is changing FwpsInjectMacReceiveAsync() interfaceIndex parameter ok ?

apmattilapmattil Member Posts: 3

my problem is that I need to redirect hyper-v VM's traffic to our virtual driver.

now to redirect traffic to/from our virtual driver I change FwpsInjectMacReceiveAsync() and FwpsInjectNetworkSendAsync() interfaceIndex parameter to id of our virtual driver.

documentation says that it should be the same as what the callback with callbacks incomingValue.
e.g inFixedValues->incomingValue[FWPS_FIELD_INBOUND_IPPACKET_V4_INTERFACE_INDEX].value.uint32;

do you see any problems with this solution ?
