8.3. Port Forwarding (Virtual Server)
Use the Port Forwarding (Virtual Server) function when you want different servers/clients in
your LAN to handle different service/Internet application type (e.g. Email, FTP, Web server
etc.) from the Internet. Computers use numbers called port numbers to recognize a
particular service/Internet application type. The Virtual Server allows you to re-direct a
particular service port number (from the Internet/WAN Port) to a particular LAN private IP
address and its service port number.
