Application Example: Make a Local Web Server Public

If you host a web server on your local network, you can use port forwarding to allow web requests from anyone on the Internet to reach your web server.

To make a local web server public:

1.Assign your web server either a fixed IP address or a dynamic IP address using DHCP address reservation.

In this example, your modem router always gives your web server an IP address of 192.168.0.33.

2.In the Port Forwarding/Port Triggering screen, configure the modem router to forward the HTTP service to the local address of your web server at 192.168.0.33.

HTTP (port 80) is the standard protocol for web servers.

3.(Optional) Register a host name with a Dynamic DNS service, and specify that name in the Dynamic DNS screen of the modem router.

For more information, see Dynamic DNS on page 62.

Dynamic DNS makes it much easier to access a server from the Internet because you can type the name in the Internet browser. Otherwise, you must know the IP address that the Internet provider assigned, which typically changes.

How the Modem Router Implements the Port Forwarding Rule

The following sequence shows the effects of a port forwarding rule:

1.When you type the URL www.example.com in your browser, the browser sends a web page request message with the following destination information:

•Destination address. The IP address of www.example.com, which is the address of your modem router.

•Destination port number. 80, which is the standard port number for a web server process.

Specify Internet Port Settings
