Is it normal for Home Assistant to send DNS requests to its Default Gateway address even though local DNS Server addresses have been configured and are working?
Thanks but I don’t think that will help as invoking the ‘fallback: false’ option stops calls to CloudFlare and I think that those issues with CoreDNS have been fixed some time ago.
In my firewall logs I’m seeing DNS traffic going to my DNS servers (expected) and approximately once an hour I see a bunch of DNS request directed at port 53 of the Default Gateway address (unexpected).
I noticed the very same since a couple of month (can not recall when this started again, it was back to good for some time before after it got fixed).
Ended up by rerouting those DNS bursts going directly to the gateway’s port 53 to my internal DNS server by configuring the firewall at the gateway accordingly. Not really elegant though 
Thanks, good to know it’s not just me with some wonky settings…
Yep setup a port forward rule for any DNS requests directed at the Gateway Address to go to my DNS Servers.
Would be nice to know what is causing the hourly bursts to the gateway address…
