Well, if the backdoor is able to enable logging in the packet filter
(i.e. configure the packet filter) it should also be able to add some
(as qualified as needed) pass rule, shouldn't it?
This should be far less noisy, far less performance consuming and
not more noticeable than the modification of other settings.
