PORT FORWARDING
Port forwarding (sometimes referred to as tunneling) is the act of
forwarding a network port from one network node to another. This
technique can allow an external user to reach a port on a private IP
address (inside a LAN) from the outside through a NAT-enabled router.
(Maximum 32 entries are allowed.)
