Tailscale version iOS 1.30.2
Your operating system & version iOS 16
I have Tailscale on my iPhone and use it’s VPN feature to ad block all ads while on cellular away from home.
Using the same Tailscale IP address, and using Termius I cannot get to the Pi Hole while away from home.
I use the exact same settings as while on my home network except I use the IP address from my Tailscale admin page.
I have done some Googling and see that it says to set it to accept all connections in the DNS page of settings on the Pi Hole.
