More On Detecting NAT Gateways

Posted by timothy on from the check-your-terms-of-service dept.

tcom91 writes "The Slashdot article Remotely Counting Machines Behind A NAT Box described a technique for counting NAT hosts. A recently published paper Detecting NAT Devices using sFlow describes an efficient way of detecting NAT gateways using sFlow, a traffic monitoring technology built into many switches and routers. This technology could be used to enforce single host access policies and eliminate unauthorized wireless access points."

    And another thing ... do you know how stupid it is to directly connect your box to that cable/dsl modem thing with out at least hiding behind some kind of NAT?

    NAT is an ugly hack. It is the last thing you should be promoting to the dumbasses who don't know better than to listen to people like you.

    Go ahead and try it - be sure to run BlackICE or something so you can count how many times you get portscanned in an hour ..

    I've looked at what all packets come my way on my cable network, and honestly there isn't a whole lot of interesting stuff (at least not on a constant basis). And WTF is black ice? Some windows software garbage? Gee, you sound like quite the guru.
