Re: How to intercept IP packet from an application ???

simtouch,

I don't think this can be achieved using the CLR libraries.

What part of the packet are you trying to modify?

If you're just trying to wrap the data or modify source / destination headers, I'd search for a NAT solution that's written in .NET (i doubt there is one), it should help you get closer.

I think other people have mentioned this before, but i'll say it anyways. This isn't an easy undertaking.

Good luck,

Thank you

Hi,
If you need only to monitor packets, not to actually drop or modify,
there is a C# sample available at:
http://www.mentalis.org/soft/projects/pmon/

It's done through opening raw socket and setting socket IO control to
SIO_RCVALL. It's user mode approach, no drivers are necessary.
