on the aironet access points there is a feature: PSPF - Publicly Secure Packet Forwarding. This feature blocks inter client communication. Is there a similare feature available for the WLC airespace products?
Under the controller menu->General there is an option for Peer to Peer blocking. That should be what you are looking for. Keep in mind that applies to all SSIDs. There is not a per-SSID option for blocking client to client traffic.
