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 separation
distance of at least 20 cm must be maintained between the antenna of this
device and all persons.
2) This transmitter must not be co-located or operating in conjunction with
any other antenna or transmitter.

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 Accessfor all LAN users.
•Wireless Access Point for 802.11b and 802.11gWireless 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.

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 802.11gmaximum 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 Controlfeature 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.

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 LANscreen. On this screen,
you can:
•Enable or Disable the Wireless ADSL Router'sDHCP 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.
