I know how MAC address filtering works. I was Cisco certified. I think you are misunderstanding what he wants. He wants to know how the OPERATING SYSTEM is being filtered. Apparently, the network in question is filtering out the Windows OS but allowing the MAC OS. Not MAC address. All I'm saying is that a network cannot identify your OS with only your IP or MAC address.
