I ordered a Raspberry Pi 5 so I have a Pi 3 that’s about to be redundant. I haven’t used Pi-Hole so I was thinking it’d be good for that but I’m curious if there’s any downsides for users. Are sites blocked if you dont whitelist them? That sort of thing.
Basically, I’m not worried about me having issues but I’m worried about a maintenance headache if friends and family can’t access things.
Just make sure you have port 53 and 80 open. I recently had some problems myself trying to get Pi-Hole up and running. I already had dnsmasq taking up port 53 for a wifi hotspot, which conflicts with Pi-Hole’s own DNS. Aside from that, hosting any websites can also conflict with Pi-Hole’s frontend.
If you aren’t using your Pi 3 for anything yet then I already assume this shouldn’t be a problem though.
Good luck and have fun setting up your Pi-Hole!
