5.7.2 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 5-27:
Figure 5-27:
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.
