Yes, you understand me correctly.
I’m not owner of any license.
I try to test WinPKFilter.
Why only TCP/IP adapters can be filtered?
For example, you can add some flag to internal structure of packet in driver code and when program try send non TCP/IP packet to stack, driver can detect this by flag and just drop this packet…
Somtimes need simply filter any incoming packets and filtering of non TCP/IP adapters can help in this case…
In my case this is transit packets.
Thank’s for answers.
