Advanced Settings - Virtual Server
The Virtual Server portion is designed to allow traffic from the WAN side that
is destined for a particular port to be specifically directed to the desired
machine/server on the LAN side of the router. In other words, depending on
the requested service (TCP/UDP port number), the Wireless Barricade Turbo
redirects the external service request to the appropriate server (located at
another internal IP address).
