1. Introduction This Chapter provides an overview of the Wireless Router's features and ca-pabilities. Congratulations on the purchase of your new Wireless Router. The Wireless Router is a multi-function device providing the following services: • Shared Broadband Internet Access for all LAN users. • 4-Port Switching Hub for 10BaseT or 100BaseT connections. • Wireless Access Point for 802.11b Wireless Stations. Figure 1: Wireless Router 1.1 Wireless Router Features The Wireless 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 Router, using only a single external IP Address. The local (invalid) IP Addresses are hidden from external sources. This process is called NAT (Network Ad-dress Translation). • DSL & Cable Modem Support. The Wireless Router has a 10BaseT Ethernet port for connecting a DSL or Cable Modem. All popular DSL and Cable Modems are supported. SingTel RAS and Big Pond (Australia) login support is also included. • PPPoE, PPTP, SingTel RAS and Telstra Big Pond Support. The Internet (WAN port) connection supports PPPoE (PPP over Ethernet), PPTP (Peer-to-Peer Tunneling Pro-tocol), SingTel RAS and Telstra Big Pond (Australia), as well as "Direct Connection" type services. • Fixed or Dynamic IP Address. On the Internet (WAN port) connection, the Wireless Router supports both Dynamic IP Address (IP Address is allocated on connection) and Fixed IP Address. 3
4Advanced Internet Functions • Communication Applications. Support for Internet communication applications, such as interactive Games, Telephony, and Conferencing applications, which are often difficult to use when behind a Firewall, is included. • Special Internet Applications. 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. • DMZ. One (1) PC on your local LAN can be configured to allow unrestricted 2-way communication with Servers or individual users on the Internet. This provides the ability to run programs which are incompatible with Firewalls. • URL Filter. Use the URL Filter to block access to undesirable Web sites by LAN users. • Internet Access Log. See which Internet connections have been made. • 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 Router complies with the IEEE802.11b (DSSS) specifications for Wireless LANs. • Speeds to 22Mbps. All speeds up to the 802.11b maximum of 11Mbps are supported, as well as the TI "B+" enhancement which allows 22Mbps between compatible devices. • WEP support. Support for WEP (Wired Equivalent Privacy) is included. Key sizes of 64 Bit, 128 Bit and 256 Bit (for TI devices only) are supported. • Access Control. The Access Control feature can 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 Router incorporates a 4-port 10/100BaseT switch-ing 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 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 Router's RIP (Routing Information Protocol) support and built-in static routing table. Configuration & Management • Easy Setup. Use your WEB browser from anywhere on the LAN or WLAN for configu-ration. • Remote Management. The Wireless 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. • UPnP Support. UPnP (Universal Plug and Play) allows automatic discovery and con-figuration of the Wireless Router. UPnP is by supported by Windows ME, XP, or later.
5Security 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) tech-nology 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 Router. • Stateful Inspection Firewall. All incoming data packets are monitored and all incom-ing 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 band-width and so many resources that Internet access becomes unavailable. The Wireless Router incorporates protection against DoS attacks. 1.2 Package Contents The following items should be included: • The Wireless 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 113.2 Configuration Program The Wireless Router contains an HTTP server. This enables you to connect to it, and configure it, using your Web Browser. Your Browser must support JavaScript. The configuration program has been tested on the following browsers: • Netscape V4.08 or later • Internet Explorer V4 or later Preparation Before attempting to configure the Wireless Router, please ensure that: • Your PC can establish a physical connection to the Wireless Router. The PC and the Wireless Router must be directly connected (using the Hub ports on the Wireless Router) or on the same LAN segment. • The Wireless Router must be installed and powered ON. • If the Wireless Router's default IP Address (192.168.2.1) is already used by another device, the other device must be turned OFF until the Wireless Router is allocated a new IP Address during configuration. Using UPnP If your Windows system supports UPnP, an icon for the Wireless Router will appear in the system tray, notifying you that a new network device has been found, and offering to create a new desktop shortcut to the newly-discovered device. • Unless you intend to change the IP Address of the Wireless Router, you can accept the desktop shortcut. • Whether you accept the desktop shortcut or not, you can always find UPnP devices in My Network Places (previously called Network Neighborhood). • Double - click the icon for the Wireless Router (either on the Desktop, or in My Network Places) to start the configuration. Refer to the following section 3.3 Setup Wizard for de-tails of the initial configuration process. Using your Web Browser To establish a connection from your PC to the Wireless Router: 1. After installing the Wireless Router in your LAN, start your PC. If your PC is already running, restart it. 2. Start your WEB browser. 3. In the Address box, enter "HTTP://" and the IP Address of the Wireless Router, as in this example, which uses the Wireless Router's default IP Address: HTTP://192.168.2.1
12If you can't connect If the Wireless Router does not respond, check the following: • The Wireless Router is properly installed, LAN connection is OK, and it is powered ON. You can test the connection by using the "Ping" command: • Open the MS-DOS window or command prompt window. • Enter the command: ping 192.168.2.1 If no response is received, either the connection is not working, or your PC's IP address is not compatible with the Wireless Router's IP Address. (See next item.) • If your PC is using a fixed IP Address, its IP Address must be within the range 192.168.2.2 to 192.168.2.254 to be compatible with the Wireless Router's de-fault IP Address of 192.168.2.1. Also, the Network Mask must be set to 255.255.255.0. See Chapter 4 - PC Configuration for details on checking your PC's TCP/IP settings. • Ensure that your PC and the Wireless Router are on the same network seg-ment. (If you don't have a router, this must be the case.)
Setup 133.3 Setup Wizard The first time you connect to the Wireless Router, the Setup Wizard will run automatically. (The Setup Wizard will also run if the Wireless Router's default settings are restored.) 1. Step through the Wizard until finished. • You need to know the type of Internet connection service used by your ISP. Check the data supplied by your ISP. • The common connection types are explained in the tables below. 2. On the final screen of the Wizard, run the test and check that an Internet connection can be established. 3. If the connection test fails: • Check your data, the Cable/DSL modem, and all connections. • Check that you have entered all data correctly. • If using a Cable modem, your ISP may have recorded the MAC (physical) address of your PC. Run the Wizard, and on the Cable Modem screen, use the "Clone MAC ad-dress" button to copy the MAC address from your PC to the Wireless Router. Common Connection Types Cable Modems Type Details ISP Data required Dynamic IP Address Your IP Address is allocated automatically, when you connect to your ISP. Usually, none. However, some ISP's may require you to use a particular Hostname, Domain name, or MAC (physical) address. Static (Fixed) IP Address Your ISP allocates a perma-nent IP Address to you.

Setup 15Home Screen After finishing the Setup Wizard, you will see the Home screen. When you connect in future, you will see this screen when you connect. An example screen is shown below. Figure 5: Home Screen Navigation & Data Input • Use the menu bar on the top of the screen, and the "Back" button on your Browser, for navigation. • Changing to another screen without clicking "Save" does NOT save any changes you may have made. You must "Save" before changing screens or your data will be ignored. On each screen, clicking the "Help" button will display help for that screen. From any help screen, you can access the list of all help files (help index).
163.4 LAN Screen Use the LAN link on the main menu to reach the LAN screen. The example screen is shown below. 2 Figure 6: LAN Screen Data - LAN Screen TCP/IP IP Address IP address for the Wireless 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 Router is attached (the same value as the PCs on that LAN segment). DHCP Server • If Enabled, the Wireless 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 Router as the default Gateway. See the follow-ing 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. Buttons Save Save the data on screen. Cancel The "Cancel" button will discard any data you have entered and reload the file from the Wireless Router.
Setup 17DHCP 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). • The DHCP Server provides the Gateway and DNS addresses to the client, as well as allocating an IP Address. • The Wireless 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 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 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 Router's, the following procedure is required. 1. Disable the DHCP Server feature in the Wireless Router. This setting is on the LAN screen. 2. Configure the DHCP Server to provide the Wireless Router's IP Address as the Default Gateway. To Configure your PCs to use DHCP This is the default setting for TCP/IP under Windows 95/98/ME. See Chapter 4 - Client Configuration for the procedure to check these settings.
183.5 Wireless Screen The Wireless Access Point settings must match the other Wireless stations. To change the Wireless Router's default settings for the Wireless Access Point feature, use the Wireless link on the main menu to reach the Wireless screen. An example screen is shown below. Figure 7: Wireless Screen Data - Wireless Screen Identification Regulatory Domain It is illegal to use this device in any location outside of the regulatory domain. Station name This is the same as the "Device Name" for the Wireless Router. On your PC, some Wireless status screens may display this name as the name of the Access Point in use. SSID (ESSID) • If using an ESS (Extended Service Set, with multiple access points) this ID is called an ESSID (Extended Service Set Identi-fier). • To communicate, all Wireless stations should use the same SSID/ESSID. Options Channel No. • Select the Channel you wish to use on your Wireless LAN. • If you experience interference (shown by lost connections and/or slow data transfers) you may need to experiment with different channels to see which is the best. • If using multiple Access Points, adjacent Access Points should use different Channels to reduce interference.
Setup 19WEP data encryption • WEP (Wired Equivalent Privacy) status will display "Enabled" or "Disabled", depending on whether WEP is being used.

4.PC Configuration This Chapter details the PC Configuration required on the local ("Internal") LAN. 4.1 Overview For each PC, the following may need to be configured: • TCP/IP network settings • Internet Access configuration • Wireless configuration 4.2 Windows Clients This section describes how to configure Windows clients for Internet access via the Wireless Router. The first step is to check the PC's TCP/IP settings. The Wireless Router uses the TCP/IP network protocol for all functions, so it is essential that the TCP/IP protocol be installed and configured on each PC. TCP/IP Settings - Overview If using the default Wireless Router settings and the default Windows TCP/IP settings, no changes need to be made. • By default, the Wireless Router will act as a DHCP Server, automatically providing a suitable IP Address (and related information) to each PC when the PC boots. • For all non-Server versions of Windows, the default TCP/IP setting is to act as a DHCP client. If using a Fixed (specified) IP address, the following changes are re-quired: • The Gateway must be set to the IP address of the Wireless Router • The DNS should be set to the address provided by your ISP. 23 If your LAN has a Router, the LAN Administrator must re-configure the Router itself. Refer to Chapter 8 - Ad-vanced Setup for details.

Figure 30: Internet Screen Communication Applications Most applications are supported transparently by the Wireless Router. But sometimes it is not clear which PC should receive an incoming connection. This problem could arise with the Communication Applications listed on this screen. If this problem arises, you can use this screen to set which PC should receive an incoming connection, as described below. Communication Applications Select an Application This lists applications which may generate incoming connections, where the destination PC (on your local LAN) is unknown.
Advanced Features Send incoming calls to This lists the PCs on your LAN. • If necessary, you can add PCs manually, using the "PC Database" option on the advanced menu. • For each application listed above, you can choose a destina-tion PC. • There is no need to "Save" after each change; you can set the destination PC for each application, then click "Save". Special Applications If you use Internet applications which use non-standard connections or port numbers, you may find that they do not function correctly because they are blocked by the Wireless Router's firewall. In this case, you can define the application as a "Special Application". Special Applications Screen This screen can be reached by clicking the Special Applications button on the Internet screen. You can then define your Special Applications. You will need detailed information about the application; this is normally available from the supplier of the application. Also, note that the terms "Incoming" and "Outgoing" on this screen refer to traffic from the client (PC) viewpoint Figure 31: Special Applications Screen 51
Wireless Router User Guide Data - Special Applications Screen Checkbox Use this to Enable or Disable this Special Application as required. Name Enter a descriptive name to identify this Special Application. Incoming Ports • Type - Select the protocol (TCP or UDP) used when you receive data from the special application or service. (Note: Some applications use different protocols for outgoing and incoming data). • Start - Enter the beginning of the range of port numbers used by the application server, for data you receive. If the application uses a single port number, enter it in both the "Start" and "Finish" fields. • Finish - Enter the end of the range of port numbers used by the applica-tion server, for data you receive. Outgoing Ports • Type - Select the protocol (TCP or UDP) used when you send data to the remote system or service. • Start - Enter the beginning of the range of port numbers used by the application server, for data you send to it. If the application uses a sin-gle port number, enter it in both the "Start" and "Finish" fields. • Finish - Enter the end of the range of port numbers used by the applica-tion server, for data you send to it. If the application uses a single port number, enter it in both the "Start" and "Finish" fields. Using a Special Application • Configure the Special Applications screen as required. • On your PC, use the application normally. Remember that only one (1) PC can use each Special application at any time. Also, when 1 PC is finished using a particular Special Ap-plication, there may need to be a "Time-out" before another PC can use the same Special Application. The "Time-out" period may be up to 3 minutes. 52 If an application still cannot function correctly, try using the "DMZ" feature. DMZ This feature, if enabled, allows one (1) computer on your LAN to be exposed to all users on the Internet, allowing unrestricted 2-way communication between the "DMZ PC" and other Internet users or Servers. • This allows almost any application to be used on the "DMZ PC". • The "DMZ PC" will receive all "Unknown" connections and data. • If the DMZ feature is enabled, you must select the PC to be used as the "DMZ PC". • The DMZ feature can be Enabled and Disabled on the Advanced Internet screen. The "DMZ PC" is effectively outside the Firewall, mak-ing it more vulnerable to attacks. For this reason, you should only enable the DMZ feature when required.
Advanced Features 53URL Filter The URL Filter allows you to block access to undesirable Web site • To use this feature, you must define "filter strings". If the "filter string" appears in a requested URL, the request is blocked. • Enabling the URL Filter also affects the Internet Access Log. If Enabled, the "Destination" field in the log will display the URL. Otherwise, it will display the IP Address. • The URL Filter can be Enabled or Disabled on the Advanced Internet screen. URL Filter Screen Click the "Configure URL Filter" button on the Internet screen to access the URL Filter screen. An example screen is shown below.

Advanced Features 616.5 Remote Management This feature allows you to manage the Wireless Router via the Internet. Figure 37: Remote Management Screen Data - Remote Management Screen Remote Management Enable Remote Management Enable to allow management via the Internet. If Disabled, this device will ignore management connection attempts from the Internet. Port Number Enter a port number between 1024 and 65535 (8080 is recom-mended). This port number must be specified when you connect (see below). Note: The default port number for HTTP (Web) connections is port 80, but using port 80 here will prevent the use of a Web "Virtual Server" on your LAN. (See Advanced Internet - Virtual Servers) Current IP Ad-dress You must use this IP Address to connect (see below). This IP Address is allocated by your ISP. But if using a Dynamic IP Address, this value can change each time you connect to your ISP. So it is better if your ISP allocates you a Fixed IP Address. To connect from a remote PC via the Internet 1. 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 Router. If the port number is not 80, the port number is also required. (After the IP Ad-dress, 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.
Wireless Router User Guide 626.6 Virtual Servers This feature 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 38: 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. This 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.
Advanced Features 63Virtual Servers Screen The Virtual Servers screen is reached by the Virtual Servers link on the Advanced screen. An example screen is shown below. Figure 39: Virtual Servers Screen This screen lists a number of pre-defined Servers, and allows you to define your own Servers. Details of the selected Server are shown in the "Properties" area. 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. • If Enabled, any incoming connections will be forwarded to the selected PC. • If Disabled, any incoming connection attempts will be blocked. PC (Server) Select the PC for this Server. The PC must be running the appro-priate Server software. Protocol Select the protocol (TCP or UDP) used by the Server.
Wireless Router User Guide Internal Port No. Enter the port number which the Server software is configured to use. External Port No. The port number used by Internet users when connecting to the Server. This is normally the same as the Internal Port Number. If it is different, this device will perform a "mapping" or "translation" function, allowing the server to use one port address, while clients use a different port address. Buttons Defaults This will delete any Servers you have defined, and set the pre-defined Servers to use their default port numbers. Disable All This will cause the "Enable" setting of all Virtual Servers to be set OFF. Update Selected Server Update the current Virtual Server entry, using the data shown in the "Properties" area on screen. Add as new Server Add a new entry to the Virtual Server list, using the data shown in the "Properties" area on screen. The entry selected in the list is ignored, and has no effect. Delete Delete the current Virtual Server entry. Note that the pre-defined Servers can not be deleted. Only Servers you have defined yourself can be deleted. Clear Form Clear all data from the "Properties" area, ready for input of a new Virtual Server entry. For each entry, the PC must be running the appropriate Server software. Defining your own Virtual Servers If the type of Server you wish to use is not listed on the Virtual Servers screen, you can define and manage your own Servers: Create a new Server: 1. Click "Clear Form" 2. Enter the required data, as described above. 3. Click "Add". 4. The new Server will now appear in the list. Modify (Edit) a Server: 1. Select the desired Server from the list 2. Make any desired changes (for example, change the Enable/Disable setting). 3. Click "Update" to save changes to the selected Server. Delete a Server: 1. Select the entry from the list. 2. Click "Delete". Note: You can only delete Servers you have defined. Pre-defined Server cannot be deleted. 64
Advanced Features 65 From the Internet, ALL Virtual Servers have the IP Address allocated by your ISP. 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. 6.7 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 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 Router's DDNS screen. 4. The Wireless Router will then automatically ensure that your current IP Address is re-corded 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.
Wireless Router User Guide 66Dynamic DNS Screen Select Advanced on the main menu, then Dynamic DNS, to see a screen like the following: Figure 40: DDNS Screen Data - Dynamic DNS Screen DDNS Service DDNS Service • You must sign up first to create a new account before using the service. The service is free. • Click this link to connect to the www.dyndns.org Web site. • Your initial password will be E-mailed to you; you can change this later if you wish. • After registration, use the "Create New Host" link (on the www.dyndns.org Web site) to request a domain name. DDNS Data User Name Enter the "User name" specified at the www.dyndns.org Web site when you registered.

Using any other characters may cause problems.. DDNS Status This message is returned by the DDNS Server at www.dyndns.org • Normally, this message should be "Update successful" (current IP address was updated on the www.dyndns.org server). • If the message is "No host", this indicates the host name entered
Advanced Features was not allocated to you. You need to connect to www.dyndns.org and correct this problem. 6.8 Upgrade Firmware The firmware (software) in the Wireless Router can be upgraded using your Web Browser. You must first download the upgrade file, and then select Upgrade on the Advanced menu. You will see a screen like the following. Figure 41: Upgrade Firmware Screen To perform the Firmware Upgrade: 1. Click the "Browse" button and navigate to the location of the upgrade file. 2. Select the upgrade file. Its name will appear in the Upgrade File field. 3. Click the "Start Upgrade" button to commence the firmware upgrade. 67 The Wireless Router is unavailable during the up-grade process, and must restart when the upgrade is completed. Any connections to or through the Wire-less Router will be lost.
687. Advanced Configuration This Chapter explains the settings available via the Advanced configuration section of the "Advanced" menu. 7.1 Overview Normally, it is not necessary to use these screens, or change any settings. These screens and settings are provided to deal with non-standard situations, or to provide additional options for advanced users. The settings available are: PC Database This is the list of PCs shown when you select the "DMZ PC" or a "Vir-tual Server". This database is maintained automatically, but you can add and delete entries for PCs which use a Fixed (Static) IP Address. Options Various options, such as backup DNS, UPnP, and enable TFTP firm-ware upgrade option. Security Firewall and other security-related settings. Logs View or clear all logs, set E-Mailing of log files. MAC Address Set the MAC (hardware) address used on the Internet (WAN port) interface. This is required only if your ISP has recorded the MAC (hardware) address you should use. Routing Only required if your LAN has other Routers or Gateways.
Advanced Configuration 697.2 PC Database The PC Database is used whenever you need to select a PC (e.g. for the "DMZ" PC). It elimi-nates the need to enter IP addresses. Also, you do not need to use fixed IP addresses on your LAN. PC Database Screen An example PC Database screen is shown below. Figure 42: PC Database • PCs which are "DHCP Clients" are automatically added to the database, and updated as required. • By default, non-Server versions of Windows act as "DHCP Clients"; this setting is called "Obtain an IP Address automatically". • The Wireless Router uses the "Hardware Address" to identify each PC, not the name or IP address. The "Hardware Address" can only change if you change the PC's network card or adapter. • This system means you do NOT need to use Fixed (static) IP addresses on your LAN. However, you can add PCs using Fixed (static) IP Addresses to the PC database if re-quired.
Wireless Router User Guide 70Data - PC Database Screen Known PCs This lists all current entries. Data displayed is name (IP Address) type. The "type" indicates whether the PC is connected to the LAN. Name If adding a new PC to the list, enter its name here. It is best if this matches the PC's "hostname". IP Address Enter the IP Address of the PC. The PC will be sent a "ping" to deter-mine its hardware address. If the PC is not available (not connected, or not powered On) you will not be able to add it. Buttons Add This will add the new PC to the list. The PC will be sent a "ping" to determine its hardware address. If the PC is not available (not con-nected, or not powered On) you will not be able to add it. Delete Delete the selected PC from the list. This should be done in 2 situa-tions: • The PC has been removed from your LAN. • The entry is incorrect. Refresh Update the data on screen. Generate Report Display a read-only list showing full details of all entries in the PC database. Advanced Administration View the Advanced version of the PC database screen. See below for details.
Advanced Configuration 71PC Database (Admin) This screen is displayed if the "Advanced Administration" button on the PC Database is clicked. It provides more control than the standard PC Database screen. Figure 43: PC Database (Admin) Data - PC Database ( Admin) Screen Known PCs This lists all current entries. Data displayed is name (IP Address) type. The "type" indicates whether the PC is connected to the LAN. PC Properties Name If adding a new PC to the list, enter its name here. It is best if this matches the PC's "hostname".
Wireless Router User Guide 72IP Address Select the appropriate option: • Automatic - The PC is set to be a DHCP client (Windows: "Ob-tain an IP address automatically"). The Wireless Router will allocate an IP address to this PC when requested to do so. The IP address could change, but normally won't. • DCHP Client - Reserved IP Address - Select this if the PC is set to be a DCHP client, and you wish to guarantee that the Wireless Router will always allocate the same IP Address to this PC. Enter the required IP address. Only the last field is required; the other fields must match the Wireless Router's IP address. • Fixed IP Address - Select this if the PC is using a Fixed (Static) IP address. Enter the IP address allocated to the PC. (The PC must be configured to use this IP address.) MAC Address Select the appropriate option • Automatic discovery - Select this to have the Wireless Router contact the PC and find its MAC address. This is only possible if the PC is connected to the LAN and powered On. • MAC is - Enter the MAC address on the PC. The MAC address is also called the "Hardware Address", "Physical Address", or "Net-work Adapter Address". The Wireless Router uses this to provide a unique identifier for each PC. Because of this, the MAC address can NOT be left blank. Buttons Add as New Entry Add a new PC to the list, using the data in the "Properties" box. If "Automatic discovery" (for MAC address) is selected, the PC will be sent a "ping" to determine its hardware address. This will fail unless the PC is connected to the LAN, and powered on. Update Selected PC Update (modify) the selected PC, using the data in the "Properties" box. Clear Form Clear the "Properties" box, ready for entering data for a new PC. Refresh Update the data on screen. Generate Report Display a read-only list showing full details of all entries in the PC database. Standard Screen Click this to view the standard "PC Database" screen.
Advanced Configuration 737.3 Options This screen allows advanced users to enter or change a number of settings. For normal opera-tion, there is no need to use this screen or change any settings. An example Options screen is shown below. Figure 44: Options Screen Data - Options Screen Backup DNS IP Address Enter the IP Address of the DNS (Domain Name Servers) here. These DNS will be used only if the primary DNS is unavailable. TFTP Enable Firm-ware Upgrade using TFTP • If enabled, TFTP (Trivial FTP) can be used to upgrade the firm-ware in this device. This is normally not required; a Windows utility is available for this purpose. • You must obtain the firmware upgrade file first; instructions for using TFTP will be available with the upgrade. UPnP Enable UPnP Services • UPnP (Universal Plug and Play) allows automatic discovery and configuration of equipment attached to your LAN. UPnP is by supported by Windows ME, XP, or later. • If Enabled, this device will be visible via UPnP. • If Disabled, this device will not be visible via UPnP.
Wireless Router User Guide 74Allow Configu-ration... • If checked, then UPnP users can change the configuration. • If Disabled, UPnP users can only view the configuration. But currently, this restriction only applies to users running Windows XP, who access the Properties via UPnP. (e.g. Right - click the Wireless Router in My Network Places, and select Properties) Allow Internet access to be disabled • If checked, then UPnP users can disable Internet access via this device. • If Disabled, UPnP users can NOT disable Internet access via this device. But currently, this restriction only applies to users running Windows XP, who access the Properties via UPnP. (e.g. Right - click the Wireless Router in My Network Places, and select Prop-erties) MTU MTU size MTU (Maximum Transmission Unit) value should only be changed if advised to do so by Technical Support. • Enter a value between 1 and 1500. • This device will still auto-negotiate with the remote server, to set the MTU size. The smaller of the 2 values (auto-negotiated, or en-tered here) will be used. • For direct connections (not PPPoE or PPTP), the MTU used is always 1500.
Advanced Configuration 757.4 Security This screen allows you to set Firewall and other security-related options. Figure 45: Security Screen Data - Security Screen Firewall Enable DoS Firewall If enabled, DoS (Denial of Service) attacks will be detected and blocked. The default is enabled. It is strongly recommended that this setting be left enabled. Note: • A DoS attack does not attempt to steal data or damage your PCs, but overloads your Internet connection so you can not use it - the service is unavailable. • This device uses "Stateful Inspection" technology. This system can detect situations where individual TCP/IP packets are valid, but collectively they become a DoS attack. Threshold This setting affects the number of "half-open" connections allowed. • A "half-open" connection arises when a remote client contacts the Server with a connection request, but then does not reply to the Server's response. • While the optimum number of "half-open" connections allowed (the "Threshold") depends on many factors, the most important factor is the available bandwidth of your Internet connection. • Select the setting to match the bandwidth of your Internet connec-tion.
Wireless Router User Guide 76Options Respond to ICMP The ICMP protocol is used by the "ping" and "traceroute" programs, and by network monitoring and diagnostic programs. • If checked, the Wireless Router will repond to ICMP packets received from the Internet. • If not checked, ICMP packets from the Internet will be ignored. Disabling this option provides a slight increase in security. Allow IPsec The IPSec protocol is used to establish a secure connection, and is widely used by VPN (Virtual Private Networking) programs. • If checked, IPSec connections are allowed. • If not checked, IPSec connections are blocked. Allow PPTP PPTP (Point to Point Tunneling Protocol) is widely used by VPN (Virtual Private Networking) programs. • If checked, PPTP connections are allowed. • If not checked, PPTP connections are blocked. Allow L2TP L2TP is a protocol developed by Cisco for VPNs (Virtual Private Networks). • If checked, L2TP connections are allowed. • If not checked, L2TP connections are blocked.
Advanced Configuration 777.5 Logs The Logs record various types of activity on the Wireless Router. This data is useful for troubleshooting, but enabling all logs will generate a large amount of data and adversely affect performance. Since only a limited amount of log data can be stored in the Wireless Router, log data can also be E-mailed to your PC. Figure 46: Logs Screen Data - Logs Screen Enable Logs Outgoing Connec-tions If selected, Outgoing Internet connections are logged. Normally, the (Internet) "Destination" will be shown as an IP address. But if the "URL Filter" is enabled, the "Destination" will be shown as a URL. Access Control If enabled, the log will include attempted outgoing connections which have been blocked by the "Access Control" feature. DoS Attacks If enabled, this log will show details of DoS (Denial of Service) attacks which have been blocked by the built-in Firewall.
Wireless Router User Guide 78Timezone Select the correct Timezone for your location. This is required for the date/time shown on the logs to be correct. E-Mail Reports Send E-mail alert If enabled, an E-mail will be sent immediately if a DoS (Denial of Service) attack is detected. If enabled, the E-mail address infor-mation must be provided. E-mail Logs You can choose to have the logs E-mailed to you, by enabling either or both checkboxes. If enabled, the Log will sent to the specified E-mail address. The interval between E-mails is deter-mined by the "Send" setting. Send Select the desired option for sending the log by E-mail. • When log is full - The time is not fixed. The log will be sent when the log is full, which will depend on the volume of traf-fic. • Every day, Every Monday ... - The log is sent on the interval specified. • If "Every day" is selected, the log is sent at the time specified. • If the day is specified, the log is sent once per week, on the specified day. • Select the time of day you wish the E-mail to be sent. • If the log is full before the time specified to send it, it will be sent regardless. E-Mail Address E-mail Address Enter the E-mail address the Log is to be sent to. The E-mail will also show this address as the Sender's address. Subject Enter the text string to be shown in the "Subject" field for the E-mail. SMTP Server Enter the address or IP address of the SMTP (Simple Mail Trans-port Protocol) Server you use for outgoing E-mail. Port No. Enter the port number used to connect to the SMTP Server. The default value is 25.
Advanced Configuration 797.6 MAC Address The MAC (hardware) address is a low-level network identifier. It may be called "MAC Ad-dress", "Hardware Address", or "Physical Address". On a PC, this address is associated with the Network card or adapter. The address on the MAC Address screen is the address on the Internet (WAN port) interface, and has no effect on the LAN interface. • If your ISP asks for the "Network Adapter Address", "Physical Address", "Hardware Address", or "MAC Address" for the PC the DSL/Cable modem is connected to, provide this value. • If your ISP has already recorded a MAC address, you can change the address used by the Wireless Router to match the address recorded by your ISP. MAC Address Screen Select MAC Address from the Advanced menu to reach a screen like the example below. Figure 47: MAC address Screen Data - MAC address Screen MAC (hardware) Address The current MAC (hardware) address is displayed. If your ISP has recorded a Hardware Address, you can "spoof" that address by entering it in the address field. The hardware address consists of 12 characters, where each character is a digit (0..9) or a character between A and F. Buttons Default Inserts the default MAC address into the MAC address field. You must click "Save" to actually change the address used. Copy from PC Inserts the MAC address from your PC into the MAC address field. You must click "Save" to actually change the address used. Save Save your changes to the Wireless Router. Cancel Reverse any changes made since the last "Save".
Wireless Router User Guide 80 If the MAC address is changed, the Wireless Router must restart. 7.7 Routing Overview • If you don't have other Routers or Gateways on your LAN, you can ignore the "Routing" page completely. • If the Wireless 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 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 seg-ments 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 Wire-less 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 broadcasts", and Incoming packet protocol to "RIP version 1 and 2". Routing Screen The routing table is accessed by the Routing link on the Advanced screen. 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.
Advanced Configuration Figure 48: Routing Screen Data - Routing Screen RIP Enable RIP Check this to enable the RIP (Routing Information Protocol) feature of the Wireless Router. The Wireless Router supports RIP 1 only. Static Routing Static Routing Table Entries This list shows all entries in the Routing Table. • The "Properties" area shows details of the selected item in the list. • Change any the properties as required, then click the "Update" button to save the changes to the selected entry. 81
Wireless Router User Guide 82Properties • Destination Network - The network address of the remote LAN segment. For standard class "C" LANs, the network address is the first 3 fields of the Destination IP Address. The 4th (last) field can be left at 0. • Network Mask - The Network Mask for the remote LAN segment. For class "C" networks, the default mask is 255.255.255.0 • Gateway IP Address - The IP Address of the Gateway or Router which the Wireless Router must use to communicate with the destination above. (NOT the router attached to the remote segment.) • Metric - The number of "hops" (routers) to pass through to reach the remote LAN segment. The shortest path will be used. The default value is 1. Buttons Save Save the RIP setting. This has no effect on the Static Routing Table. Add Add a new entry to the Static Routing table, using the data shown in the "Properties" area on screen. The entry selected in the list is ignored, and has no effect. Update Update the current Static Routing Table entry, using the data shown in the "Properties" area on screen. Delete Delete the current Static Routing Table entry. Clear Form Clear all data from the "Properties" area, ready for input of a new entry for the Static Routing table. Generate Report Generate a read-only list of all entries in 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 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 Router as the Default Route or Default Gateway. Local Router The local router is the Router installed on the same LAN segment as the Wireless Router. This router requires that the Default Route is the Wireless 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 Router. Metric 1
Advanced Configuration Other Routers on the Local LAN Other routers on the local LAN must use the Wireless Router's Local Router as the Default Route. The entries will be the same as the Wireless Router's local router, with the exception of the Gateway IP Address. • For a router with a direct connection to the Wireless Router's local Router, the Gateway IP Address is the address of the Wireless Router's local router. • For routers which must forward packets to another router before reaching the Wireless Router's local router, the Gateway IP Address is the address of the intermediate router.

85Appendix A Troubleshooting This Appendix covers the most likely problems and their solutions. A1. Overview This chapter covers some common problems that may be encountered while using the Wireless Router and some possible solutions to them. If you follow the suggested steps and the Wireless Router still does not function properly, contact your dealer for further advice. A2. General Problems Problem 1: Can't connect to the Wireless Router to configure it. Solution 1: Check the following: • The Wireless Router is properly installed, LAN connections are OK, and it is powered ON. • Ensure that your PC and the Wireless 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 192.168.2.2 to 192.168.2.254 and thus com-patible with the Wireless Router's default IP Address of 192.168.2.1. Also, the Network Mask should be set to 255.255.255.0 to match the Wireless Router. In Windows, you can check these settings by using Control Panel-Network to check the Properties for the TCP/IP protocol. A3. 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 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.) • If the Wireless Router is configured correctly, check your Internet connection (DSL/Cable modem etc) to see that it is working correctly. Problem 2: Some applications do not run properly when using the Wireless Router. Solution 2: The Wireless Router processes the data passing through it, so it is not transparent. Use the Special Applications feature to allow the use of Internet applications which do not function correctly.
Wireless Router User Guide 86If this does solve the problem you can 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. A4. 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 "Work-group" does NOT match "workgroup". • Both your PC and the Wireless Access Point must have the same setting for WEP. The default setting for the Wireless Router is disabled, so your wireless station should also have WEP disabled. • If WEP is enabled on the Wireless Router, your PC must have WEP enabled, and the key must match. • If the Wireless Router's Wireless screen is set to. Allow LAN access to selected Wireless Stations only, then each of your Wireless stations must have been selected, or access will be blocked. • To see if radio interference is causing a problem, see if connection is possible when close to the Wireless Access Point. 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 connec-tion speed, you can experiment with the following: • Access Point location. Try adjusting the location and orientation of the Access Point. • 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 Your environment may tend to block transmission between the wireless stations. This will mean high access speed is only possible when close to the Access Point.
Appendix B About Wireless LANs This Appendix provides some background information about using Wireless LANs (WLANs). B1. 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 Sta-tions (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. 87 Access Points can only function in "Infrastructure" mode, and can communicate only with Wireless Stations which are set to "Infrastructure" mode. B2. 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 interfer-ence, 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.) B3. Channels The Wireless Channel sets the radio frequency used for communication.
Wireless Router User Guide 88• 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 channels are available. If using multiple Access Points, it is better if adja-cent 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. B.4 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, 256 Bit Key For 64 Bit encryption, the Key value must match. For 128 Bit encryption, the Key value must match For 256 Bit encryption, the Key value must match WEP Authentication Open System or Shared Key. B.5 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 or 256 Bit).
