-- | 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 can't 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 <http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_VPN.html Adding a HardwareVirtual Private Gateway to Your VPC> in the /Amazon Virtual Private Cloud UserGuide/.
