First, thank you all for bring such a great project to the world!
So, I follow method 2 of this guide: How do I configure my devices to use Pi-hole as their DNS server?
My router is running DDWRT firmware so I just need to do exactly every step
After that, my whole home network has adblocking: my iphone, my wife's android, my android TV, webOS TV,...
Everything go well except for 3 devices:
- OrangePiOne and TX3Mini, both of them are running Armbian Buster
- Mi Router 4A 100M running OpenWRT 19.07.3 (its WAN port plug into LAN port of the main router)
They has same problem: has LAN access (ping, ssh,...) but not internet access. I check their /etc/resolve.conf, it contains only ip of Pi Hole.
I figure out that if I change /etc/resolve.conf to 1.1.1.1 or 8.8.8.8, they can access internet normally
Another scenario
I also tried another method, which is using Pi Hole as DHCP server (after completely disable DHCP, dnsmasq on my router). This time, these 3 devices above didn't even get IP assignment at all (other devices - ios, android, webos tv,... of course still working normally)
English is not my first language, sorry for any mistake
