title: C#/C++ Capture local machine ip packet and drop it
body: <p>I am working on a firewall project. So far I succeed to block packets by ip basis which is I done by windows filtering platform. But my customer does not want to block the whole ip. He wants to block specific url. So now I need to capture each packet and read it. So far I can do that by C# raw socket. But I dont know how to drop that specific packet. Please help me out on that.</p>
