Virtual Server
If you configure the Barricade 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 redirects the external service request to the
appropriate internal server and port.
The WAN interface should have a fixed IP address to properly utilize this
function. For example, if you set Type/Public Port to TCP/80 (HTTP or
web) and the Private IP/Port to 192.168.2.2/8080, then all HTTP requests
from outside users will be transferred to port 8080 on 192.168.2.2.
Therefore, by just entering the IP Address provided by the ISP, Internet
users can access the service you provide at the internal address and port to
which the Barricade redirects them.
Some of the more common TCP service ports include:
HTTP: 80, FTP: 21, Telnet: 23 and POP3: 110.
