Introduction
This Chapter provides an overview of the Wireless ADSL Router's features
and capabilities.
Congratulations on the purchase of your new Wireless ADSL Router. The Wireless ADSL
Router is a multi-function device providing the following services:
•ADSL Modem.
•Shared Broadband Internet Access for all LAN users.
•Wireless Access Point for 802.11b and 802.11g Wireless Stations.
•4-Port Switching Hub for 10BaseT or 100BaseT connections.
Figure 1: Wireless ADSL Router
Wireless ADSL Router Features
The Wireless ADSL Router incorporates many advanced features, carefully designed to 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
(invalid) IP Addresses are hidden from external sources. This process is called NAT (Net-
work Address Translation).
•Built-in ADSL Modem. The Wireless ADSL Router has a built-in ADSL modem,
supporting all common ADSL connections.
•IPoA, PPPoE, PPPoA, Direct Connection Support. The Wireless ADSL Router
supports all common connection methods.

•Auto-detection of Internet Connection Method. In most situations, the Wireless
ADSL Router can test your ADSL and Internet connection to determine the connection me-
thod used byyour ISP.
•Fixed or Dynamic IP Address. On the Internet (ADSL 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.
•Port Triggering. This feature, also called Special Applications, allows you to use
Internet applications which normally do not function when used behind a firewall.
•Port Forwarding. 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 dynam-
ic IP address which changes every time you connect.
•URL Filter. Use the URL Filter to block access to undesirable Web sites by LAN users.
•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.
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 anydata before transmission, providing pro-
tection against snoopers.
•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.
•WPS Support. WPS (Wi-Fi Protected Setup) can simplify the process of connecting any
device to the wireless network by using the push button configuration (PBC) on the Wire-
less Access Point, or entering a 8-digit PIN code if there's no button.

Introduction

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 configu-
ration.
•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-802.1x, WPA2-802.1x and WEP and Wireless access
control by MAC address 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 bandwidth
and so many resources that Internet access becomes unavailable. The Wireless ADSL Rou-
ter incorporates protection against DoS attacks.

The default value 255.255.255.0 is standard for small (class "C")
networks. For other networks, use the Subnet Mask for the LAN
segment to which the Wireless ADSL Router is attached (the same
value as the PCs on that LAN segment).
DHCP Server
•If Enabled, the Wireless ADSL Router will allocate IP Addresses
to PCs (DHCP clients) on your LAN when they start up. The de-
fault (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. Enter the desired value for the Lease Time, which
should be between 1 and 7.
See the following section for further details on using DHCP.
