OpenWrt + PiHole help!

Help Community Help

I am currently using OpenWrt v6.6.119. I have tried a number of things to attempt to get this to work, but my pihole web UI is entirely dead. Zero traffic.

What I have tried:

  • This guide - same as step #2 in How do I configure my devices to use Pi-hole as their DNS server?

  • Step #1 in the above guide

  • Step #3 in the above guide

  • Tried all three interface settings (Respond only…, Bind only…, Permit all origins)

  • Network > Interfaces > LAN > DHCP Server > Advanced Settings > DHCP Options

Enter pi-hole IP here after "6, " without quotes. E.g. "6,192.168.2.1" without quotes, where 192.168.2.1 is the IP address of your pi-hole.

Note: I had HTTPS DNS proxy enabled for the first four options I tried. I am now going to go back through right now and try them again with DNS over HTTPS disabled to see if that was causing issues.

I have made sure to revert changes before attempting a new method in LuCl, but no dice. Pls help!

Update:

I forgot to disable WLAN on the Pi. That is now fixed and I am able to manually point devices to the Pi DNS resolver. At the moment, it looks like the DNS server assigned automatically is still 192.168.1.1. I have the DHSCP lease time set to 5 minutes, plus manually deleting the lease, so changes are being pushed basically immediately.

Continuing to fiddle around and I’m making progress. I just added an entirely fresh never-connected device to the network and it automatically was assigned the Pi’s DNS IP. I guess I just need to figure out how to clear the DNS assignment on this device to get it to automatically be assigned the Pi’s IP.

So I guess I pretty much solved that for myself lol, that’s that hopefully.
