recording firewall rules it is currently using. When you are using 80% or
less of the storage space, the bar is green. When the amount of space
used is over 80%, the bar is red.

which you want to configure firewall rules.

apply to traffic traveling in the selected packet direction. The firewall rules
that you configure (summarized below) take priority over the general
firewall action settings in the General screen.
