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 the Internet to this service
port will be redirected to the computer specified by the server IP. Any PC that was used for a
virtual server must have a static or reserved IP Address because its IP Address may change
when using the DHCP function.
