Port forwarding creates a static mapping of a port number or range to a single local computer.
Port triggering dynamically opens ports to any computer on the LAN and closes the ports
when they are no longer needed.
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) according to the instructions
in Universal Plug and Play on page 102.
To set up port triggering, you need to know which inbound ports the application needs. Also,
you
need to know 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 newsgroups.
 To set up port triggering:
1. Select Advance
d > Advanced Setup > Port Forwarding/Port Triggering.
2. Select the Po
rt Triggering radio button.
3. Clear the Disable Port Triggering check box if it is selected.
Note: If the Disable Port Triggering check box is selecte
d 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.
