PORT TRIGGERING
Port triggering can be described as dynamic port forwarding. By
setting port triggering rules, inbound traffic arrives at a specific
network host using ports that are different than those used for
outbound traffic. The outbound traffic triggers the ports where the
inbound traffic 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 traffic by default.
• Server replies to your Verizon 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 traffic on UDP port 3333 only after a network
host generated traffic to UDP port 2222. This results in your
Verizon Router accepting the inbound traffic from the gaming
server and sending it back to the network host which originated the
outgoing traffic to UDP port 2222.
To configure port triggering:
1.
From the Advanced
Advanced menu, select Security & Firewall
