Advanced Setup

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.
