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. On the Port Forwarding screen, configure the router t
o
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.
