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."
