I NTRODUCTION
Congratulations on your purchase of the BarricadeTM g Voice ADSL
Router, hereafter referred to as the “Barricade”. 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 VoIP 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 Barricade
The Barricade 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) encryption and MAC address filtering. It is simple to
configure and can be up and running in minutes.
VoIP (Voice over IP)
Using Voice over IP (VoIP), instead of making calls over the regular
telephone network, calls are made over computer (IP) networks, either
through your Internet Service Provider’s connection or through your local
network. Calls made to another Internet telephone, anywhere in the world,
are generally free, while calls made to a regular telephone are generally
much cheaper than traditional long distance calls. The basic steps involved
in VoIP include the conversion of an analog voice signal to digital, the

I NTRODUCTION
1-2
encoding and then compression of the signal into Internet Protocol (IP)
packets. The VoIP Router is equipped with a digital signal processor
(DSP), which segments the voice signal into frames and stores them in
voice packets. These packets are encoded using the industry standard
CODECs, G.711, G.723.3 and G.729.
Features and Benefits
• Intergrated ADSL modem for connecting to ADSL line
• Local network connection via four 10/100 Mbps Ethernet ports
• 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, e-mail, and Telnet)
• VPN pass-through (IPSec-ESP Tunnel mode, L2TP, PPTP)
• User-definable application sensing tunnel supports applications
requiring multiple connections
• Easy setup through a web browser on any operating system that
supports TCP/IP
• Compatible with all popular Internet applications

A PPLICATIONS

Applications
Many advanced networking features are provided by the Barricade:
• Wireless and Wired LAN
The Barricade 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 Barricade includes built-in clients
for these protocols, eliminating the need to install these services on
your computer.
• Shared IP Address
The Barricade 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.
•VirtualServer
If you have a fixed IP address, you can set the Barricade 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 Barricade
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 Barricade 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 Barricade’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.
• Virtual Private Network (VPN)
The Barricade supports three of the most commonly used VPN
protocols — PPTP, L2TP, and IPSec. These protocols allow remote
users to establish a secure connection to their corporate network. If
your service provider supports VPNs, then these protocols can be
used to create an authenticated and encrypted tunnel for passing
secure data over the Internet (i.e., a traditionally shared data network).
The VPN protocols supported by the Barricade are briefly described
below.
• Point-to-Point Tunneling Protocol — Provides a secure tunnel
for remote client access to a PPTP security gateway. PPTP
includes provisions for call origination and flow control required
by ISPs.
• L2TP merges the best features of PPTP and L2F — Like PPTP,
L2TP requires that the ISP’s routers support the protocol.
• IP Security — Provides IP network-layer encryption. IPSec can
support large encryption networks (such as the Internet) by using
digital certificates for device authentication.

Hardware Description
The Barricade contains an integrated ADSL2+ modem and connects to
the Internet or to a remote site using its WAN port. This device can be
connected directly to your PC or to a local area network using any of the
four Fast Ethernet LAN ports.
Access speed to the Internet depends on your service type. Full-rate ADSL
provides up to 8 Mbps downstream and 1 Mbps upstream. G.lite (or
splitterless) ADSL provides up to 1.5 Mbps downstream and 512 kbps
upstream. ADSL2+ Provides up to 24 Mbps downstream and 1.2 Mbps
upstream. However, you should note that the actual rate provided by
specific service providers may vary dramatically from these upper limits.
Data passing between devices connected to your local area network can
run at up to 100 Mbps over the Fast Ethernet ports and 54 Mbps over the
built-in wireless network adapter.
The Barricade includes an LED display on the front panel for system
power and port indications that simplifies installation and network
troubleshooting.
