[CAUSE] Such a change may be caused by a modification of the tmnxNatDetPlcyTable or the tmnxNatDetMapTable. [EFFECT] Traffic flows of one or more given subscribers, subject to NAT, may be assigned a different outside IP address and/or outside port. [RECOVERY] Managers that rely on the offline representation of the Deterministic NAT map should get an updated copy.
