My only real missing feature with my tailnet right now is the ability to somehow bridge mDNS / Bonjour.
I know those the multicast layer2 services and I can’t really run any magic reapeater on my WiFi hotspot either but it’s LITERALLY the last missing piece to have a unified virtual network of my things that works just as if I had them all home on my WiFi.
(Mainly needing it because Apple dev tools / Xcode etc. all rely on it and won’t let me simply say “connect to the device with this IP” - no idea where that feature went.. it used to be a thing).
