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.
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.
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).
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).
Every group of ports must be set apart with ",". For example,
2000-2038, 2050-2051, 2085. 3010-3030.
