I have a question! Just a brief one cause I’m a little paranoid. I set Pi-hole up recently, using Pi-deploy on an old Android phone (not old old, a moto phone from 2020). Everything is running smoothly, I have it acting as a DHCP server and all devices in the house seem unhindered. The most configs I’ve been doing was whitelisting certain sites so emails function properly.
However, I was looking through the settings and the DNS server (which, according to the Pi-Deploy log, uses Unbound), is set to “permit all origins”. Which is in the risky category. So I wanted to ask if I can safely turn the option to “local requests only”. The IP I use is 192.168.1.xxx for everything (one piece of tech though is apparently running 10.0.0.1 or something, but it hasn’t been accessed recently), even the phone the server is running on I set to a static IP of 192.168.1.xxx. From what I found online, it should be safe for me to switch it to local only. But I heard I could potentially break the internet and wanted to get a second opinion here.
I also have a De-bug token here to look over: https://tricorder.pi-hole.net/PfQJow7X/
And for further context, this is the Pi-Deploy application I found for converting an android into a Pi-Hole server: GitHub - DesktopECHO/Pi-hole-for-Android: Pi-hole/Unbound Raspbian APK Installer for Android 5.0+ devices (requires root)
