/**
 * Container for the parameters to the {@link com.amazonaws.services.ec2.AmazonEC2#createCustomerGateway(CreateCustomerGatewayRequest) CreateCustomerGateway operation}.
 * <p>
 * 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).
 * </p>
 * <p>
 * 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).
 * </p>
 * <p>
 * <b>NOTE:</b> Amazon EC2 supports all 2-byte ASN numbers in the range
 * of 1 - 65534, with the exception of 7224, which is reserved in the
 * us-east-1 region, and 9059, which is reserved in the eu-west-1 region.
 * </p>
 * <p>
 * For more information about VPN customer gateways, see
 * <a href="http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_VPN.html"> Adding a Hardware Virtual Private Gateway to Your VPC </a>
 * in the <i>Amazon Virtual Private Cloud User Guide</i> .
 * </p>
 * <p>
 * <b>IMPORTANT:</b> You cannot create more than one customer gateway
 * with the same VPN type, IP address, and BGP ASN parameter values. If
 * you run an identical request more than one time, the first request
 * creates the customer gateway, and subsequent requests return
 * information about the existing customer gateway. The subsequent
 * requests do not create new customer gateway resources.
 * </p>
