Virtual Server
Use the 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.
