</span>I've updated the trap-any branch (based on the trap-acquire-tracking<br>
branch). Due to the changes in 5.3.0 (reqids don't identify CHILD_SAs<br>
anymore) no additional reqids are required and no awkward SA deletion is<br>
needed anymore. So that removes one of the reservations I had about the<br>
previous iteration of the patch.<br>
<br>
And with the above patch it is actually already possible to limit the<br>
remote hosts to specific subnets/IPs. Just set `rightsubnet`<br>
accordingly. I added a test scenario (ikev2/trap-any) in that branch<br>
that illustrates this (see host dave).<br>
<br>
Let me know if that works for you.<br>
<br>
Regards,<br>
Tobias<br>
