4.9.2 Port triggering
Go to Forwarding > Port Triggering in order to configure the Port Triggering parameters on
this menu, as shown in Figure 4-30.
Once configured, the operation is as follows:
To add a new rule, follow the steps below:
A local host makes an outgoing connection to an external host using a destination port
number defined in the Trigger Port field.
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.
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.
Click the Add New… button o the Port Triggering page. (Figure 4-31)
Select a common application from the Common Applications drop-down list, then the port
parameters will be automatically filled in the corresponding field. If the Common Applications
list does not have the application you want, enter the port parameters manually.
Select the protocol used for Trigger Port and Incoming Ports from the corresponding
pull-down list.
Click on Enable on the Status field.
Click the Save button to save the new rule.

triggered this rule. You can input at most 5 groups of ports (or port section). Every group
of ports must be separated by commas “,”. For example, 2000-2038, 2050-2051, 2085,
3010-3030.
