1 Chapter 1 Introduction This Chapter provides an overview of the Wireless Router's features and capabilities. Congratulations on the purchase of your new Wireless Router. The Wireless Router is a multi-function device providing the following services: • Wireless LAN Access Point for equipment compliant with the IEEE802.11b (DSSS) specifications. • Shared Broadband Internet Access for all LAN users. • 4-Port Switching Hub for 10BaseT or 100BaseT connections. • Network Printer - LAN users can share the printer attached to the Wireless Router. Figure 1: Wireless Router 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 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 Address Transla-tion). • 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. • PPPoE and PPTP Support. The Internet (WAN port) connection supports PPPoE (PPP over Ethernet) and PPTP (Peer-to-Peer Tunneling Protocol), as well as "Direct Con-nection" type services. 1

Wireless Router User Guide 2 • 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. Wireless Features • Standards Compliant. The Wireless Router complies with the IEEE802.11b (DSSS) specifications for Wireless LANs. • WEP support. Support for WEP (Wired Equivalent Privacy) is included. Both 64 Bit and 128 Bit keys 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. Advanced Internet Functions • Conferencing & Telephony Applications. Internet Telephony and Conferencing applications, which are often difficult to use when behind a Firewall, are supported. • Special Internet Applications. Applications that use non-standard connections or port numbers are normally blocked by the Firewall. The ability to define and allow such ap-plications 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 that 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 Support. VPN (Virtual Private Networking) connections using PPTP and IPSec are transparently supported - no configuration is required. LAN Features • 4-Port Switching Hub. The Wireless 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 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 Router's RIP (Routing Information Protocol) support and built-in static routing table. • Network Printer. The printer attached to the Wireless Router becomes a "Network Printer", available to all Windows and Linux (Unix) clients on your LAN.

Introduction 3 Configuration & Management • Easy Setup. Use your Web browser from anywhere on the LAN for configuration. • 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. Security Features • Password - protected Configuration. Optional password protection is provided to prevent unauthorized users from modifying the configuration data and settings. • 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. Package Contents The following items should be included: • Wireless Router • Wireless Antenna • Power Adapter • Quick Installation Guide • CD-ROM containing the on-line manual and Printer Port Driver for Windows® If any of the above items are damaged or missing, please contact your dealer immediately.

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).

Setup 15 LAN Screen Use the LAN link on the main menu to reach the LAN screen. An example screen is shown below: Figure 5: 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") net-works. 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 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. 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.

Wireless Router User Guide 16 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). • 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 Con-figuration for the procedure to check these settings.

Setup 17 Wireless Screen The Wireless Access Point settings must match the other Wireless stations. To change the 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 6: 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 Identifier). • 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.

Wireless Router User Guide 18 WEP data encryption • WEP (Wired Equivalent Privacy) status will display "Enabled" or "Disabled", depending on whether WEP is being used. If used, data is Encrypted before being transmitted, making communication more secure. • Click the "Configure WEP" button to access the WEP sub-screen, and view or change the WEP settings. Access Point Allow LAN access by … • All Wireless Stations - All wireless stations can use the access point to access your LAN. • Selected Wireless stations only - Only selected wireless stations can access your LAN. To select the required wireless stations, click the "Select Stations" button.

Check your Wireless card's documentation to see what method to use. Some Wireless cards do not support both methods. Encryption Off • If OFF (default), data is NOT encrypted before being transmitted. 64 Bit Encryption • If selected, data is encrypted, using the default key, before being transmitted. The receiving station must be set to use 64 Bit Encryp-tion, and have the same Key value in the same position in its key table. Otherwise, it will not be able to decrypt the data. • Default Key - select the key you wish to be the default. Transmitted data is ALWAYS encrypted using the Default Key; the other Keys are for decryption only. • Key Table: • This table is used when Encrypting and Decrypting data. All stations, including this Access Point, always transmit data en-crypted using their default key. The key number (1, 2, 3, 4) is also transmitted. The receiving station will use the key number (1, 2, 3, 4) to determine which key value to use for decryption. If the key value does not match the transmitting station, de-cryption will fail. • The easiest way to ensure there are no problems is to have every Station, including the Access Point, use the same key

Wireless Router User Guide 20 table (all entries identical). 128 Bit Encryption • If selected, data is encrypted using the key before being transmit-ted. The receiving station must be set to use 128 Bit Encryption, and have the same Key value. Otherwise, it will not be able to de-crypt the data. • Keys - Enter the key values you wish to use. Other stations must have the same key values. Password Screen The password screen allows you to assign a password to the Wireless Router. Figure 8: Password Screen Once you have assigned a password to the Wireless Router (on the Password screen above) you will be prompted for the password when you connect, as shown below. (If no password has been set, this dialog will not appear.)

Advanced Features 51 Figure 30: Advanced Internet Screen Conferencing & Telephony 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 following Conferencing & Telephony applications: • CUseeME • ICQ • ICU II (ICU 2) • Internet Phone • mIRC • MS NetMeeting • Yahoo Messenger If this problem arises, you can use this screen to set which PC should receive an incoming connection, as described below.

Wireless Router User Guide 52 Conferencing & Telephony Select an Application This lists applications which may generate incoming connections, where the destination (on your local LAN) is unknown. Send incoming calls to This lists the PCs on your LAN. • For each application listed above, you can choose a destina-tion PC. • If necessary, you can add PCs manually, using the PC Data-base option on the advanced menu. • 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

Advanced Features 53 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 dif-ferent 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 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 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. 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 almo st 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.

Wireless Router User Guide 54 URL Filter The URL Filter allows you to block access to undesirable Web sites. • To use this feature, you must define "filter strings". If the "filter string" appears in a re-quested 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.

Wireless Router User Guide 56 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. DSL/CableRouterWeb Server FTP ServerInternetRemote PC Remote PCUsing Web Server Using FTP Server(http://203.70.212.52)203.70.212.52192.168.254.254(192.168.254.10) (192.168.254.20)(LAN IP Address)(WAN IP Address)(ftp://203.70.212.52) Figure 33: 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 con-nect 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 57 Virtual Servers Screen The Virtual Servers screen is reached by the Virtual Servers link on the Advanced screen. An example screen is shown below.

Advanced Features 59 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. Dynamic DNS This free service is very useful when combined with the Virtual Server feature. It allows Inter-net 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.

Advanced Features 61 Remote Management This feature allows you to manage the Wireless Router via the Internet. An example screen is shown below. Figure 36: 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 recommended). 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 Address 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 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.

Wireless Router User Guide 62 Access Control This feature is accessed by the Access Control link on the Advanced menu. Overview The Access Control feature allows administrators to restrict Internet Access by individual PCs. With the default settings, everyone has unrestricted Internet access. To use this feature: 1. Set the desired restrictions on the "Default" group. All PCs are in the "Default" group unless explicitly moved to another group. 2. Set the desired restrictions on the other groups ("Group 1", "Group 2", "Group 3" and "Group 4") as needed. 3. Assign PCs to the groups as required. Restrictions are imposed by blocking "Services", or types of connections. All common Services are pre-defined. If required, you can also define your own Services. Access Control Log To check the operation of the Access Control feature, an Access Control Log is provided. Click the View Log button on the Access Control screen to view this log. This log shows attempted Internet accesses which have been blocked by the Access Control function. Data shown in this log is as follows: Date/Time Date and Time of the attempted access.

68 Chapter 7 Advanced Configuration This Chapter explains the settings available via the Advanced configuration section of the "Advanced" menu. 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 "Virtual 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, including DNS and UPnP. Printer Configure Logical Printers for use under Unix 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. Security Firewall settings. Note: The screens shown below are identical for all Wireless Routers; therefore, some screen-shots are shared between multiple user manuals. 7

Advanced Configuration 69 PC Database Screen 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. An example PC Database screen is shown below. Figure 41: PC Database Screen • 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 required. Data - PC Database Screen PC Database PCs This lists all current entries. Data displayed is name (IP Address) type. For this model, the "type" will either be "LAN" or "WLAN" (Wireless 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.

Wireless Router User Guide 70 Delete Delete the selected PC from the list. This should be done in 2 situations: • 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 Configuration 71 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 42: 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 Firmware Upgrade using TFTP • If enabled, TFTP (Trivial FTP) can be used to upgrade the firmware 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. Allow Configura-tion... • If checked, then UPnP users can change the configuration. • If Disabled, UPnP users can only view the configuration. 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.

Wireless Router User Guide 72 Printer Port Printer Port configuration is only required if using LPD printing under Linux or Unix. Otherwise, these settings are ignored. Under LPD, the Wireless Router supports 3 "Logical Printers". Figure 43: Printer Port Screen Logical Printers No (L1, L2, L3) There are 3 Logical Printers (Ports), named L1, L2, and L3. These names can not be changed, and must be used when select-ing the logical printer from your Unix system. Pre-string (HEX) Enter (in HEX) the series of printer commands to be sent to the attached printer BEFORE each print job. Post-string (HEX) Enter (in HEX) the series of printer commands to be sent to the attached printer AFTER each print job. LF to CR/LF If checked, Unix-style LF (line feed) characters at the end of each line will be converted to CR/LF (carriage return/line feed) pairs, as used in MSDOS and Windows.

Advanced Configuration 73 MAC Address The MAC (hardware) address is a low-level network identifier. It may be called "MAC Address", "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 Inter-net (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 44: 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". If the MAC address is changed, the Wireless Router must be restarted.

Wireless Router User Guide 74 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 ig-nore 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 Wireless 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 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 75 Figure 45: 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. Properties • 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 seg-ment. 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 seg-ment.) • 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.

Wireless Router User Guide 76 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 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.

Wireless Router User Guide 78 Security The security screen is accessed by the Security option on the Advanced menu. Figure 47: 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. • The Wireless Router 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.

Advanced Configuration 79 Options Respond to ICMP (ping) 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 (Vir-tual 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 Net-works). • If checked, L2TP connections are allowed. • If not checked, L2TP connections are blocked.

80 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 Router and some possible solutions to them. If you follow the suggested steps and the Wire-less Router still does not function properly, contact your dealer for further advice. 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. Check the LEDs for port status. • 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 192.168.254.1 to 192.168.254.253 and thus com-patible with the Wireless Router's default IP Address of 192.168.254.254. 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. 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. A

$Appendix A - Troubleshooting 81 Solution 2: The Wireless Router processes the data passing through it, so it is not transparent. Use the Special Applications feature to allow the use of Internet applica-tions which do not function correctly. If this does solve the problem you can use the DMZ function. This should work with almost every application, but: • It is a security risk, since the firewall is disabled for the DMZ PC. • Only one (1) PC can use this feature. Printing Problem 1: When I tried to install the Printing software for Peer-to-Peer printing, I received an error message and the installation was aborted.. Solution 1: This may be caused by an existing installation of the printer port software. Before attemp ting another installation: • Remove the existing installation • Restart your PC To remove an existing printer port installation: 1. Open Start - Settings - Control Panel - Add/Remove Programs 2. Look for an entry with a name like "Shared Port", "Shared Printer Port", "Print Server Driver" or "Print Server Port". 3. Select this item, click "Add/Remove", and confirm the deletion. Problem 2: I am using Windows 95, and the Printing software installed and ran, but when I selected a port on a Wireless Router and clicked "Add", the printer was not installed. Solution 2: Try installing the printer using the standard Windows tools, as follows: 1. Start the Add Printer Wizard. 2. Select Network Printer when prompted "How is the printer attached to your Computer?", and click Next. 3. When prompted for the Network Path or Queue, enter a dummy value such as \\123, as shown below. (Do NOT select Yes for "Do you print for MS-DOS programs?")$
