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 configure your modem
router to use the name.
To access your web server from the Internet, a remote user has to know the IP address
that your ISP assigned. However, if you use a Dynamic DNS service, the remote user can
reach your server by a user-friendly Internet name, such as mynetgear.dyndns.org.
