Verizon Wireless G3100 - Port Triggering

PORT TRIGGERING
./ 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 gaming server is accessed using UDP protocol on
port 2222. The gaming server then responds by connecting the
user using UDP on port 3333, when a gaming 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 Home Router IP, and the connection
is not sent back to the host since it is not part of a session.
To resolve the conflict, a port triggering entry must be defined,
which allows inbound trac on UDP port 3333 only after a network
host generated trac to UDP port 2222. This results in your
Fios Home Router accepting the inbound trac from the gaming
server and sending it back to the network host which originated
the outgoing trac to UDP port 2222.
