CARP Address showing Master on both FWs
I have run into this a few times (some times I forget about it until the next time too) and I have not seen the answer here (at least the ones I have read, didn't want to duplicate an answer). If you have a problem with CARP on VMware, make sure your Port Group security is set to allow Promiscuous mode and Forged transmits. MAC address changes can be set to Reject.
That's called out in the documentation in several places
