Set Up Port Triggering
Port triggering is a dynamic extension of port forwarding that is useful in these cases:
More than one local computer needs port forwarding for the same application (but not 
simultaneously).
An application must open incoming ports that are different 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 traffic 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, enable Universal Plug and Play (UPnP). See 
138.
To set up port triggering, you must know which inbound ports the application needs. Also, you 
must know the number of the outbound port that triggers the opening of the inbound ports. 
You can usually find this information by contacting the publisher of the application or user 
groups or newsgroups.
To set up port triggering:
1.
Log in to the router.
