I have configured Cisco Umbrella VA to handle DNS resolution for some domains, and I’ve set up conditional forwarding on my Domain Controller (DC) to forward queries for example.com to Google DNS (8.8.8.8). . However, I'm encountering an issue where nayatel.com is still being resolved by Umbrella VA despite it being set as a conditional forwarder in the DC. Even after blocking traffic to 8.8.8.8 from the DC in the firewall, nayatel.com resolves correctly via Umbrella VA and I can see it in the Umbrella dashboard, while other domains (with same configurations on Cisco Umbrella (as an internal domain) and conditional forwarder in DC) are functioning as expected and being bypassed by Cisco Umbrella. The DNS in my network is VA IP of Cisco and not DC which should work as it is working for all internal domains of organization but not for those domains whose conditional forwarder is public dns. Has anyone encountered such an issue?
