I have been using Tailscale VPN with my servers for about 6 months now and I would recommend it to anyone.
I'm running it on both of my Proxmox machines, my laptop, a raspberry pi, and my Android phone. It makes it super easy and secure to access my local services while away from my house.
Very simple set up, minimal initial configuration, and versatile.
There are apps for Linux, Windows, Mac, Android, and iOS.
Is anyone else currently using Tailscale? I'd like to hear what you all think.
