Windows Firewall

Greetings all,

I am attempting to build a windows-based firewall for my box, however I am short on info. I am specifically looking for generic architecture docs and code samples. The only references Google provided were those pertaining to commercial firewalls.

If you know of any links, please post them here. Thank you in advance.

I wasn't able to find any links, but you might consider buying Building Internet Firewalls by Chapman and Zwicky. It's supposedly a classic reference for building firewall software.
