Help regarding TDI..

Hi all,

I have the following question regarding writing TDI drivers.

  1. Can we write a TDI filter driver which can block TCP packets from
    reaching user applications selectively?

  2. How to set the TDI filter driver - ordinarily a filter driver is set
    using the IoAttachDevice () function. Am I correct? If so, can I use the
    same methjod to set my TDI filter driver?

Thanks and Regards
Sathya.
