Just installed the Tailscale client on my desktop machine, my laptop, and iPad. Logged in with GitHub on all three devices. The desktop machine was assigned a fixed IP and I can just type in an http URL with the ip address and the browser connects from any device.

One nice thing about it is it does the right thing if the client is in my house (connect via the LAN) or if I am out or about. Early on I had the tablet disconnect, but I found out that I just had to restart the Tailscale client and it was back up right away.
