6. Events will not be generated for “hidden” firewall rules. At the time of writing,
there are two implicit “hidden” firewall rules that are not displayed but act as if
they were the last two rules in the Firewall Rule table. These are:
Permit from this-device to ANY zone ANY protocol
Block from ANY zone to ANY zone ANY protocol
These rules do not generate log entries or syslog messages.
To enable the Firewall Analyzer to monitor events that would be generated by
these rules, two explicit rules must be created as the last two rules in the Firewall
Rule table and syslog logging must be enabled on both of them.
