By default, which action is assigned to the interzone-default rule?

Allowing interzone traffic by default would pose a significant security risk, as it would expose internal networks to unauthorized access without specific policy enforcement.

The default security posture for firewalls is to deny interzone traffic, ensuring that only explicitly permitted communication can occur between distinct network segments, following a zero-trust principle.

While 'reset-client' is a possible action, it is not the default for the interzone-default rule, which typically performs a silent deny to avoid revealing network topology.

Similar to 'reset-client,' 'reset-server' is an action, but the default for the interzone-default rule is a silent denial of unpermitted traffic.
