WinPcap does not provide any information regarding the direction of the packet. You will need to get this information by looking at stuff like the source and destination MAC address of the packet.

Have a nice day

Hi all


I would like to know if the packet received from pcap_next_ex() is an input packet or an output one?


Thanks for your help.
