The situation is deliberate, yes. IPsec is done in what you could
call the xfrm subsystem, not netfilter. To that end, the only
suggestion I could give is that you create a new xfrm policy/state
from esp where esp is split into your encryption and signing
"targets".

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.
It kinda brings me the question why the ipsec transformation is
not done with an xtables target instead; that would also give
handy access to connection tracking if needed.
With that I must agree!
