Applications
Many advanced applications are provided by the Barricade, such as:
• LAN Access
The Barricade provides connectivity to 10/100 Mbps devices,
making it easy to create a network in small offices or homes.
• Internet Access
This device supports Internet access through an xDSL, Cable,
ISDN or PSTN connection. Since many DSL providers use
PPPoE to establish communications with end users, the
Barricade includes a built-in client for this protocol,
eliminating the need to install this service on your computer.
• Shared IP Address
The Barricade provides Internet access for up to 253 users
with a 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 up 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.
