New user to OPNsense here. I previously used homenetworkguy.com's beginner guide on setting up OPNsense. (https://homenetworkguy.com/how-to/beginners-guide-to-set-up-home-network-using-opnsense/#unbound-dns-general)
On top of those settings I have also UNTICKED " Allow DNS server list to be overridden by DHCP/PPP on WAN".
I don't have any sort of blocklists or whitelists enabled beyond the changes above. I've added 9.9.9.9 and alternatively also Cloudflare's as my "DNS over TLS" options to test it out but unfortunately with either option I have issues with Google ads being blocked automatically when my Phone for example uses Unbound's DNS server.
My local Windows PC shows the below results as well for nslookups:
C:\WINDOWS\system32>nslookup googleadservices.com
Server: OPNsense.localdomain
Address: 192.168.1.1
Name: googleadservices.com
Address: 0.0.0.0
On my Android phone, when I use the "Private DNS" option and use the very same 9.9.9.9 DNS server directly those ads work fine.
I typically use Zenarmor as well, but I've ruled this out being an issue since the issue above persists even when I put it into "reporting only" mode etc.
What am I missing here? If it helps I have attached 2 (shrunked) screenshots of the most relevant pages on OPNsense I could find. (Why is the attachment limit a TOTAL size of 256KB...., can't even post more than 2 screenshots at this rate)
