I am thinking about programming my own firewall (sounds like a rather large task, but whatever) and I have googled the subject. Most of the results were using linux, however, I only have access to windows at the moment. Do you guys have any ideas on how to at least close some of the ports on my computer, or better yet, an example of some code that I could study? From what I have read, I would need another library or two in order for me to program the firewall...Any help would be appreciated... thanks.
