Applications - SMC Networks Barricade Plus SMC7004FW User Manual

Applications

Many advanced applications are provided by the Barricade Plus, such
as:
• LAN Access
The Barricade Plus 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, or Cable
connection. Since many DSL providers use PPPoE to establish
communications with end users, the Barricade Plus includes a
built-in client for this protocol, eliminating the need to install
this service on your computer.
• Shared IP Address
The Barricade Plus 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 Plus
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 Plus 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.
