Hi im trying to make a packet filter in C++. The only point of it is to drop all packets sent and recieved, or allow all packets sent and recieved. And I need it to turn on and off by pressing F9. Can someone help me on maybe how to start ? i would appreciate the help

>>Can someone help me on maybe how to start ?
Depends. Are you comfortable with writing c++ programs? If no, then start by learning the language.

If you know how to write c++ programs, then what is your knowledge of socket program? None, then google for socket program tutorials.
