APPLICATIONS

Virtual Server

If you have a fixed IP address, you can set up the Wireless 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 Wireless 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.

User-Definable Application Sensing Tunnel

You can define special applications that require multiple connections such as Internet gaming, videoconferencing, and Internet telephony. The Wireless Barricade can then sense the application type and open a multi-port tunnel for it.

DMZ Host Support

Allows a networked computer to be fully exposed to the Internet. This function is used when the special application sensing tunnel feature is insufficient to allow an application to function correctly.

Security

The Wireless Barricade supports security features that can deny Internet access to specified users, or filter all requests for specific services the administrator does not want to serve. The Wireless Barricade’s firewall can also block 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.
