ORWARDING

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.)
