Thank you for all answers. The major problem I'm facing is the lacking 
of documentation on that subsystem.
For example, how to create a policy. And after that?
My task is a bit easier, because I only need to use AH and not ESP.
Although a flexible solution would be of value :)

The kernel is still a bit unknown to me, so I'm having a bit of trouble 
into all the jargon you are using around.
But the few things I understood are being extremely helpful.

With that I must agree!
