5. Port Trigger
Some applications require multiple connections, like Internet games, video conferencing,
Internet telephoning and so on. Port Triggering is used for some of these applications that
cannot work with a pure NAT Router.
Once configured, operation is as follows:
• A local host makes an outgoing connection to an external host using a destination port
number defined in the Trigger Port field.
• 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.
• When necessary, the external host will be able to connect to the local host using one of
the ports defined in the Open Port field
Rules
• Trigger Port - The port for outgoing traffic. An outgoing connection using this port
will trigger this rule.
• Trigger Protocol - The protocol used for Trigger Ports, either TCP, UDP, or All (all
protocols supported by the Router).
• Open Port - 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
which triggered this rule. You can input at most 5 groups of ports (or port sections).
Every group of ports must be separated with ",", for example, 2000-2038, 2046, 2050-
2051, 2085, 3010-3030.
