Using netfilter in linux, you can create rule for INPUT, OUTPUT, and FORWARD. You can also use -j QUEUE to send specific rule chain to the QUEUE. Then you may use libnetqueue_filter library to read the packets from queue and take necessary action. e.g. ACCEPT, or DROP them.

In windows, however, this task is not easy. WinPcap only send a copy of the packets to you. It means you cannot decide what to do with the incoming traffic (drop, accept, or queue them). You may want to use the winDivert, or WinPkFilter to do it.

For Windows check out WinPcap or for Linux the Netfilter project.
