When to use Port–Forwarding Virtual Server
When your ISP assign you with only one fixed Public IP address, and you
want to define the various servers (such as, FTP, HTTP, Netmeeting, Mail
server etc) to specific Private IP address in your LAN; hence, you can
choose to host the servers by using the Port-Forwarding Virtual server.
Example, suppose that you have a FTP Server with an IP address of
192.168.168.41. And your broadband ISP has assigned a Public IP address
of 203.120.12.100 to the gateway. To support a Web Server in your Private
Network, you need to define an NAT Static Port-based Entry to forward
TCP port 21 (used by FTP) to 192.168.168.41. Every http://203.120.12.100
requests will then be forwarded to the FTP Server.
