Re: Detect proxy software - Internet access control

[Ivan Hernandez <ivan.hernandez () globalsis com ar>]

fine, usually HTTP Proxy servers add some kind of banner like
"Via: 1.0 proxy.myhome.com"
there are also NAT proxy implementations on WinXP, Win2K, Linux, BSD, 
and much others so i suppouse that if your passive fingerprint reveals 
different system versions for a same IP address you have different 
machines behind a NAT (of course, VMWare installed with another host OS 
can make the same for a single legitimate user).
You'll be always in doubt i suppouse...
