I present an alternative way to use Pi-hole outside the home network by leveraging Encrypted DNS (aka DNS-over-TLS and DNS-over-HTTPS) instead of the usual VPN.
it’s also dead simple with netbird few clicks in the gui to setup a subnet router or join the dns box to netbird, then add it as the dns for all or whatever subdomains you want.
Tailscale has an technical article on this if you are starting from scratch.
If you can’t install tailscale on the pi-hole directly, you can also use a subnet router and a /32 with just that address to expose it to tailscale.
Came here to say this. Now I just need to upvote.
