To open a port for user-defined applications:
- Go to your gateway settings.
- Select Settings > Firewall > Applications, Pinholes and DMZ. If you receive a warning message, visit the AT&T Port Forwarding tool to enable port forwarding on your account. Then, you can continue with the steps in this solution.
- Under Select a Computer, select the device name or IP address for the device you wish to open a port for. If the IP address or device name isn’t listed, enter it in the Enter IP Address field and select Choose.
- Under Edit firewall settings for this computer, select the Allow individual application(s) button.
- Select the application from the list, and select Add to move it to Hosted Applications.
If your application isn't in the list:
- Select Add a new user-defined application.
- In Application Profile Name, enter the name for the application or device.
- Select the appropriate Protocol button.
- Enter the port(s) you wish to open for From and To.
It's recommended to create a separate user-defined application/device entry for each port as opposed to using a port range. In this case the port number should be the same in the From and To fields.
- Leave the Protocol Timeout and Map to Host Port fields blank unless you want to define manually.
- From the Application Type drop-down, select the type of application you're setting up port forwarding for. If your device or application isn't listed, leave it set at “-“ default.
- Select Add to List. Repeat as needed.
- When all applications have been added, select Back. Your new applications will display in the Applications list.
- When your selections display in Hosted Applications, select Done.
Congratulations, you’ve set up port forwarding for your gateway!
