Hey Guys,

Glad I found this thread, I have the same issue. I have a zone that is created via BIND and I configured a DNS Express for that zone (test.com for example). And within that BIND config I have a delegation for security.test.com going to amazon DNS servers. I tried this irule but it looks like it's not working. my version is 14.1.4

Thanks you! Hope you guys can help me. Ive been dealing for this issue for 6 months now 😄
