                Session direction (inbound or outbound) is

            specified by a network manager, and provides a non-volatile
            'handle' for the instance.

            On the first instantiation of a NAT instance, the value of
            natInstanceAlias associated with that instance is the
            zero-length string.  As and when a value is written into an
            instance of natInstanceAlias through a network management
            set operation, then the agent must retain the supplied value
            in this obejct instance associated with the same interface
            for as long as that NAT instance remains instantiated,
            including across all re-initializations/reboots of the
            network management system, including those which result in a
            change of the interface's natInstanceIndex value.

            An example of the value which a network manager might store
            in this object for a NAT instance is the name/identifier of
            the interface that brings in internal traffic for this NAT
            instance or the name of the VRF for internal traffic.

            An agent may choose to provide read-only access if the agent
            itself assigns an identifier for the NAT instance. An agent
            which supports write access to this object is required to
            keep the value in non-valite storage, but it may limit the
            length of new values depending on how much storage is
