Not sure what you mean here, but I am quite sure I need to set the network mode like that to route the network through the VPN.

I prefer docker because I can plop it in elsewhere if needed.

How does one do this? Is there an article I could read up on?

I wanted to do it with pure wireguard. I like the headscale idea though. Might give that a shot.

Thanks for the NUT idea. I’ll look into it and reply back again when I’m next awake. Thank you.

I was worried about the powering back, unfortunate. Will look for ups’ that can help with this. If anyone knows of this please let me know.

Yepyep! That I do know about. Should’ve clarified I meant power back on IFF it’s no longer dependent on the ups to continue functioning.
