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.
•
Security
The Barricade supports security features that deny Internet access to
specified users, or filter all requests for specific services that the
administrator does not want to serve. The Barricade’s firewall also
blocks common hacker attacks, including IP Spoofing, Land Attack,
Ping of Death, IP with zero length, Smurf Attack, UDP port
loopback, Snork Attack, TCP null scan, and TCP SYN flooding.
