N300 Wireless ADSL2+ Modem Router DGN2200v3
Note: If you use applications such as multiplayer gaming, peer-to-peer
connections, real-time communications such as instant messaging,
or remote assistance (a feature in Windows XP), you should also
enable Universal Plug and Play (UPnP).
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.
You
can usually determine this information by contacting the publisher of the application or user
groups or news groups.
To enable port triggering:
1. Select Advanced > Port Forwarding/Port T
riggering to display the Port
Forwarding/Port Triggering screen.
2. Select the Port T
riggering radio button to display the port triggering information.
3. Clear the Disable Port Triggering check box.
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.
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 is required because the router cannot be sure when the
application has terminated.
To add a port triggering service:
Make sure that you enable port triggering so that the service that you add will be used.
