4.10.2 Port Triggering

Choose menu "Forwarding → Port Triggering", and then you can view and add port triggering
in the screen as shown in Figure 4-41. 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.
Once the Router is configured, the 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.
