Looks like you have Multiple Nats. See here to read up on it:

If the MultipleNatFound issue is caused by your ISP (CG-NAT) and you can’t get them to resolve the issue - at least at an acceptable cost, you can use Tailscale (and many other VPN solutions) to avoid the need to set up port forwarding at all.

The use of Tailscale for this purpose is supported by Roon and a description of its use is available in the Roon Help Centre at:

Hi @Acen_Grigorov,
Thanks for writing in to let us know about this issue. Like the other users said this is a problem from your ISP using CG-NAT. There are a few options to fix this depending on your exact situation. The article linked by @bearFNF goes into those troubleshooting steps.
