I NTRODUCTION
Congratulations on your purchase of the VoIP ADSL Router, hereafter
referred to as the “Router.” We are proud to provide you with a powerful
yet simple communication device for connecting your local area network
(LAN) to the Internet. For those who want to surf the Internet in the most
secure way, this router provides a convenient and powerful solution. The
Router also enables service providers to provide their residential and small
office home office (SOHO) customers with high-quality VoIP service
using traditional analog telephones and fax machines.
About the Router
The Router provides Internet access to multiple users by sharing a
single-user account. Support is provided for both wired and wireless
devices. This device also provides wireless security via Wired Equivalent
Privacy (WEP), Wi-Fi Protected Access (WPA) and WPA2 encryption, and
MAC address filtering. It is simple to configure and can be up and running
in minutes.

• On-board IEEE 802.11b/g wireless access point
• DHCP for dynamic IP configuration, and DNS Proxy/Relay for
domain name mapping
• Firewall with Stateful Packet Inspection, client privileges, intrusion
detection and NAT
• NAT also enables multi-user Internet access via a single user account,
and virtual server functionality (providing protected access to Internet
services such as web, FTP, email and Telnet)
• User-definable application sensing tunnel supports applications
requiring multiple connections
• Easy setup through a web browser on any operating system that
supports TCP/IP
• QoS allows you to optimize voice quality by prioritizing VoIP over
data traffic

A PPLICATIONS

Applications
Many advanced networking features are provided by the Router:
• Wireless and Wired LAN
The Router provides connectivity to 10/100 Mbps devices, and
wireless IEEE 802.11b/g compatible devices, making it easy to create
a network in small offices or homes.
• Internet Access
This device supports Internet access through an ADSL connection.
Since many DSL providers use PPPoE or PPPoA to establish
communications with end users, the Router includes built-in clients
for these protocols, eliminating the need to install these services on
your computer.
• Shared IP Address
The Router provides Internet access for up to 253 users via a single
shared IP address. Using only one ISP account, multiple users on your
network can access the Internet at the same time.
• Virtual Server
If you have a fixed IP address, you can set the Router to act as a virtual
host for network address translation. Remote users access various
services at your site using a constant IP address. Then, depending on
the requested service (or port number), the Router can route the
request to the appropriate server (at another internal IP address). This
secures your network from direct attack by hackers, and provides
more flexible management by allowing you to change internal IP
addresses without affecting outside access to your network.

I NTRODUCTION
1-4
• DMZ Host Support
Allows a networked computer to be fully exposed to the Internet.
This function is used when NAT and firewall security prevent an
Internet application from functioning correctly.
•Security
The Router supports security features that deny Internet access to
specified users, or filter all requests for specific services that the
administrator does not want to serve. The Router’s firewall also blocks
common hacker attacks, including IP Spoofing, Land Attack, Ping of
Death, IP with zero length, Smurf Attack, UDP port loopback, Snork
Attack, TCP null scan, and TCP SYN flooding.
• Internet Calling
You can make telephone calls using the Internet.
