N600 Wireless Dual Band Router WNDR3400v3
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 that needs them and can
close 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 90.
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 triggers 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 Advanced > Advanced Setup > Port Forwarding/Port Triggering.
2. Select the Port Triggering radio button to display the port triggering information.
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 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.
