Tailscale implementation with ARC to circumnavigate ISP CGNAT

Ok, I understand. That’s what I was wondering as it seemed like everything was installed correctly. I have Tailscale installed on my NAS, I just have also added my MacBook and iPhone as extra machines. So, for clarity, I should be able to get ARC connected to my ROCK when I’m home on my local network irrespective of my internet provider (Starlink) and Tailscale? I know I was unable to do this which is why I started exploring options and discovered this thread.
