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 a DSL or cable
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 shares a single IP address with up to 253 users. Using
only one ISP account, multiple users on your network can
simultaneously browse the Internet.
•Virtual Server
If you have a static 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 the static IP address. Then,
depending on the requested service (or port number), the Barricade
routes the request to the appropriate server (at an internal network IP
address). This secures your network from direct attack by hackers, and
provides more flexible management by allowing you to change
internal network IP addresses without affecting outside access to your
network.
