I don't know what a "loadbalanced group" is - do you mean that you configured 'Server Load Balancing' in 'Network Security'?
If so, then I think your NAT rule is capturing the traffic before 'Load Balancing' gets a chance to work. Just disable the NAT, and the load balancing rule, if correctly configured, should do what you seem to want.
Your question is interesting. I didn't realize that Exchange servers in a DAG were, in effect, "clustered" instead of providing standby backup for each other in the event of failure of one server.
