Description
Hi,
I am using NpCap to duplicate incomming UDp packets to another port:
Lets say I have incomming udp packets on port 25000, so I will duplicate this packet and send it to 27000 port.
When I was using WinPCap everything worked as I wanted too, but with WinPCap it almost everytime ended up with BSOD afetr some time.
So I upgraded to NpCap, but now I cannot capture sent packets in applications. I can see them via Wireshark, but not in my C# application using UdpClient().
Cna you help me with this problem? I am thinking its NpCap problem, because with WinpCap it worked fine (if I am not counting BSOD later)
Thanks a lot

Research direction
Start by reproducing the reported setup: duplicate incoming UDP packets from port 25000 to port 27000 with Npcap, then compare Wireshark captures with receipt by the C# UdpClient application. Determine whether the duplicated packets reach the application, and document the cause or a confirmed resolution for the difference from WinPcap.
