Any technology can replace TDI in Win XP

NTDEV

Hi,
I would like some advices from someone who is familiar with TDI interface,
whether is it possible to do the following? I also would like to hear other
suggestions which can do the same thing.

  1. Convert packet destination IP address to another destination IP address,
    which is transparent to applications.

  2. Hook on DNS Domain Name query and return appropriate IP address.

These are the features I require for my new VPN project. I heard that LSP
Layered Service has a lot of problems and tried to avoid using this
technology.

Thanks for any suggestions!

Regards,
Sin Lam

The biggest problem with LSP in my opinion is the lack of solid
documentation.

However, LSP would do what you require quite easily. Have a look at this
LSP project that has full
source and a bit of documentation: http://www.komodia.com/

TDI filtering is even more problematic. Let’s start that it is undocumented.
