4.4.2.5 Virtual Server
Virtual server is a feature similar to port forwarding. You open ports in your
router to allow traffic from the internet to enter your LAN with the difference
that ports can be different on the WAN and LAN side.

Note:
Virtual server specifies only one port and not range of ports.
