A method and system for distributed collaborative firewalling in a wireless wide area communication network including a plurality of controllers, comprises a binding table that is built by the controller in response to receiving identifiers of wireless clients being served by the controller, where the binding table lists the wireless clients associated with each access port under control of the controller. A processor of the controller is operable to apply stateless firewalling on wireless communication traffic from a wireless client using the binding table, and applying, by each access port, stateful firewalling on the wireless communication traffic from the wireless client.
