I enabled unbound in forwarding mode, and it will forward to an upstream DNS server. That works, but it is not forwarding hostnames. I only see my opnsense ip in the forwarder even though I have enabled register hostnames in unbound. Any idea why it is failing to pass hostnames? I have set hostname in DHCP for each host but it is not passing them.
Hello,
Maybe you should disable:
Never forward non-FQDNs and Never forward reverse lookups for private IP ranges
You can find these settings under Pi-Hole -> Settings -> DNS -> Advanced DNS settings
