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 section). Every group of ports must be apart with ",". For example, 2000-2038, 2050-2051, 2085, 3010-3030.

¾Incoming Protocol - This displays the protocol used for Incoming Ports Range, either TCP or UDP, or ALL (all protocols supported by the router).

Once configured, the operation for Port Triggering will proceed as follows:

Step 1: A local host makes an outgoing connection using a destination port number defined in the Trigger Port field.

Step 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.

Step 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.

To add/modify a port triggering entry:

Step 1: Click Add New…/Modify shown in Figure 4-25,you will see a new screen shown in Figure 4-26.

Step 2: Select the application you want from the “Common Applications”, then the Trigger port and Incoming ports will be added to the corresponding field automatically, you only need to configure the Trigger protocol and Incoming Protocol for the entry; If the “Common Applications” does not contain the applications that you want, please configure these options manually.
