Um. I already have like 100s of WG connection. Office to cloud, various servers all over connected to others, servers on many WG "subnets".
WG is the easiest VPN I've ever used. Dropped all these other crazy rigs (stunnel, ssh-tunnel, etc) cause WG always "just works" and is on every platform.
However, I've spent loads of time as network admin, planning IP-space for VPN layers, first time in 1997.
Try this: Go set up a Wireguard connection from your PC at home to one at work.
Then do the same thing with tailscale.
One will be a lot easier than the other. And that's only 2 computers...
