I use tailscale, but there are other like this. One of them is called zerotier.

just use wireguard lol
Tailscale does use wireguard. Zerotier does something similar but it's tech is a slightly implementation and it's really meant for a lot of different devices.
I’m testing headscale
I think eventually I'll do that, and put all my traffic through that. Before I had fiber I was running my traffic, via openwrt, through separate vlans; mainly to isolate all this iot crap in our applications and toys.
Tailscale of course thanks to wireguard changed the whole self hosting game.
