3.4.2 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. (See
Glossary for an explanation on Port number)
