Ah, perfect. The Mikrotiks weren't as straightforward earlier but maybe it's easier now. Glad to know it works on EdgeOS. Did you just use this? https://github.com/jamesog/tailscale-edgeos

On RouterOS you just need hardware that supports containers, then you can just run the offical tailscale image.

Otherwise there's native ZeroTier and WireGuard, but no Tailscale.
