since a little while i’m using 3 piholes in my home network.
1 running on a linux VM and 2 as Docker containers.
The VM is my primary internal DNS and one container is backup. The third pihole is for the kids and guests which uses OpenDNS as it’s upstream Servers and i can filter-out “dirty-stuff” with the OpenDNS filters.
So all 3 piholes work perfectly, except the 3rd one which forwards to OpenDNS.
I use the conditional forwarding to forward to my router and this works perfectly on the first 2 piholes. these both use my router as Upstream DNS too.
But if i use it one the pihole with OpenDNS, the conditional forwarding resolves no hostnames.
Is this “as expected” and do i need my router as Upstream DNS for it to work??
Thanks for the info!!
