Applications
Many advanced networking features are provided by the Barricade:
• Wireless and Wired LAN
The Barricade provides connectivity to wired 10/100 Mbps devices,
and wireless IEEE 802.11b 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.
