4. Click Edit Service or Delete Service.

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 router always gives your web server an IP address of 192.168.1.33.

2. In the Port Forwarding/Port Triggering 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.

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.

Set Up 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.

When port triggering is enabled, the router monitors outbound traffic looking for a specified

outbound “trigger” port. When the router detects outbound traffic on that port, it remembers

the IP address of the local computer that sent the data. The router then temporarily opens the

specified incoming port or ports and forwards incoming traffic on the triggered ports to the

triggering computer.

Port forwarding creates a static mapping of a port number or range to a single local computer.

Port triggering can dynamically open ports to any computer that needs them and can close

the ports when they are no longer needed.
