notebook PCs with wireless cards) to a wired (Ethernet) LAN. The Wireless Stations can then access all LAN resources. Access Points can only function in "Infrastructure" mode, and can communicate only with Wireless Stations which are set to "Infrastructure" mode. BSS/ESS BSS A group of Wireless Stations and a single Access Point, all using the same ID (SSID), form a Basic Service Set (BSS). Using the same SSID is essential. Devices with different SSIDs are unable to communicate with each other. ESS A group of Wireless Stations, and multiple Access Points, all using the same ID (ESSID), form an Extended Service Set (ESS). Different Access Points within an ESS can use different Channels. In fact, to reduce interference, it is recommended that adjacent Access Points SHOULD use different channels. As Wireless Stations are physically moved through the area covered by an ESS, they will automatically change to the Access Point which has the least interference or best performance. This capability is called Roaming. (Access Points do not have or require Roaming capabilities.) B
Wireless ADSL Router User Guide 69Channels The Wireless Channel sets the radio frequency used for communication. • Access Points use a fixed Channel. You can select the Channel used. This allows you to choose a Channel which provides the least interference and best performance. In the USA and Canada, 11 channel are available. If using multiple Access Points, it is better if adjacent Access Points use different Channels to reduce interference. • In "Infrastructure" mode, Wireless Stations normally scan all Channels, looking for an Access Point. If more than one Access Point can be used, the one with the strongest signal is used. (This can only happen within an ESS.) • If using "Ad-hoc" mode (no Access Point), all Wireless stations should be set to use the same Channel. However, most Wireless stations will still scan all Channels to see if there is an existing "Ad-hoc" group they can join. WEP WEP (Wired Equivalent Privacy) is a standard for encrypting data before it is transmitted. This is desirable because it is impossible to prevent snoopers from receiving any data which is transmitted by your Wireless Stations. But if the data is encrypted, then it is meaningless unless the receiver can decrypt it. If WEP is used, the Wireless Stations and the Access Point must have the same settings for each of the following: WEP Off, 64 Bit, 128 Bit Key For 64 Bit encryption, the Key value must match. For 128 Bit encryption, the Key value must match WEP Authentication Open System or Shared Key. Wireless LAN Configuration To allow Wireless Stations to use the Access Point, the Wireless Stations and the Access Point must use the same settings, as follows: Mode On client Wireless Stations, the mode must be set to "Infrastructure". (The Access Point is always in "Infrastructure" mode.) SSID (ESSID) Wireless Stations should use the same SSID (ESSID) as the Access Point they wish to connect to. Alternatively, the SSID can be set to "any" or null (blank) to allow connection to any Access Point. WEP The Wireless Stations and the Access Point must use the same settings for WEP (Off, 64 Bit, 128 Bit). WEP Key: If WEP is enabled, the Key must be the same on the Wireless Stations and the Access Point. WEP Authentication: If WEP is enabled, all Wireless Stations must use the same setting as the Access Point (either "Open System" or "Shared Key").
