Actions
The actions to take on a packet that matches one of the stateless rule definition's match attributes.
public string[] Actions { get; set; }Property Value
System.String[]
Remarks
You must specify a standard action and you can add custom actions.
Network Firewall only forwards a packet for stateful rule inspection if you specify aws:forward_to_sfe for a rule that the packet matches, or if the packet doesn't match any stateless rule and you specify aws:forward_to_sfe for the StatelessDefaultActions setting for the FirewallPolicy .
For every rule, you must specify exactly one of the following standard actions.
Additionally, you can specify a custom action. To do this, you define a custom action by name and type, then provide the name you've assigned to the action in this Actions setting.
To provide more than one action in this setting, separate the settings with a comma. For example, if you have a publish metrics custom action that you've named MyMetricsAction , then you could specify the standard action aws:pass combined with the custom action using [“aws:pass”, “MyMetricsAction”] .
MatchAttributes
Criteria for Network Firewall to use to inspect an individual packet in stateless rule inspection.

System.Object
Remarks
Each match attributes set can include one or more items such as IP address, CIDR range, port number, protocol, and TCP flags.
