Application Example: Making 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 will always give your web server an IP
address of 192.168.1.33.
