Being a natural Internet firewall, this network router protects your network from being
accessed by outside users. When it needs to allow outside users to access internal
servers, e.g. Web server, FTP server, E-mail server or News server, this modem can act
as a virtual server. You can set up a local server with specific a port number that stands
for the service, e.g. Web (80), FTP (21), Telnet (23), SMTP (25), POP3 (110), When an
incoming access request to the router for a specified port is received, it will be
forwarded to the corresponding internal server.
For example, if you set the Service Port number 80 (Web) to be mapped to the IP
Address 192.168.1.2, then all the http requests from outside users will be forwarded to
the local server with IP address of 192.168.1.2. If the port is not listed as a predefined
application, you need to add it manually.
When you click Virtual Server, you get the following figure.
Enable: Enable or disable this Virtual Server port.
