Deterministic NAT state from multiple TMMs can be interleaved in LTM log, making dnatutil unable to use the state information for reverse mapping.
Reverse mapping using interleaved deterministic NAT state log entries in the LTM log could be incorrect.
Configuration change to LSN Pool with deterministic NAT mode while BIGIP is serving connections.
Capture and fix interleaved log entries for deterministic NAT, and use the fixed log entries for reverse mapping.
Deterministic NAT state information will be logged from one TMM when configuration changes.
deterministic NAT configuration state information will now be logged once per change in configuration.
