I had a similar problem to this on one of my VMs. It had to do with the way the vm box was connected to the lan. I had to set the vm nic load balancing to 'route based on IP hash' Until I did that, I had all kinds of strange issues with IP addresses mapping back to the wrong mac addresses. Not sure if it applies to your situation, but if your vm box has multiple network lines trunked up to a switch it might be something to look at.
