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 
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 ISP assigned, which typically changes.
