The value of the object tmnxNatPlLsnSubscriberLimit specifies the maximum number of subscribers per outside IP address. In case multiple port blocks per subscriber are used, the block size is typically small; all blocks assigned to a given subscriber belong to the same IP address; the subscriber limit guarantees that any subscriber can get a minimum number of ports. If this pool is used for Deterministic NAT, the value of this object must be a power of two, and not higher than 32768.
