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 connection speed up to 300 Mbps. This router is fully 
compliant with specifications defined in IEEE 802.11b, IEEE 
802.11g and IEEE 802.11n draft v2.0 standards, making it easy to 
create a network in small offices or homes.
• Internet Access
This device allows you to share your Cable/xDSL Internet 
connection. Since many ADSL providers use PPPoE to establish 
communications with end users, the Barricade includes a built-in 
client for this protocol, 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.
