Virtual Server
If you configure the Barricade Router 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 Router redirects the external service request to the
appropriate server (located at another internal IP address).
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
requests from outside users will be transferred to 192.168.2.2 on
port 80. 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.
The more common TCP service ports include:
HTTP: 80, FTP: 21, Telnet: 23, and POP3: 110.
