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 router always gives your web server an IP address of 192.168.1.33.
2. In the Port Forwarding/Port Triggering screen, configure the router to forward the HTTP
service to the local address of your web server at 192.168.1.33.
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 router.
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 ISP assigned, which typically changes.

How the 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 router.
• Destination port number. 80, which is the standard port number for a web server
process.
2. Your router receives the message and finds your port forwarding rule for incoming port 80
traffic.
3. The router changes the destination in the message to IP address 192.168.1.123 and sends
the message to that computer.
4. Your web server at IP address 192.168.1.123 receives the request and sends a reply
message to your router.
