Private Networks: How Tailscale Works

Tailscale is a free open source version of the open-source version of Tailscale. It uses WireGuard, which creates a set of extremely lightweight encrypted tunnels between your computer, VM, or container, and any other nodes in your network. WireGuard creates a “hub and spoke” architecture, where each client device (say, your laptop) connects to a central “concentrator” or VPN gateway. In a hub-and-spoke, you just have one central hub node and 9 outliers (with “spokes” connecting them), which is much simpler.
