DMZ

This feature, if enabled, allows one (1) computer on your LAN to be exposed to all users on the Internet, allowing unrestricted 2-way communication between the "DMZ" PC and other Internet users or Servers.

This allows connection to special-purpose servers, which require proprietary client software, or 2-way user connections such as Video-conferencing, which requires both users to run special software.

To allow unrestricted access, the Firewall in this device is disabled, creating a security risk.

You should use this feature only if the "Special Applications" feature is insuffi- cient to allow an application to function correctly. This feature should be turned ON only when needed, and left OFF the rest of the time.

Configuring the DMZ

Select Advanced Internet from the navigation bar, then DMZ. You will see a screen like the following:
