You've used Tailscale tunnels to establish secure connections between your devices.
Now get ready for Tailscale Funnels!
Funnels use Tailscale *magic* to make services on Tailscale nodes available outside of your tailnet (that is, accessible to the Internet) in a secure and controlled way. Kind of like if you stuck your own reverse proxy in front of it, but without having to manage another Linux instance.
I think I'm going to have fun with this!
