I would phrase that as what Tailscale does that is more convenient than wg. If you “barely know what a subnet is” go for it. wg is easy as pie though, and just don’t maintain 90 tunnels… You don’t need a full mesh. An extra hop or two, especially within a lan, won’t hurt.

I would recommend WireGuard as well, I primarily use it with Tailscale as backup. WG is straightforward to set up, and with LLM the knowledge gap is now nothing if you have trouble with it
