Example

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import { aws_networkfirewall as networkfirewall } from 'aws-cdk-lib';
const tCPFlagFieldProperty: networkfirewall.CfnRuleGroup.TCPFlagFieldProperty = {
  flags: ['flags'],

The ones that are set in this flags setting must be set in the packet.
The ones that are not set in this flags setting must also not be set in the packet.
