Hi,

I just read an article in a german computer magazin c't
about the possibility of counting NATed hosts behind a
router (http://www.research.att.com/~smb/papers/fnat.pdf). 
This is possible because on most systems the IPid is a 
sequence. 
Not so with FreeBSD and OpenBSD, they use random numbers. 
Anyone knows if the same applies to NetBSD?  Linux?


Regards,

  Michael
