I am creating a new TCP SYN packet, and sending it to the network card. All this workds perfectly well, except the SYN-ACK from the remote host is being rejected by the OS (it’s sending an RST automatically). My assumption is that the local port # I am assigning is not known to the OS and the OS is not expecting traffic on the specified port.
My question then, is, using the WinPkFilter system, how do I query for or allocate a local (source) ethereal port number for use in creating my TCP connections in this fashion?
