NAMED on cluster - zone transfers

Hi,
I have trouble with zone xfer from DNS on Microsoft server. I found very odd design flaw, when running named on cluster. NAMED will listen on IP addresses , which are added in cluster load script, but zone transfer operation communication is initiated from cluster node IP address. This is from security standpoint wrong and MS DNS server is refusing to start xfer, while it checks if there is DNS server on IP , which is sending request. It isn´t, because it´s listening on other IP addresses.

I don't have a chance to check this right now, but also have no reason
to consider much else than a bug / design flaw. Are yo able to open a SR?

Normally there is any in Listen-on property, former customers support partner put there IP addresses, adding cluster nodes IP addresses "solved" the problem.
