Show packets blocked by Block private networks or Block bogon networks?

[srynoname]

In the past I stumbled over the options Block private networks and Block bogon networks, especially the first of them.

The tricky thing is that when packets are blocked through this rules, it's not shown in the firewall log.

Any way to change this? For normal firewall rules there's an option for this, for those two "special rules" (Block private / bogon networks) there seems to be none?
Thanks for any hint!

On System Log there is an option on the firewall tab "Show packets blocked by default rule". Perhaps this shows the blocked packets of this kind of rule.
