Verizon ARC-XCI55AX User Manual page 81

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 Internet Gateway 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 Internet Gateway 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:
