Can't find UPnP or NAT-PMP in ATT router

Support ARC: Port Forwarding Help
21

Hi @John_Dickerson,

I’m reviewing our conversation and the comments from other users, as automated account diagnostics indicate that the timeout is persisting.

Forgive me for taking us back a step, but do you have a second router in this setup, by chance? If so, then you’ll need to set the same port forwarding rule in both routers for the Core to see the external IP here.

With NordVPN disabled, follow these steps to disable IPv6 on the Windows as a precaution:
IPv6: How To Disable

  1. Use the shortcut, Windows Key + X to open the Control Panel.
  2. Open Network and Internet.
  3. Open Network and Sharing Center.
  4. Click Change Adapter Settings.
  5. Right-click your connection and go to Properties.
  6. Uncheck the box next to Internet Protocol Version 6 (TCP/IPv6) to disable it.

Once that’s done, please update to the latest version of Roon/ARC (released today, notes here) and restart your network hardware. I’m hoping the port forwarding will succeed after these steps, and please accept my apologies that we’ve been unable to resolve this more promptly.

We’ll be standing by for your response.
