DNS Express Query Refused
I have a strange one. I have a DNS Express zone which has been transferred successfully. I can see the zones if I performa dnsxdump on the GTM. I have a DNS profile with DNS Express enabled; BIND/named disabled. I also have a default pool attached pointing to Google DNS servers.
I can resolve to external FQDNs without a problem (the traffic gets pushed to the Google pool). But internal FQDNs do not resolve (I get a QUERY REFUSED error). If I disable DNS Express, the internal FQDNs are pushed to the Google servers and I get a NXDOMAIN (which I expect).
So why is my DNS Express refusing queries??? Am I missing something?
