5.6.2 Port Triggering

Some applications require multiple connections, like Internet games, video conferencing, Internet calling and so on. These applications cannot work with a pure NAT router. Port Triggering is used for some of these applications that can work with an NAT router. You can set up Port Triggering on this page shown in figure 5-15:

Figure 5-15 Port Triggering

Once configured, 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.
