I have, but I've not been able to VNC over them. I've made sure the FW rules let tailscale do anything and have even tried turning both firewalls off entirely but at least for TightVNC it doesn't like it, nor RDP (RDP enabled in System settings).

But this does give me hope that it can be done in the first place, I just have some setting goofed up somewhere. I will restart my tailscale stuff now that I know someone out there has done it.

Thanks!
