Port Triggering
Port triggering allows the router to watch outgoing data for specified port
numbers. The IP address of the computer that sends the matching data is
remembered by the router, so that when the requested data returns through the
router, the data is transmitted to the proper computer by using IP address and port
mapping rules.
Some Internet applications or games use alternate ports to communicate between
the server and LAN host. When you want to use these applications, enter the
triggering (outgoing) port and alternate incoming port in the Port Triggering table.
Then the router will forward the incoming packets to the specified LAN host.
Add or edit entries as needed. Remember that the settings are not saved until you
click the Save button.
