Defining Port-Forwarding Virtual Server
Port Forwarding redirects any incoming Public IP Internet request to another computer
on a Private IP based on its TCP/UDP Port number.
Hence, when a WAN user sends a request to your network, the Compex WP11B+
(based on the Port–Forwarding configurations) will forward these requests to the
assigned PC.
14.2.1
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; you can choose to host
the servers by using the port-Forwarding Virtual server.
For 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.
