Well of course my routers have two Macs.  One for wired and a different one for wireless.  These are Linksys routers with DD-DRT firmware.  The Macs are configurable as well.  But I just leave them the stock Mac of the router.  By spoofing I mean that, the gateway listed in NIS is just two numbers off on two different column of  the address.  like changing a 55 to a 56 and a 61 to a 62.  But technically this is a different mac.   I don't use wireless anymore.  I know the mac of all my hardware.  And this appears to be a "semi-spoof" on the routers wired lan.  At first glance, it looks the same, but not.  When this event happens, web pages take longer to load, as if filtered.  CISPA is not started yet, it it?
