I appreciate the explanation about the gold robot.

Thank you that is tremendously helpful! I expect this post will help others that come along.
So confirming for your setup, you do need Remote Access enabled to use 100.x while home on your local network on wifi as well (and of course while away on cellular).
That’s how it seems to be for me, so I think I’m set up correctly. I don’t believe I’ve opened any unusual ports or anything like that.
Thanks for the explanation. That part is clear, and I can access the server/Mac computer from my iPhone using the 100.x IP address. But if I’m on cellular I need to have Remote Access Settings enabled in order to connect.
Edit: Actually on Wifi too on the same local network I need remote access enabled if I’m using the 100.x IP addresses. Using the usual IP pre-Tailscale I don’t need remote access on wifi.
I cancelled AppleOne and reduced our Apple services to just Music and iCloud storage. Not sure that’s what Apple was going for.
