/**
 * Create Vpn Connection Action Sample
 * Creates a new VPN connection between an existing VPN gateway and customer
 * gateway. The only supported connection type is ipsec.1.
 * The response includes information that you need to configure your customer gateway,
 * in XML format. We recommend you use the command line version of this operation
 * (ec2-create-vpn-connection), which lets you get the configuration information
 * formatted in a friendlier way. For information about the command, go to
 * ec2-create-vpn-connection in the Amazon Virtual Private Cloud Command Line Reference.
 * Important
 * We strongly recommend you use HTTPS when calling this operation because
 * the response contains sensitive cryptographic information for configuring
 * your customer gateway.
 * If you decide to shut down your VPN connection for any reason and then create a new
 * one, you must re-configure your customer gateway with the new information
 * returned from this call.  
 * @param Amazon_EC2_Interface $service instance of Amazon_EC2_Interface
 * @param mixed $request Amazon_EC2_Model_CreateVpnConnection or array of parameters
