A PPLICATIONS
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 a
DSL 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.
◆ 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.
◆ DMZ Host Support — Allows a networked computer to be fully
exposed to the Internet. This function is used when NAT and firewall
security prevent an Internet application from functioning correctly.
