./ PORT TRIGGERING
Port triggering can be described as dynamic port forwarding. By
setting port triggering rules, inbound trac arrives at a specific
network host using ports that are dierent than those used for
outbound trac. The outbound trac triggers the ports where the
inbound trac is directed.
For example, a web server is accessed using UDP protocol on port
2222. The web server then responds by connecting the user using
UDP on port 3333, when a web session is initiated.
In this case, port triggering must be used since it conflicts with the
following default firewall settings:
• Firewall blocks inbound trac by default.
• Server replies to your Fios Router IP, and the connection is not
sent back to the host since it is not part of a session.
