Section 5: Special Applications

When you use Internet applications which have non-standard connections or port numbers, you may find that they do not function correctly because they are blocked by the Twin WAN Gateway firewall. You can define the application as a Special Application in order to make it work.

Note: The terms Incoming and Outgoing on this screen refer to traffic from the client (PC) viewpoint.

Using a Special Application on you PC

  • Once the Special Applications console is configured correctly, you can use the application on your PC normally. Remember that only one (1) PC can use each Special application at any time.

  • When 1 PC is finished using a defined special application, there may need to be a Time-out period before another PC can use the same special application.

  • In the event a defined special application will not function correctly, use the DMZ feature if required.
