Gratuitous arp may not be learned if send as multicast. I know that on Nokia firewalls (now Checkpoint) you have a checkbox to accept mac address learning this way.
Check with wireshark/tcpdump what's happening (send/received) Mac address should be the virtual one and so does not change. Only switch have to learn that the virtual mac is now on another port. What is your switch/router model ? Manageable ?
