VIRTUAL SERVER SETTINGS (PORT FORWARDING)
Virtual Server (sometimes referred to as Port Forwarding) is the act of forwarding
traffic from one network node to another based on received protocol port number.
This technique can allow an external user to reach a port on a private IP address
(inside a LAN) from the outside through a NATenabled router. (Maximum 32 entries
are allowed.)
