Same here. Wireguard.

Just did a quick Google… There are some resources and tutorials online of people doing exactly that. Take a look!

https://www.google.com/search?q=setup pihole on octopi

Only thing you might need to change is the configuration for which port the pi-hole web server (UI) will be running on. Because octoprint already uses Port 80 by default, you might have to assign another port for the pi-hole service. (I believe it also defaults to 80. That would crash because it can't bind to the same port). That should be a pretty simple config change though.

I had it setup using docker at the time. Both pihole and octoprint as individual containers…

But I assume you should be able to just install and run the package locally on the octopi distro.

Out of the box, pihole has a few block lists already set up. Those are pretty good already.

To add more, you can find some good block list collections online. No need to add them all. Pick a good handful, depending on the category of stuff you want to block. Here are some helpful links:

… Once you got a few block lists set up, you'll probably want to whitelist some things specifically, that are otherwise caught up in the filter. This is a super helpful resource for that:

Sure! If you've got that pi on all the time. I previously did that and it worked well. My current setup is multiple pi's though, cause the octo pi is switched off with the printer now…
