Description of Issue


That is the error I get and I’m assuming but I’m not sure that I need to create a pass through on my modem router from AT&T. I’m not sure what to input into the fields. Can someone please assist. The model number of the modem router is BGW320

You need to set-up port forwarding through the NAT/Gaming menu I think. Wow that looks a bit tedious / complicated for a single port but I see why AT&T decided to do it this way.

I don’t have one of these routers so won’t try to fumble through it. You can try and find other AT&T users here and follow their instructions Port Forwarding Resources - Roon Labs Community

Hey @Garry_Underwood,

Ben with the support team here, I wanted to check in on this thread to see if you’re still having issues getting arc up and running.

Here is a step by step on getting port forwarding setup on your specific router:

To open a port for user-defined applications:

  1. Go to your gateway settings.
  2. Select the Firewall tab.
  3. Enter the Device Access Code found on the side of your gateway.
  4. Select NAT/Gaming.
  5. 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.
  6. From the Service drop-down, select the application for port forwarding. If your application isn’t in the list, or you are setting up port forwarding for a device:
  • Select Custom Services.
  • Enter the name for the application or device in Service Name.
  • Enter the port(s) you wish to open for Global Port Range.

It is recommended to create a separate service entry for each port as opposed to using a port range. In this case the port number should be the same in the Global Port Range fields.

  • In Base Host Port, enter the port number used for the first Global Port Range section.
  • Select the appropriate Protocol from the drop-down for the application or device you are adding.
  • Select Add. Repeat as needed for additional applications and devices.
  • When all applications or devices have been added, select Return to NAT/Gaming. Your new applications or devices will display in the Applications list.
  1. From the Needed by Device drop-down, select the device name or IP address of the device to open the port.
  2. Select Add.
  3. When your selections display in Hosted Applications, select Save.
