Here is the senario. i got 2 network adapters in my computer.I want to configure one to be ‌exclusively used by a specific program‌ while ‌hiding it from the user‌ and ‌excluding it from system routing. 

i found FWPM_LAYER_IPFORWARD_V4 layer and API FwpsInjectForwardAsync0. Can i use FwpsInjectForwardAsync0 to inject to specific NIC in FWPM_LAYER_IPFORWARD_V4 layer.

I saw in doc " The FwpsInjectForwardAsync0 function injects packet data into the forwarding data path." What's the meaning of forwarding data path? does it mean ip route forward ?
