Closing & Stopping Port Connections

Hi,

Im making a small security program and im not to sure how i would break a connection a port. Say there was an established connection on port 60, how could i close that connection.

And i assume to stop connections on a certain port i would just listen then do nothing when a connection is recived. Am i correct?

Thanks

I would just process the WM_SOCKET_NOTIFY msg's and call a close on any socket/port that is not needed (assuming you know what ones are going to be connected).

Or open a socket on these ports and close as soon as a connect msg (FD_CONNECT) is received.

If you want to keep the socket open just flush the incomming buffer as soon as you get the read.
