Broadband ADSL Router Features
The Broadband ADSL 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
Broadband ADSL Router, using only a single external IP Address. The local (invalid) IP
Addresses are hidden from external sources. This process is called NAT (Network Ad-
dress Translation).

supporting all common ADSL connections.

Router supports all common connection methods.
•
Auto-detection of Internet Connection Method. In most situations, the Broadband
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 (ADSL port) connection, the Broad-
band 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 Broadband ADSL Routers
to establish a VPN connection between them is easy accomplished.
LAN Features
• 4-Port Switching Hub. The Broadband 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 Broadband ADSL Router can act as a
DHCP Server for devices on your local LAN.
Configuration & Management
• Easy Setup. Use your WEB browser from anywhere on the LAN for configuration.
•
Configuration File Upload/Download. Save (download) the configuration data from
the Broadband ADSL Router to your PC, and restore (upload) a previously-saved configu-
