-- Resets an attribute of an instance to its default value. To reset the @kernel@ or @ramdisk@ , the instance must be in a stopped state. To reset the @sourceDestCheck@ , the instance can be either running or stopped.
--
--
-- The @sourceDestCheck@ attribute controls whether source/destination checking is enabled. The default value is @true@ , which means checking is enabled. This value must be @false@ for a NAT instance to perform NAT. For more information, see <http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_NAT_Instance.html NAT Instances> in the /Amazon Virtual Private Cloud User Guide/ .
