To configure port triggering, you need to know which inbound ports the application needs,
and the number of the outbound port that will trigger the opening of the inbound ports.
Usually, you can determine this information by contacting the publisher of the application or
the relevant user groups or news groups.

To set up port triggering:
Select Advanced > Advanced Setup > Port Forwarding/Port Triggering.
1.
Select the Port Triggering radio button to display the port triggering information.
2.
Clear the Disable Port Triggering check box if it is selected.
3.
Note: If the Disable Port Triggering check box is selected after you configure
port triggering, port triggering is disabled. However, any port triggering
configuration information you added to the router is retained even though it is
not used.
In the Port Triggering Timeout field, enter a value up to 9999 minutes.
4.
This value controls the inactivity timer for the designated inbound ports. The inbound
ports close when the inactivity time expires. This is required because the router cannot be
sure when the application has terminated.
