How to Port Forward on AT&T U-verse
By Denise Sullivan
If you get your Internet service through AT&T U-verse and need to use an application or devices on your local network while away from home, you must first configure the port forwarding on your modem. This is typically required to use surveillance cameras, streaming media devices, VPNs or remote desktop access programs, Web servers and shared hard drives. Port forwarding instructs your modem to direct all data received on a specific port to the IP address of your choice, giving you access to the network without compromising its security.
Open the Web browser of your choice and type "http://homeportal/" to access the AT&T U-verse home page. Click on the "Settings" tab and select the "Broadband" link.
Look for your IP address under "Internet Details." If it begins with "10.x.x.x," you must use AT&T's port forwarding tool to modify your port assignments and automatically configure your modem. If your IP address starts with any other digits, you may continue with manually configuring your modem.
Select the "Firewall" subtab and click the link for "Applications, Pinholes and DMZ." You will see a list of computers and other devices connected to the network and their IP addresses. Select the computer that will be hosting the application or sharing files. You can also enter an IP address in the text box and press "Enter" to select a specific computer.
Click the radio button for "Allow individual applications" under "Edit firewall settings for this computer." Select your application from the list and click "Add." Click "Save" to save your port forwarding instructions.
Select "Add new user-defined application" if your application was not displayed in the list or you need to set up port forwarding for a device. Enter a new profile name and select the "TCP" or "UDP" protocol button, whichever applies to your application or device. Leave the fields for "Protocol Timeout" and "Map to Host Port" blank unless they are specifically needed for your application.
Enter the port range for forwarding in the "From" and "To" fields. Select the application type from the drop-down menu or leave it as "-" for device forwarding. Click "Add to List" to add the application. Repeat this step if you need to add another application or device. Click "Back" to return to the list of applications. Select your application or device and click "Add." Select "Save" to save your changes.
