2-4-2 Virtual Server
Configure the Broadband Router as a virtual server to allow the
Router to watch outgoing data for specific port numbers. The IP
address of the computer that sends the matching data is remembered
by the Router, so that when the requested data returns through the
Router, the data is pulled back to the proper computer by way of IP
address and port mapping rules such as the Web or FTP at the local
site via public IP addresses can be automatically redirected to local
servers configured with private IP addresses. In other words,
depending on the requested service (TCP/UDP port number), the
Broadband Router redirects the external service request to the
appropriate server.
