Virtual Server
Figure49
If you configure the BLW-04EM 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 BLW-04EM 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 192.168.1.2/80, then all HTTP requests from outside users
will be transferred to 192.168.1.2 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.
