I’ve moved your post to the #support:port-forwarding-help category of the forum. Posts in this category require some extra information to help diagnose your issue. Could you please provides the following:

Networking Gear & Setup Details

  1. Who is your internet service provider?

  2. Does your network have any VPNs, proxy servers, or enterprise-grade security?

  1. ISP: AT&T
  2. No VPNs, proxy servers, or enterprise-grade security.

@harsheel_dbs, what model of AT&T gateway do you have? As you have two routers in your network, you will need to create two port forwarding rules:

  1. From the AT&T gateway to the IP address of the RAX50 router using the port number found in Settings → Roon ARC

  2. From the RAX50 router to the IP address of the computer you use for your Roon Core, using the port number found in Settings → Roon ARC.

My AT&T Gateway is an Arris BGW210-700

There are a number of articles in the Community on how to configure the BGW210 for ARC using port forwarding, here are links to two of them:

Are you able to use your Admin pages on the 210 and RAX50 to create port forwarding rules on each?


fantastic, thank you!

Yes I should be able to get into the admin settings for both routers, I will follow the instructions you have posted and go from there.


I have configured both routers as your have instructed and now Roon ARC works. Thank you!


Glad to hear @harsheel_dbs and enjoy. Thank you @Robert_F for providing links to the relevant threads.
