Learn more about port forwarding

Port forwarding is used to route incoming and outgoing data on your home network from a remote location.

Every device connected to the internet has an IP address divided into various ports that send and receive data. Your gateway routes this data to where it needs to go. When you set up port forwarding, you set up rules to tell the gateway to route data sent or received on a port to a specific IP address on your home network.

Most users won’t need to use port forwarding, but you might if you do any of the following:
  • Run a Sling box or other streaming media device
  • Host a web or gaming server
  • Access a home surveillance camera or device remotely
  • Use Remote Access or VPN to access a computer in the home
  • Host photo-sharing hard drives

Port forwarding should be used with caution because it may allow others to access devices in your home without your knowledge.

Set up port forwarding

To open a port for user-defined applications:
  1. Go to your gateway settings.
  2. 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.
  3. 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.
  4. Under Edit firewall settings for this computer, select the Allow individual application(s) button.
  5. 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. Edit firewall settings and filter applications
  6. When your selections display in Hosted Applications, select Done.

Congratulations, you’ve set up port forwarding for your gateway!
