TailScale

NO. Just no. This aggressive know-it-all "zero-conf" beast trashed my delicate DNS and sent me down a three-day ipv6 nightmare... much of which was not tailscale's fault... but automatic everything is a pipe dream to avoid..

---

TailScale sits on top of WireGuard to make it more zero-conf. But it's provided as a free SaaS. So that is concerning that they will just monetize it some day. But let's try it.

Installation

Setup is dead simple.

Create an account
Start installing tailscale on each device

It really is that simple. Unfortunately, it DID NOT CONNECT from the Cleveland Clinic to home.

Troubleshooting

It works by taking over DNS via /etc/resolv.conf. I've already carefully done that with dnsmasq in a way that is apparently not compatible. Tailscale uses some "MagicDNS" bs... i think i need to turn it off... but I'm going back to wireguard for now, i don't need more troubles...
