Firewall – 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.

Local IP: This is the LAN client/host IP address that the Public Port number packet will be
