Bind NDIS filter driver to a NDIS Mux driver

Normally, you cannot bind a NDIS filter driver to a NDIS Mux driver. This is because usually a NDIS filter driver will specify FilterMediaTypes as

HKR, Ndi\Interfaces, FilterMediaTypes, , "Ethernet, TokenRing, FDDI"


On the other hand, NDIS Mux driver need to specify


HKR, Ndi\Interfaces, LowerRange, 0, "nolower"


The “nolower” is not in the filter driver’s FilterMediaTypes list, thus you need to add “nolower” into FilterMediaTypes list in order to bind a filter driver to a mux driver.



See here for the reference.
