3‐5‐1 Virtual Server
This function allows you to redirect a port on Internet IP address (on WAN port) to a
specified port of an IP address on local network, so you can setup an Internet service on the
computer on local network, without exposing it on Internet directly. You can also build
many sets of port redirection, to provide many different Internet services on different local
computers via a single Internet IP address.
