roon arc with starlink router bypassed still not working

Hi @Zeki_Mustafa, We’re working on implementing a fix to a known nomenclature discrepancy between Starlink and RoonServer’s handling of IPv6. There’s a ticket in with the team to investigate a solution for this issue. Please see here for a temporary workaround: Starlink (ISP) with ARC: CG-NAT Requires VPN Workaround (See Staff Post)

Unfortunately I know of no VPN company that supports IPv4 port forwarding over IPv6. Do you know of one that will do this?

I have no idea, but the linked post is probably the latest info regarding the status of the address format issue because Connor posted it yesterday

I found Connor’s post that refers back to Peter Gallagher’s post. There is no fix yet.

I didn’t say there is a fix. He wrote “We’re working on implementing a fix to a known nomenclature discrepancy between Starlink and RoonServer’s handling of IPv6. There’s a ticket in with the team to investigate a solution for this issue”

This seems to answer your question,

IPv6 issues - update?

Maybe try the Tailscale VPN service, Roon recommends it for some network configurations for ARC, but not sure if this still works with Starlink. The below solution is about a year old:

Starlink compatibility for Roon ARC?

I got it working pretty easily on Starlink with Tailscale. Didn’t even need port forwarding. The key was running the ARC app’s initial setup while connected to my local network. Then I could turn wifi off on my phone, connect to Tailscale, and ARC worked. How well it works will depend on what kind of mood Starlink’s in. When I first tried it this afternoon, it worked really well. When I tested it a little just now, there were a decent number of pauses while playing a test track. So YMMV but it’s…

I’ve been using ProtonVPN with ARC over Starlink while Roon gets their IPv6 trip together.

Yes, that is what I meant. Thanks for your help in finding this.
