Appearance

v2.276.0

Experimental

@aws-cdk/aws-ec2-alpha is an experimental (alpha) package: its API may change in any release, without a major version bump.

NatConnectivityType Enum ​

Indicates whether the NAT gateway supports public or private connectivity.

The default is public connectivity. See: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-ec2-natgateway.html#cfn-ec2-natgateway-connectivitytype
