Port Triggering

Port triggering can be used for dynamic port forwarding configuration. By setting
port triggering rules, inbound traffic is allowed to arrive at a specific network host
using ports different than those used for the outbound traffic. The outbound traf-
fic triggers which ports inbound traffic is directed.
For example, a gaming server is accessed using
gaming server responds by connecting the user using
starting gaming sessions. In this case, port triggering must be used, since it con-
flicts with the following default firewall settings:
• The firewall blocks inbound traffic by default.
• The server replies to the Router's
the host, since it is not part of a session.
To resolve the conflict, a port triggering entry must be defined, which allows
inbound traffic on
port 2222. This results in accepting the inbound traffic from the gaming
UDP
server, and sending it back to the network host which originated the outgoing traf-
fic to port 2222.
