Netfilter can help but you'll have to install Linux in your system. We
don't have any plan to port it to windows, probably we'll do it for Hurd
once it gets stable.

Actually I already had it running on windows using colinux, but to be
really useful I had to write a network driver that steals away packets
from windows and reinjects them once they passed through colinux (a
horrible experience). Don't have anything of that stuff anymore though.

It would be simplest to put another machine in front of the Windows box that
does the packet mangling. Or you can move Windows into a virtual machine.
