// Provides information to Amazon Web Services about your customer gateway device.
// The customer gateway device is the appliance at your end of the VPN connection.
// You must provide the IP address of the customer gateway device’s external
// interface. The IP address must be static and can 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. For more information, see Customer gateway
// options for your Site-to-Site VPN connection
// (https://docs.aws.amazon.com/vpn/latest/s2svpn/cgw-options.html) in the Amazon
// Web Services Site-to-Site VPN User Guide. To create more than one customer
// gateway with the same VPN type, IP address, and BGP ASN, specify a unique device
// name for each customer gateway. An identical request returns information about
// the existing customer gateway; it doesn't create a new customer gateway.
