I love PiHole.

I run my PiHole on a small cloud VM that I use for several projects, but put it behind a VPN that's configured to only forward DNS lookups, then VPN into it from my phone. So many advantages behind this setup.

- Since only DNS lookups are tunneled, I don't have to worry about tunneling ALL my traffic and paying egress fees

- Blocks ads in ALL apps, not just my browser

- If it's acting up, I can just disconnect from the VPN to disable PiHoling

- Don't have to expose my home IP address and open a port for the world to start banging on
