Adding a Custom Rule

To define rule that does not appear in the Service list, you must first determine which port number

contacting the publisher of the application or user groups or newsgroups. When you have the port

number information, follow these steps:

1.

In the Port Forwarding screen, enter the name of the rule in the Add Custom Rules section of

the screen.

2.

In the

Starting Port

field, enter the beginning port number.

•

If the application uses only a single port, enter the same port number in the

Ending Port

field.

•

If the application uses a range of ports, enter the ending port number of the range in the

Ending Port

field.

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.
