5. In the Protocol list, select the protocol. If you are unsure, select TCP/UDP.

6. Specify the port settings:

• External Starting Port and External Ending Port. These are the starting number

and ending number for the public ports at the Internet interface. For single port

forwarding, number in the External Starting Port and External Ending Port fields can

be the same. The range is from 1 to 65534.

• Use the same port range for Internal port. This check box is selected by default. If

you want to use different ports, clear this check box and specify the internal ports.

• Internal Starting Port and Internal Ending Port. These are the starting number and

ending number for the ports of a computer on the router’s local area network (LAN).

These are private ports. The router calculates the internal ending port.

7. In the Internal IP Address field, enter the IP address of your local computer that will provide

this service.

8. Click Apply. The service appears in the list in the Port Forwarding/Port Triggering screen.

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. 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 as described in

Dynamic DNS on page 102. 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:
