9.2Defining 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 WP11A+ (based on the Port–Forwarding configurations) will forward these requests to the assigned PC.

9.2.1When 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.

9.3Configuring Port–Forwarding virtual server with Compex WP11A+
