      OK, I think I have the answer, but after my first experience bridging a wireless card and a NIC, every time the FW boots, I get a prompt in Windows re. "Do I want my PC to be discoverable on this network". The network counts keep incrementing (i.e. Network n+1), and after installing arpwatch for another reason, I've found ref's to old MAC/new MAC in the arpwatch messages. I'm guessing I should just paste the new MAC into the spoof MAC field of the bridge member to hard set it? That right?

        Yes, exactly. The bridge interface MAC is generated at each boot unless you set one in the gui. That means if you're using it as the dhcp server clients will see it as a new network every time.
        So set a MAC to prevent that.
