Port Triggering 

Once the Router is configured, the operation is as follows:   

1.  A local host makes an outgoing connection using a destination port number defined 

in the Trigger Port field.   

2.  The Router records this connection, opens the incoming port or ports associated 

with this entry in the Port Triggering table, and associates them with the local host.   

3. When necessary，  the external host will be able to connect to the local host using 

one of the ports defined in the Incoming Ports field.

Trigger Port - The port for outgoing traffic. An outgoing connection using this port 

will trigger this rule. 

¾

 

Trigger Protocol - The protocol used for Trigger Ports, either TCP, UDP, or All (all 

protocols supported by the Router). 

¾

 

Incoming Ports Range - The port or port range used by the remote system when it 

responds to the outgoing request. A response using one of these ports will be 

forwarded to the PC that triggered this rule. You can input at most 5 groups of ports 

(or port sections). Every group of ports must be set apart with ",". For example, 

2000-2038, 2050-2051, 2085, 3010-3030. 

¾

 

Incoming Protocol - The protocol used for Incoming Ports Range, either TCP or 

UDP, or ALL (all protocols supported by the Router).
