LTM using outside DNS eventhough internal DNS configured

Hello Everyone, we are experiencing some problem with DNS used by LTM. LTM is configured with internal DNS server IP, even though we can see in the firewall logs that one of the self IP making connection to outside DNS. tcpdump IP A.B.C.D.24689 > 81.201.209.55.domain: 5784 [1au] AAAA? scribona.com. (41) IP 81.201.209.55.domain > A.B.C.D.24689: 5784 Refused- 0/0/1 (41)

  • I would suggest uploading a qkview to ihealth and opening a support ticket. Support will be able to look at your configuration and tell you what is happening. Without your configuration it is unlikely that we will be able to tell you why your BigIP is not using the expected DNS server.
