Windows Packet Filter NDIS filter driver does not bind to WinTun network adapter because of the following in wintun.inf:
HKR, Ndi\Interfaces, LowerRange, , "nolower"
while in ndisrd_lwf.inf we have:
HKR, Ndi\Interfaces, FilterMediaTypes,,"ethernet, wan, ppip, bluetooth"
So there are two choices:
- Change wintun.inf ‘nolower’ to ‘ethernet’
- Add ‘nolower’ to the list of FilterMedia types in ndisrd_lwf.inf
As a side effect second option will cause Windows Packet Filter driver binding to the interfaces it normally would not bind to and therefore it is not supported by stock driver build.
