    """
    Provides information to AWS about your VPN customer gateway device. The customer gateway is the appliance at your end of the VPN connection. (The device on the AWS side of the VPN connection is the virtual private gateway.) You must provide the Internet-routable IP address of the customer gateway's external interface. The IP address must be static and may be behind a device performing network address translation (NAT).
    For devices that use Border Gateway Protocol (BGP), you can also provide the device's BGP Autonomous System Number (ASN). You can use an existing ASN assigned to your network. If you don't have an ASN already, you can use a private ASN (in the 64512 - 65534 range).
    For more information about VPN customer gateways, see Adding a Hardware Virtual Private Gateway to Your VPC in the Amazon Virtual Private Cloud User Guide .

    Examples
    This example creates a customer gateway with the specified IP address for its outside interface.
    Expected Output:
    
    :example: response = client.create_customer_gateway(
        DryRun=True|False,
        Type='ipsec.1',
        PublicIp='string',

    :type DryRun: boolean
    :param DryRun: Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is DryRunOperation . Otherwise, it is UnauthorizedOperation .

    :type Type: string
    :param Type: [REQUIRED]
            The type of VPN connection that this customer gateway supports (ipsec.1 ).
            

    :type PublicIp: string
    :param PublicIp: [REQUIRED]
            The Internet-routable IP address for the customer gateway's outside interface. The address must be static.
            

    :type BgpAsn: integer
    :param BgpAsn: [REQUIRED]
            For devices that support BGP, the customer gateway's BGP ASN.
            Default: 65000
