2.Select the Port Triggering radio button.
3.Clear the Disable Port Triggering check box if it is selected.
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 WiFi DSL modem router is retained even though it is not used.
4.In the Port Triggering Timeout field, enter a value up to 9999 minutes.
This value controls the inactivity timer for the designated inbound ports. The inbound ports close when the inactivity time expires. This closure is required because the WiFi DSL modem router cannot be sure when the application has terminated.
