This Section
This FAQ has three major sections:
Section 1 - General Information
Section 2 - Opening Ports Using Predefined Settings for Popular Applications on the Westell 2100/2200
Section 3 - Manually Opening Ports Using Custom Settings

Section 1 - General Overview

The Westell 2100/2200 modems are actually routers and by default blocks ports so some popular games and applications may not work correctly. Changes must be made to the Westell to open certain ports. The screenshots and procedures below are for Westell 2100/2200 modems only. The Westell 6100 has the same capabilities but a different menu structure. Important note: Opening ports exposes you computer directly to the Internet. A firewall of some type is highly recommended.

Many popular applications and games are preconfigured in the firmware and simply require you to enable the service as shown in Section 2. Some newer games or applications are not available and must be configured manually as shown in Section 3. The specific port and protocol information required to set up a custom manual service can be obtained from the vendor or you can click here for a partial list of ports for some of the more popular applications.

An alternative way to enable proper gaming connection is IP Passthrough. More details are available Here.

Step 2
Click on Expert Mode from the menu and confirm that you want to enter Expert Mode. Important Information: You will not be able to access Expert Mode if you are using Internet Explorer 7.

Step 4
The port settings and protocols for many popular applications are already preconfigured. Use the Service Name pull down to highlight and select the application you desire and then click Enable.

Step 5
A pop-up screen will appear with a pull down of all the computers connected to the Westell. Select the correct computer and click Done

Step 6
The NAT screen will show a confirmation listing the service you selected. You can click on Details for specific information about port and protocol settings for each service.

Step 7
Repeat Steps 4 through 6 for every game, service or application you wish to run. If your application is not available in the pull down, you want to manually open ports, or you want to configure a custom service proceed to Step 8.

Section 3 - Manually Opening Ports Using Custom Settings

Step 8
To set up a custom port forwarding configuration click Define Custom Service.

Step 9
Select Port Forwarding Range of Ports and click Next.

Step 10

Example: Service XYZ requires ports 3000-3010. You will enter "1-10" in the Global Port Range and "3000" in the Base Port field.

Step 11
Verify the information for this application is correct and click Close.

Step 12
The custom service you created is now available in the Service Name pull down. Select the new custom service and click Enable. Repeat Steps 8 through 12 for every custom service you require.

Feedback received on this FAQ entry:
  • Hi, I found your page while trying to set up port forwarding on a Belkin router. I am scratching my head at the part about global port range and base host port. Perhaps if you update this page you may add a little detail about this concept. I am trying to allow a connection on port 5000. What would I enter. Base = 5000 and range 0-0 ? Otherwise your instructions are straight forward.. Regards
