I haven’t installed it direct on my router. I used to have it running in a container on my little proxmox server (aka old PC repurposed). I really liked the interface.

Then I was practically gifted a really nice Asus router. I flashed merlin-wrt to it and read some guide on how to install a different ad blocker. It’s really good whatever it is. I haven’t had to touch it in months, and I never see an ad.
