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.
On the Port Forwarding/Port Triggering page, 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 on the
Dynamic DNS page of the modem router.
For more information, see
68.
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.
