I... guess I would know how to do it, but pardon me, I couldn't find
what I need on the vast Internetz. I know how to mark packets and to
route them accordingly, but I might be missing something here, because
I'm still stuck at a point where iproute tells me that the remote
network is unreachable.

I know you're not here to provide a bunch of commands to help me get
started, but maybe just a "recipe" ? Something like "first, mark your
packets coming from blah and using bleh, then add a rule to handle
these, then... etc."

The thing is that I looked at the archives of this list and I found a
schema that you provided, showing the whole netfilter chains with IPSec
in the middle... but even then, I'm not sure I can successfully use that

Thanks anyway !
