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 “Address Reservation” on page 5-4 . In this example, your router
will always give your Web server an IP address of 192.168.1.33.
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 “Using a Dynamic DNS Service” on page 5-5 .
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.
Configuring Port Triggering
Port triggering is a dynamic extension of port forwarding that is useful in these cases:
•
More than one local computer needs port forwarding for the same application (but not
simultaneously).
• An application needs to open incoming ports that are different from the outgoing port.
