Description
I am using the npcap-0.996 version, trying to capture the out packets of the PC of particular adapter.
I opened the pcap session in promiscuous mode with the pcap_open function and reading the packets continuously by pcap_next_ex function. Able to read the incoming packets but not able to read the out packets.

Research direction
Start by reproducing the capture on the particular adapter with pcap_open in promiscuous mode, then inspect the packets returned continuously by pcap_next_ex. Compare incoming and outgoing traffic and determine whether the missing outbound packets reflect an implementation problem or expected Npcap behavior; the issue is resolved when the cause and supported behavior are established.
