Re: Block OS Detection

OpenBSD's PF has been ported to Windows (pre-Vista) as part of a free 
firewall/endpoint security software. It is part of research work and in 
beta state (regular YMMV disclaimer) but I know it has been installed used 
on production servers for quite some time. The port of OpenBSD's PF 
provides a fully-featured and stable bidirectional statefull firewall that 
some found useful to have on windows systems.
