I took a crack at ipfw for Windows a while back but I stopped because the one I
found only had a 32-bit build


It turns out theres is another open source implementation of ipfw here


The site notes both 64-bit and 32-bit support for Windows 7. I successfully
installed it for Windows 7 64-bit, detailed here


However the next challenge is running 2 users. Apparently Cygwin "su" has never


and the suggested workaround is to install "sshd". I gave up at this point, but
I thought I would share my findings. Currently I am using "RtmpDumpHelper" to
capture streams but with "ipfw" we could have an open source solution.
