Static Port Setting (Port Forwarding)

Port Forwarding redirects any incoming Internet request on the Public IP, based on its
TCP/UDP Port number to another computer in the Private IP. Hence, when a user from
WAN sends a request to your network, Compex CGX3224 (based on the Port–
Forwarding configurations) will forward these requests to the assigned PC.
When your ISP assign you with only one fixed Public IP address, and you want to
define the various servers (such as, FTP, HTTP, Net meeting, 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.
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.
