N750 Wireless Dual Band Gigabit Router WNDR4300

• More than one local computer needs port forwarding for the same application (but not

simultaneously).

• An application needs to open incoming ports that are dif

ferent from the outgoing port.

When port triggering is enabled, the router monitors outbound traffic looking for a specified

outbound “trigger” port. When the router detects outbound traf

fic on that port, it remembers

the IP address of the local computer that sent the data. The router then temporarily opens the

specified incoming port or ports, and forwards incoming traffic on the triggered ports to the

triggering computer.

Port forwarding creates a static mapping of a port number or range to a single local

computer

. Port triggering can dynamically open 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 106.

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:

1. Select Advanced >

Advanced Setup > Port Forwarding/Port Triggering.

2. Select the Port T

riggering 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.
