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