GTM 11.5.1 does not respond DNS queries anymore
Hello folks,
Yesterday, I upgraded a GTM from 11.2.1 to 11.5.1. It seemed that every configuration object was migrated from the old version to the new one, but the DNS name resolution failed. I have read the release notes of F5 and there is nothing about this kind of issues. The GTM is resolving a delegated subdomain which is located in the ISP provider's DNS. So. do I need to change something in the namedb or in the listener conf?
The traffic capture says: query response, server failure.
all comments and recommendations will be welcome.
Thanks in advance.
Omar
