Regulatory Approvals FCC Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communica-tions. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures: Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. To assure continued compliance, any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. (Example - use only shielded interface cables when connecting to computer or peripheral devices). FCC Radiation Exposure Statement This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20 centimeters between the radiator and your body. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) This device must accept any interference received, including interference that may cause undesired operation. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. The antennas used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter. Channel The Wireless Channel sets the radio frequency used for communication. •Access Points use a fixed Channel. You can select the Channel used. This allows you to choose a Channel which provides the least interference and best performance. In the USA and Canada, 11 channel are available. If using multiple Access Points, it is better if adjacent Access Points use different Channels to reduce interference. • In "Infrastructure" mode, Wireless Stations normally scan all Channels, looking for an Access Point. If more than one Access Point can be used, the one with the strongest signal is used. (This can only happen within an ESS.) • If using "Ad-hoc" mode (no Access Point), all Wireless stations should be set to use the same Channel. However, most Wireless stations will still scan all Channels to see if there is an existing "Ad-hoc" group they can join.CAUTION:1) To comply with FCC RF exposure compliance requirements, a separationdistance of at least 20 cm must be maintained between the antenna of thisdevice and all persons.2) This transmitter must not be co-located or operating in conjunction withany other antenna or transmitter.

1 Chapter 1 Introduction This Chapter provides an overview of the Wireless ADSL Router's features and capabilities. Congratulations on the purchase of your new Wireless ADSL Router. The Wireless ADSL Router is a multi-function device providing the following services: • ADSL Modem. • Shared Broadband Internet Access for all LAN users. • Wireless Access Point for 802.11b and 802.11g Wireless Stations. • VPN Gateway to allow secure VPN connections over the Internet. • 4-Port Switching Hub for 10BaseT or 100BaseT connections. Figure 1: Wireless ADSL Router Wireless ADSL Router Features The Wireless ADSL Router incorporates many advanced features, carefully designed to pro-vide sophisticated functions while being easy to use. Internet Access Features • Shared Internet Access. All users on the LAN or WLAN can access the Internet through the Wireless ADSL Router, using only a single external IP Address. The local (in-valid) IP Addresses are hidden from external sources. This process is called NAT (Network Address Translation). • Built-in ADSL Modem. The Wireless ADSL Router has a built-in ADSL modem, supporting all common ADSL connections. 1
Wireless ADSL Router User Guide 2 • IPoA, PPPoE, PPPoA, Direct Connection Support. The Wireless ADSL Router supports all common connection methods. • Auto-detection of Internet Connection Method. In most situations, the Wireless ADSL Router can test your ADSL and Internet connection to determine the connection method used by your ISP. • Fixed or Dynamic IP Address. On the Internet (WAN port) connection, the Wireless ADSL Router supports both Dynamic IP Address (IP Address is allocated on connection) and Fixed IP Address. Advanced Internet Functions • Application Level Gateways (ALGs). Applications which use non-standard connec-tions 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. • Special Applications. This feature, also called Port Triggering, allows you to use Internet applications which normally do not function when used behind a firewall. • Virtual Servers. This feature allows Internet users to access Internet servers on your LAN. The required setup is quick and easy. • Dynamic DNS Support. DDNS, when used with the Virtual Servers feature, allows users to connect to Servers on your LAN using a Domain Name, even if you have a dy-namic IP address which changes every time you connect. • URL Filter. Use the URL Filter to block access to undesirable Web sites by LAN users. • Firewall. As well as the built-in firewall to protect your LAN, you can define Firewall Rules to determine which incoming and outgoing traffic should be permitted. • Scheduling. Both the URL Filter and Firewall rules can be scheduled to operate only at certain times. This provides great flexibility in controlling Internet -bound traffic. • Logs. Define what data is recorded in the Logs, and optionally send log data to a Syslog Server. Log data can also be E-mailed to you. • VPN Pass through Support. PCs with VPN (Virtual Private Networking) software using PPTP, L2TP and IPSec are transparently supported - no configuration is required. VPN Features • IPSec Support. IPSec is the most common protocol. • Easy Configuration. The configuration required to allow 2 Wireless ADSL Routers to establish a VPN connection between them is easy accomplished. Wireless Features • Standards Compliant. The Wireless ADSL Router complies with the IEEE802.11g (DSSS) specifications for Wireless LANs. • Supports both 802.11b and 802.11g Wireless Stations. The 802.11g standard provides for backward compatibility with the 802.11b standard, so both 802.11b and 802.11g Wireless stations can be used simultaneously. • Speeds to 54Mbps. All speeds up to the 802.11g maximum of 54Mbps are supported. • WEP support. Support for WEP (Wired Equivalent Privacy) is included. Key sizes of 64 Bit and 128 Bit are supported. WEP encrypts any data before transmission, providing pro-tection against snoopers.
Introduction 3 • WPA-PSK support. Like WEP, WPA-PSK encrypts any data before transmission, providing protection against snoopers. The WPA-PSK is a later standard than WEP, and provides both easier configuration and greater security than WEP. • Wireless MAC Access Control. The Wireless Access Control feature can check the MAC address (hardware address) of Wireless stations to ensure that only trusted Wireless Stations can access your LAN. • Simple Configuration. If the default settings are unsuitable, they can be changed quickly and easily. LAN Features • 4-Port Switching Hub. The Wireless ADSL Router incorporates a 4-port 10/100BaseT switching hub, making it easy to create or extend your LAN. • DHCP Server Support. Dynamic Host Configuration Protocol provides a dynamic IP address to PCs and other devices upon request. The Wireless ADSL Router can act as a DHCP Server for devices on your local LAN and WLAN. Configuration & Management • Easy Setup. Use your WEB browser from anywhere on the LAN or WLAN for configura-tion. • Configuration File Upload/Download. Save (download) the configuration data from the Wireless ADSL Router to your PC, and restore (upload) a previously-saved configura-tion file to the Wireless ADSL Router. • Remote Management. The Wireless ADSL Router can be managed from any PC on your LAN or Wireless LAN. And, if the Internet connection exists, it can also (optionally) be configured via the Internet. • Network Diagnostics. You can use the Wireless ADSL Router to perform a Ping or DNS lookup. Security Features • Password - protected Configuration. Password protection is provided to prevent unauthorized users from modifying the configuration data and settings. • Wireless LAN Security. WPA-PSK, WEP and Wireless access control by MAC ad-dress are all supported. The MAC-level access control feature can be used 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 ADSL Router. • Firewall. All incoming data packets are monitored and all incoming server requests are filtered, thus protecting your network from malicious attacks from external sources. • Protection against DoS attacks. DoS (Denial of Service) attacks can flood your Internet connection with invalid packets and connection requests, using so much band-width and so many resources that Internet access becomes unavailable. The Wireless ADSL Router incorporates protection against DoS attacks.

Wireless ADSL Router User Guide 12 Common Connection Types Type Details ISP Data required Dynamic IP Address Your IP Address is allocated automatically, when you connect to you ISP. a) ADSL parameters (VPI and VCI) may be required, if they cannot be detected automatically. b) Some ISP's may require you to use a particular Hostname or Domain name, or MAC (physical) address. Static (Fixed) IP Address Your ISP allocates a permanent IP Address to you. Usually, the connection is "Al-ways on". a) ADSL parameters (VPI and VCI) may be required, if they cannot be detected automatically. b) IP Address allocated to you, and related information, such as Network Mask, Gateway IP address, and DNS address. PPPoE, PPPoA You connect to the ISP only when required. The IP address is usually allocated automatically. a) ADSL parameters (VPI and VCI) may be required, if they cannot be detected automatically. b) User name and password are always required. c) If using a Static (Fixed) IP address, you need the IP address and related information (Network Mask, Gateway IP address, and DNS address) IPoA (IP over ATM) Normally, the connection is "Always on". a) ADSL parameters (VPI and VCI) may be required, if they cannot be detected automatically. b) IP Address allocated to you, and related information, such as Network Mask, Gateway IP address, and DNS address.
Setup 13 Home 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 Main Menu The main menu, on the left, contains links to the most-commonly used screen. To see the links to the other available screens, click "Advanced" or "Administration". The main menu also contains two (2) buttons: • Log Out - When finished, you should click this button to logout. • Restart - Use this if you wish to restart the Wireless ADSL Router. Note that restarting the Router will break any existing connections to or through the Router. Navigation & Data Input • Use the menu bar on the left 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.
Wireless ADSL Router User Guide 14 LAN Screen Use the LAN link on the main menu to reach the LAN screen. An example screen is shown below. Figure 6: LAN Screen Data - LAN Screen TCP/IP IP Address IP address for the Wireless ADSL Router, as seen from the local LAN. Use the default value unless the address is already in use or your LAN is using a different IP address range. In the latter case, enter an unused IP Address from within the range used by your LAN. Subnet Mask The default value 255.255.255.0 is standard for small (class "C") net-works. For other networks, use the Subnet Mask for the LAN segment to which the Wireless ADSL Router is attached (the same value as the PCs on that LAN segment). DHCP Server • If Enabled, the Wireless ADSL Router will allocate IP Addresses to PCs (DHCP clients) on your LAN when they start up. The default (and recommended) value is Enabled. • If you are already using a DHCP Server, this setting must be Disabled, and the existing DHCP server must be re-configured to treat the Wireless ADSL Router as the default Gateway. See the following section for further details. • The Start IP Address and Finish IP Address fields set the values used by the DHCP server when allocating IP Addresses to DHCP clients. This range also determines the number of DHCP clients supported. See the following section for further details on using DHCP. DHCP What DHCP Does A DHCP (Dynamic Host Configuration Protocol) Server allocates a valid IP address to a DHCP Client (PC or device) upon request. • The client request is made when the client device starts up (boots). • The DHCP Server provides the Gateway and DNS addresses to the client, as well as allocating an IP Address.
Setup 15 • The Wireless ADSL Router can act as a DHCP server. • Windows 95/98/ME and other non-Server versions of Windows will act as a DHCP client. This is the default Windows setting for the TCP/IP network protocol. However, Windows uses the term Obtain an IP Address automatically instead of "DHCP Client". • You must NOT have two (2) or more DHCP Servers on the same LAN segment. (If your LAN does not have other Routers, this means there must only be one (1) DHCP Server on your LAN.) Using the Wireless ADSL Router's DHCP Server This is the default setting. The DHCP Server settings are on the LAN screen. On this screen, you can: • Enable or Disable the Wireless ADSL Router's DHCP Server function. • Set the range of IP Addresses allocated to PCs by the DHCP Server function. You can assign Fixed IP Addresses to some devices while using DHCP, provided that the Fixed IP Addresses are NOT within the range used by the DHCP Server. Using another DHCP Server You can only use one (1) DHCP Server per LAN segment. If you wish to use another DHCP Server, rather than the Wireless ADSL Router's, the following procedure is required. • Disable the DHCP Server feature in the Wireless ADSL Router. This setting is on the LAN screen. • Configure the DHCP Server to provide the Wireless ADSL Router's IP Address as the Default Gateway. To Configure your PCs to use DHCP This is the default setting for TCP/IP for all non-Server versions of Windows. See Chapter 4 - Client Configuration for the procedure to check these settings.
Wireless ADSL Router User Guide 16 Wireless Screen The Wireless ADSL Router's settings must match the other Wireless stations. Note that the Wireless ADSL Router will automatically accept both 802.11b and 802.11g con-nections, and no configuration is required for this feature. To change the Wireless ADSL 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 Select the correct domain for your location. It is your responsibility to ensure: • That the Wireless ADSL Router is only used in domains for which is licensed. • That you select the correct domain, so that only the legal channels for that domain can be selected. Station name This is the same as the "Device Name" for the Wireless ADSL Router. 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.
Setup 17 Options Mode Select the desired mode: • g & b - Both 802.11.g and 802.11b Wireless stations will be able to use the Wireless ADSL Router. • g only - Only 802.11g Wireless stations can use the Wireless ADSL Router. • b only - Only 802.11b connections are available. 802.11g Wireless Stations will only be able to use the Wireless ADSL Router if they are fully backward-compatible with the 802.11b standard. 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. Broadcast SSID If enabled, the Wireless ADSL Router will broadcast its SSID. This allows PCs and other wireless stations to detect this Access Point and use the correct SSID. If disabled, PC users will have to manually enter the SSID and other details of the wireless interface before they can connect to this Access Point. Wireless Security Current Setting The current Wireless security is displayed. The default value is dis-abled. Configure Button Click this button to access the Wireless security sub-screen, and view or change the settings. See the following section for details. Access Point Enable Wireless Access Point Enable this if you want to use Wireless Access Point function. If disabled, no Wireless stations can use the Access Point function, and all connections must be make via the wired LAN. Allow access by … Use this feature to determine which Wireless stations can use the Access Point. The options are: • All Wireless Stations - All wireless stations can use the access point, provided they have the correct SSID and security settings. • Trusted Wireless stations only - Only wireless stations you designate as "Trusted" can use the Access Point, even if they have the correct SSID and security settings. This feature uses the MAC address to identify Wireless stations. The MAC address is a low-level network identifier which is unique to each PC or network device. To define the trusted wireless stations, use the "Set Stations" but-ton. Set Stations Button Click this button to manage the trusted PC database.
Wireless ADSL Router User Guide 18 Wireless Security This screen is accessed by clicking the "Configure" button on the Wireless screen. There are 3 options for Wireless security: • Disabled - no data encryption is used. • WEP - data is encrypted using the WEP standard. • WPA-PSK - data is encrypted using the WPA-PSK standard. This is a later standard than WEP, and provides much better security than WEP. If all your Wireless stations support WPA-PSK, you should use WPA-PSK rather than WEP. WEP Wireless Security Figure 8: WEP Data - WEP Screen WEP Data Encryption WEP Data En-cryption Select the desired option, and ensure the Wireless Stations use the same setting. • 64 Bit - data is encrypted, using the default key, before being transmitted. You must enter at least the default key. For 64 Bit En-cryption, the key size is 10 chars in HEX (0~9 and A~F). • 128 Bit - data is encrypted, using the default key, before being transmitted. You must enter at least the default key. For 128 Bit En-cryption, the key size is 26 chars in HEX (0~9 and A~F). Authentication Type Normally, this should be left at the default value of "Automatic". If changed to "Open System" or "Shared Key", ensure that your Wireless Stations use the same setting. 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. You must enter a Key Value for the Default Key.
Setup 19 Key Value Enter the key value or values you wish to use. The Default Key is required, the other keys are optional. Other stations must have the same key. Passphrase If desired, you can generate a key from a phrase, instead of entering the key value directly. Enter the desired phrase, and click the "Generate Keys" button. WPA-PSK Wireless Security Figure 9: WPA-PSK Data - WPA-PSK Screen Security System WPA-PSK Like WEP, data is encrypted before transmission. WPA is more secure than WEP, and should be used if possible. WPA-PSK is the version of WPA, which does NOT require a Radius Server on your LAN. PSK Enter the PSK (network key). Data is encrypted using a key derived from the network key.

Router Both the ADSL Modem and the Router features are operational. In this mode, this device can provide shared Internet Access to all your LAN users. Also, by default, it acts a DHCP Server, providing an IP address and related infor-mation to all Wireless and LAN users. Modem Only the ADSL Modem component is operational. • All Router features are disabled. This device is "transparent" - it does not perform any operations or make any changes to the network traffic passing through it. • You need to have a DHCP Server on your LAN to provide IP addresses to the Wireless clients using this Access Point. • All traffic received on either the Wireless or LAN interface will be sent over the ADSL connection. Notes: • Generally, you should NOT use modem mode. Only select this mode if you are sure this is what you want. • After changing the mode, this device will restart, which will take a few seconds. The menu will also change, depending on the mode you are in. • The Wireless Access Point can function in either Router or Modem mode. But generally it is not a good idea to combine a Modem with an Access Point, because all data received from the wireless stations will be sent over the modem connection. (Since the modem is transparent, it does not examine the traffic to determine whether the traffic is for the LAN or the WAN.) • For details on using Modem Mode, see Chapter 8.
24 Chapter 4 PC Configuration This Chapter details the PC Configuration required on the local ("Internal") LAN. Overview For each PC, the following may need to be configured: • TCP/IP network settings • Internet Access configuration • Wireless configuration Windows Clients This section describes how to configure Windows clients for Internet access via the Wireless ADSL Router. The first step is to check the PC's TCP/IP settings. The Wireless ADSL 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 ADSL Router settings, and the default Win-dows TCP/IP settings, no changes need to be made. • By default, the Wireless ADSL 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 ADSL Router • The DNS should be set to the address provided by your ISP. If your LAN has a Router, the LAN Administrator must re-configure the Router itself. Refer to Chapter 8 - Advanced Setup for details. 4
