I'm not aware of any open source firewalls for Windows. If you want to
perform your own firewall filtering, you'll have to learn the following:
1. Basic Windows Internals. Try reading "Windows Internals" by Mark
Rusinovich and David Solomon
2. Basic Windows I/O model. Plenty of material in the DDK docs (you
have the DDK, right?)
3. Windows kernel-mode debugger WinDBG
4. Depending upon what you're trying to accomplish, you'll also need a
good understanding of the TCP/IP protocols, possibly the datalink layer
packet formats, possibly WinSock, and maybe IPSEC.
5. Windows Filtering Platform (WFP) is the framework around which you
would create your firewall. WFP filters run in kernel-mode as device
drivers. There are 3 dozen inspection points where you can
examine/modify/discard/inject data coming into or going out of the system.

Starting from knowing nothing of the above, it will probably take you a year
to acquire the necessary knowledge and experience to create a firewall.

What problem are you trying to solve? You might be able to create rules in
the built-in Windows firewall. If not, then you'll need a consultant if you
want this done in any reasonable time frame.

Hi Brian,

> I'm not aware of any open source firewalls for Windows.

have a look at these projects, they all implement some sort
of firewall, some sort means the layer on which they operate:

http://sourceforge.net/projects/tdifw/
http://www.hsc.fr/ressources/outils/pktfilter/
http://wipfw.sourceforge.net/index.html
http://isafer.sourceforge.net/
http://sourceforge.net/projects/owasp/files/
http://www.delegate.org/delegate/
http://www.kobore.net/soft/pipmasq/

(More or Less) Free Code (See License!):
http://www.codeproject.com/KB/cpp/firewallpapi.aspx
http://www.codeproject.com/KB/IP/smfirewall.aspx
http://www.codeproject.com/KB/IP/drvfltip.aspx
http://beta.codeproject.com/KB/IP/PackyuetFilter.aspx
http://www.codeproject.com/KB/IP/Firewall_NET_C_.aspx

and propably the most powerful of them all:

http://force.coresecurity.com/

But i am not sure if the source code is any
longer available,...

And many many more (mine not included ;-)),...

There are many open source FW's and Example Code
published with different licenses. But all provide a great
means on learning either ring3 filtering/handling or ring0
filtering/handling of network data,...
