54Mbps 802.11g ADSL Firewall Modem Router Features
The 54Mbps 802.11g ADSL Firewall Modem 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 54Mbps 802.11g ADSL Firewall Modem 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 Translation).
•Built-in ADSL Modem. The 54Mbps 802.11g ADSL Firewall Modem Router has a
built-in ADSL modem, supporting all common ADSL connections.
•IPoA, PPPoE, PPPoA, BPA, Direct Connection Support. The 54Mbps 802.11g
ADSL Firewall Modem Router supports all common connection methods.
•Auto-detection of Internet Connection Method. In most situations, Tthe 54Mbps
802.11g ADSL Firewall Modem Router can test your ADSL and Internet connection to de-
termine the connection method used by your ISP. This will require ISP or network service
provider to enable F5 function in the CO side.
•Fixed or Dynamic IP Address. On the Internet (ADSL port) connection, the 54Mbps
802.11g ADSL Firewall Modem 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 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.
•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.
Wireless Features
•Standards Compliant. The 54Mbps 802.11g ADSL Firewall Modem 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 speedsup to the 802.11g maximum o f 54Mbps are supported.

Introduction
3
•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.
•WPA support. Support for WPA is included. WPA is more secure than WEP, and should
be used if possible. Both TKIP and AES encryption methods are supported.
•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 54Mbps 802.11g ADSL Firewall Modem Router incorpo-
rates 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 54Mbps 802.11g ADSL Firewall
Modem 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 54Mbps 802.11g ADSL Firewall Modem Router to your PC, and restore (upload) a
previously-saved configuration file to the 54Mbps 802.11g ADSL Firewall Modem Router.
•Remote Management. The 54Mbps 802.11g ADSL Firewall Modem Router can be
managed from any PC on your LAN or Wireless LAN. And, if the Internet connection ex-
ists, it can also (optionally) be configured via the Internet.
•Network Diagnostics. You can use the 54Mbps 802.11g ADSL Firewall Modem 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 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 54Mbps 802.11g ADSL Firewall Modem 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 54Mbps 802.11g
ADSL Firewall Modem Router incorporates protection against DoS attacks.
