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, as explained in “Using Address Reservation” on page 4-5. In this example, your router will always give your Web server an IP address of 192.168.1.33.

2.2. In the Port Forwarding screen, configure the router to 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.

3.(Optional) Register a host name with a Dynamic DNS service, and configure your router to use the name as described in ““Configuring Dynamic DNS” on page 5-1.

To access your Web server from the Internet, a remote user must know the IP address that has been assigned by your ISP. 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.
