Chapter 5 Web-based Interface Configuration for Compex SGX3226

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.

Follow the steps shown below to configure Static Port.

1.Go to NAT function at the Command Window. Select the type of Server you wish to configure as shown in the figure below:

2.Key in the Private IP Address.

3.Next, choose a transport protocol, either TCP or UDP, for the respective IP Address.
