I have been frustrated with my network provider's use of CGNAT (T-Mobile Home Internet) and not allowing me to use ARC while I'm away. I knew there was this thing called Tailscale that could help me with that, but it seemed too complicated to set up and understand.

It turns out that they have an app for AppleTV, and it is super easy to get it up and running. I can finally use ARC in my daily commute to work! Happy times.
