Virtual Server
If you configure the Barricade Plus as a virtual server, remote users
accessing services such as Web or FTP at your local site via public
IP addresses can be automatically redirected to local servers
configured with private IP addresses. In other words, depending
on the requested service (TCP/UDP port number), the Barricade
Plus redirects the external service request to the appropriate server
(located at another internal IP address).
The WAN interface must have a fixed IP address to utilize this
function. For example, if you set Type/Public Port to TCP/80
(HTTP or Web) and the Private IP/Port to 192.168.2.2/80, then all
HTTP request from outside users will be transferred to 192.168.2.2.
Therefore, by just entering the IP Address provided by the ISP,
Internet users can access the service they need at the local address
to which you redirect them.
