Using a Special Application

∙Configure the Special Applications screen as required.

∙On your PC, use the application normally. Remember that only one (1) PC can use each Special application at any time. Also, when 1 PC is finished using a particular Special Application, there may need to be a "Time-out" before another PC can use the same Spe- cial Application. The "Time-out" period may be up to 3 minutes.

If an application still cannot function cor- rectly, try using the "DMZ" feature.

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 almost any application to be used on the "DMZ PC".

∙The "DMZ PC" will receive all "Unknown" connections and data.

∙If the DMZ feature is enabled, you must select the PC to be used as the "DMZ PC".

∙The DMZ feature can be Enabled and Disabled on the Advanced Internet screen.
