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 (See Glossary for an
explanation on Port number).
