We are installing a new Identify installation for a customer with  several locations, ( +/- 200)
the Wlan on the remote locations are going to use by Employees and customers. because of the expensive WAN connections we want that the customers are  the internet connections on the remote site, so we configure B@AP. And we also want to block the customer mobile unit to mobile unit traffic.  
Is there a way to block MU to MU traffic at the AP?
Thank you for your help
