NimbostratusGTM iRule - cname
NimbostratusNm...got it. Use an 'A' record pool and if it returns 'up' from the EAV have the iRule respond directly with the CNAME, don't have it attempt to point to a pool to return the CNAME. Bazinga.
v13 is a four letter word.

NimbostratusThis is the closest thread I can find to my issue: 13.1.1 and Applications are moving into Azure. All that is supposed to be required is CNAME to Azure's CNAMEs but although this works on the external BIG-IP DNS with ZoneRunner something is not working with internal DNS Express which is getting it's records of a Windows server
The results look fine from a dig but no web access - Not FW as the browser responds with resolution error
$ dig @internal1 tst.wa.au q-opt any
