4.8.2 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 4-32:

Figure 4-32 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.

¾ Trigger Port - The port for outgoing traffic. An outgoing connection using this port will

"Trigger" this rule.

¾ Trigger Protocol - The protocol used for Trigger Ports, either TCP, UDP, or All (all

protocols supported by the router).

¾ Incoming Ports Range - The port or port range used by the remote system when it

responds to the outgoing request. A response using one of these ports will be forwarded to

the PC that triggered this rule. You can input at most 5 groups of ports (or port section).
