Description

Hello recently I realised that Wireshark (Npcap based) wasn't showing diverted NAT packets from a router app called Connectify. Which is implemented using WinPkFilter.
I can't see arriving packets to the nat Interface, only the ones which are directed to its own ip.
It seems that winpkfilter is hooking or something lower than npcap.

I would like to know if is possible to get those packets or whats happening.

Thanks, Greetings

PD: Haven't tried Windivert based apps but I may asume the same behaviour because they're implemented via WFP with same purposes.

Research direction

Start by reviewing the issue’s description of Npcap, WinPkFilter, and WFP packet interception, then determine whether diverted NAT packets are expected to be visible at Npcap’s capture layer. Done means a confirmed explanation of the interception behavior and, if supported, a clearly identified entry point or limitation.
