• 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.
