Features and Benefits
•
Local network connection via a 10/100 Mbps Ethernet port
•
DHCP for dynamic IP configuration, and DNS 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)
•
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

Applications
Many advanced networking features are provided by this BARRICADE:
•
Wired and Wireless LAN
The BARRICADE provides connectivity to 10/100 Mbps devices,
and wireless IEEE 802.11g 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 ADSL 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 browse the web at the same time.
•
Virtual Server
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.

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.
WPA/WPA2, WEP, SSID, and MAC filtering provide security over
the wireless network.
•
Virtual Private Network (VPN Pass-through)
The BARRICADE supports three of the most commonly used VPN
protocols – PPTP, L2TP, and IPSec. 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 connects to the Internet or to a remote site using its
WAN RJ-45 port linked to a modem. It also can be connected directly to
your PC or to a local area network using the Fast Ethernet LAN port.
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. 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 port 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.
