Stateful default actions in your firewall policy

In your firewall policy configuration, you indicate how Network Firewall should handle packets that don't match any stateful rule group that's defined for the policy. Note that you can provide this configuration regardless of whether you define stateful rule groups for the policy when you use strict rule order.

For more information about stateful default actions for rule groups, see Action order.
