Abstract
A method and system include a SDP controller in a SDP receiving a request from a first device for communicating with a second device. The second device is in the SDP. A firewall includes a connection table configured to map an identity of the first device and second device, and a filter table is configured to open and close ports. The SDP controller authenticates the first device, and provides the identity of the first device to the second device. The second device transmits a first packet to the first device. The firewall maps in the connection table, the identity of the first device in association with the second device. The first device transmits a second packet to the second device. The firewall determines that the identity of the first device is in the connection table for communicating with the second device and forwards the second packet to the second device.
