Port Trigger

If you use Internet applications which use non-standard connections or port numbers, you may

find that they do not function correctly because they are blocked by the Wireless ADSL

Router's firewall. In this case, you can define the application as a "Port Trigger".

The Port Trigger screen can be reached by clicking the Port Trigger on the screen.

You can then define your Port Trigger. You will need detailed information about the applica-

tion; this is normally available from the supplier of the application.

Also, note that the terms "Incoming" and "Outgoing" on this screen refer to traffic from the

client (PC) viewpoint
