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 802.11g 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 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.
