The address range cannot overlap with the local CIDR of the VPC in which the associated subnet is located, or the routes that you add manually. Changing the address range will replace the Client VPN endpoint. The CIDR block should be /22 or greater.

  • server_certificate_arn (str) – The ARN of the server certificate.

  • authorize_all_users_to_vpc_cidr (Optional[bool]) – Whether to authorize all users to the VPC CIDR. This automatically creates an authorization rule. Set this to false and use addAuthorizationRule() to create your own rules instead. Default: true

  • client_certificate_arn (Optional[str]) – The ARN of the client certificate for mutual authentication. The certificate must be signed by a certificate authority (CA) and it must be provisioned in AWS Certificate Manager (ACM). Default: - use user-based authentication

  • client_connection_handler (Optional[IClientVpnConnectionHandler]) – The AWS Lambda function used for connection authorization. The name of the Lambda function must begin with the AWSClientVPN- prefix Default: - no connection handler

  • description (Optional[str]) – A brief description of the Client VPN endpoint. Default: - no description

  • dns_servers (Optional[Sequence[str]]) – Information about the DNS servers to be used for DNS resolution. A Client VPN endpoint can have up to two DNS servers. Default: - use the DNS address configured on the device

Return type


add_flow_log(id, *, destination=None, traffic_type=None)

Adds a new Flow Log to this VPC.

  • id (str) –

  • destination (Optional[FlowLogDestination]) – Specifies the type of destination to which the flow log data is to be published. Flow log data can be published to CloudWatch Logs or Amazon S3 Default: FlowLogDestinationType.toCloudWatchLogs()

Return type


add_gateway_endpoint(id, *, service, subnets=None)

Adds a new gateway endpoint to this VPC.

  • id (str) –

  • service (IGatewayVpcEndpointService) – The service to use for this gateway VPC endpoint.

  • subnets (Optional[Sequence[SubnetSelection]]) – Where to add endpoint routing. By default, this endpoint will be routable from all subnets in the VPC. Specify a list of subnet selection objects here to be more specific. Default: - All subnets in the VPC

Return type


add_interface_endpoint(id, *, service, lookup_supported_azs=None, open=None, private_dns_enabled=None, security_groups=None, subnets=None)

Adds a new interface endpoint to this VPC.

  • id (str) –

  • service (IInterfaceVpcEndpointService) – The service to use for this interface VPC endpoint.

  • lookup_supported_azs (Optional[bool]) – Limit to only those availability zones where the endpoint service can be created. Setting this to ‘true’ requires a lookup to be performed at synthesis time. Account and region must be set on the containing stack for this to work. Default: false

  • open (Optional[bool]) – Whether to automatically allow VPC traffic to the endpoint. If enabled, all traffic to the endpoint from within the VPC will be automatically allowed. This is done based on the VPC’s CIDR range. Default: true

  • private_dns_enabled (Optional[bool]) – Whether to associate a private hosted zone with the specified VPC. This allows you to make requests to the service using its default DNS hostname. Default: set by the instance of IInterfaceVpcEndpointService, or true if not defined by the instance of IInterfaceVpcEndpointService

  • security_groups (Optional[Sequence[ISecurityGroup]]) – The security groups to associate with this interface VPC endpoint. Default: - a new security group is created

  • subnets (Optional[SubnetSelection]) – The subnets in which to create an endpoint network interface. At most one per availability zone. Default: - private subnets

Return type


add_vpn_connection(id, *, ip, asn=None, static_routes=None, tunnel_options=None)

select_subnets(*, availability_zones=None, one_per_az=None, subnet_filters=None, subnet_group_name=None, subnet_name=None, subnets=None, subnet_type=None)

Return information on the subnets appropriate for the given selection strategy.

Requires that at least one subnet is matched, throws a descriptive error message otherwise.

  • subnet_group_name (Optional[str]) – Select the subnet group with the given name. Select the subnet group with the given name. This only needs to be used if you have multiple subnet groups of the same type and you need to distinguish between them. Otherwise, prefer subnetType. This field does not select individual subnets, it selects all subnets that share the given subnet group name. This is the name supplied in subnetConfiguration. At most one of subnetType and subnetGroupName can be supplied. Default: - Selection by type instead of by name

  • subnet_name (Optional[str]) – (deprecated) Alias for subnetGroupName. Select the subnet group with the given name. This only needs to be used if you have multiple subnet groups of the same type and you need to distinguish between them.

  • subnets (Optional[Sequence[ISubnet]]) – Explicitly select individual subnets. Use this if you don’t want to automatically use all subnets in a group, but have a need to control selection down to individual subnets. Cannot be specified together with subnetType or subnetGroupName. Default: - Use all subnets in a selected group (all private subnets by default)

  • subnet_type (Optional[SubnetType]) – Select all subnets of the given type. At most one of subnetType and subnetGroupName can be supplied. Default: SubnetType.PRIVATE (or ISOLATED or PUBLIC if there are no PRIVATE subnets)

Return type




AZs for this VPC.

Return type



The environment this resource belongs to.

For resources that are created and managed by the CDK (generally, those created by creating new class instances like Role, Bucket, etc.), this is always the same as the environment of the stack they belong to; however, for imported resources (those obtained from static methods like fromRoleArn, fromBucketName, etc.), that might be different than the stack they were imported into.

Return type



Dependable that can be depended upon to force internet connectivity established on the VPC.

Return type



List of isolated subnets in this VPC.

Return type



The construct tree node for this construct.

Return type



List of private subnets in this VPC.

Return type



List of public subnets in this VPC.

Return type



The stack in which this resource is defined.
