- 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).
