Tailscale

Instead of traditional vpn setup with gateways, etc., Tailscale connects directly to each machine with a direct wireguard tunnel. Technically creates its a mesh network, since there is both the unifying network that taliscale creates, tailscale also directly connects to each machine (mesh)

First connection attempt might be a little slow in order for it to establish first connection/key exchange.

Uses a Tailscale Coordination Server to manage keys, keep track of IP addresses, etc.
