Block access to wifi (network) adapters

NTDEV

Hello!
I wrote my problem on Windows community for hardware developers, but I did’t answer.

I develop driver filter for pnp network adatpers ({4D36E972-E325-11CE-BFC1-08002BE10318} - Upper filter in registry), and want to block all data-transfering. But I faced with few problems :

  • my driver attached to strange devices : \Device\NDMP9(Root\MS_PPPOEMNIPORT), \Device\NDMP7(Root\MS_NDISWANIP), etc.
  • my driver don’t get any IRP when I using internet over adapters (IRP_MJ_CREATE, IRP_MJ_DEVICE_CONTROL)
    How I can resolved data-transfering block problem? How I can attach to only physical adapters(not Root\MS_PPPOEMNIPORT…)?

You should write a NDIS Lightweight Filter (LWF) to filter on the network
stack. Read the NDIS documentation.

At a somewhat higher level you can filter datagrams using the Windows
Filtering Platform (WFP). Read the MADN documentation for WFP.

The NDIS packet interface isn’t IRP based. Instead, it uses a “NDIS Library”
that is used for packet transfer.
