Virtual servers can be used for setting up public services on your LAN, such as DNS,
Email and FTP. A virtual server is defined as a service port, and all requests from Internet
to this service port will be redirected to the computer specified by the server IP. Any PC
that was configured as a virtual server must have a static or a reserved IP address
because its IP address may change when using the DHCP function.
