Controller Based WLANs

Q:

Why the controller doesn't display the call details with NAT enabled?

Currently, Aruba controller doesn't display the call details with NAT enabled as its not supported in the controller. 
To have the call displayed in the controller, we either have the client gateway outside the controller or if it we client gateway as the Aruba controller then we need to create return route for the clients network in the controllers gateway device. 

Any outputs related to UCC will not be displayed with NAT enabled.
