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. • To add an entry to the list: Enter the following information, and then click Add to List.
