Hello, I’m a nerd in this PI-Hole and routers with third-party firmware DD-WRT for example.
I share some advanced settings that I’ve tried, I know there are issues in this regard but they are very general and are spread throughout the forum. I hope and it will be helpful
I use a cisco e900 router with DD-WRT v3.0-r39137M mega (10/03/19) and an Orange Pi One with ARMbian Strech.
IP Router 10.0.0.1
IP Pi-Hole 10.0.0.141
server=10.0.0.141 cache-size=2048 log-async=5 #strict-order dhcp-option = 6,10.0.0.141
Configurations in my Pi-Hole
And this is the result in my Pi-Hole
I have also used Tomato Firmware and OpenWrt.
These are the configurations
These settings are when you use your router’s DHCP server and NOT your Pi-Hole server.
If someone has a different configuration; I would really appreciate it if you published it in this topic
