Firewall application developed using Packet Filtering API.

Introduction

When I published my articles about firewall development, I received some e-mails about how to develop a complete firewall solution using the methods described. With this tool I want to give these users an easy example of packet filtering utility.

In this solution I have used Packet Filtering API for Microsoft Windows 2000 and above. I have developed a MFC class wrapper for this API. With this class, I make a simple MFC application that allows a user to set filter rules in local interfaces.

If you want to know more about Packet Filtering API, you can read my article Packet Filtering in .NET. Feel free to e-mail me if you want to know more about this application.
