    Gday folks,

    I know that the WAN IP is accessible to all public traffic.

    However If I'm running NAT on my private internal class C IP network, can wan based traffic detect which particular machine with its unique MAC address is actually engaged in the traffic on the wan? Or is the NAT device reporting its MAC to WAN comms?

    Depends on how you connect to the WAN. If you are connected directly, I would say yes. if you are NATed to a private address that is connected to the WAN, I say no. MACs are only used to map an ip address to a physical network card. If the network already has an IP to handle your connection, no MAC address is needed.
