Hi @lenbell3,

Welcome to this forum.

I don’t know the AT&T router myself, but when i look at your image of the Firewall status i think i see your public IP there.

I watched below youtube video and there the personen clicked first on his computer (in your case your roon core with IP 192.168.1.70). In the video he created also a rule for UDP protocol, that’s not necessary for Roon ARC.

Did you do that also, first select you Roon Core pc?

How to Port forward AT&T Router

I also checked this site where is explained how to create a port forwarding rule.

Hope it helps.

Kind regards,

Maarten.

Thanks, TCP protocol was set up but not UDP which roon arc doesnt require… but it looks like UDP is required by the ATT router… once i set up UDP it work… issue resolved thanks
