## Symptoms

- * Network Address Translation (NAT) information (Xlate) does not appear in logs for a specific NAT rule, while logs for other NAT rules in the same security policy display this information correctly.
* Packet capture using tcpdump confirms that NAT is functioning and traffic is being translated as expected.
* No NAT information appears in the logs for the affected rule, even though log generation settings and log options are set to "per Connection" or "per Session".
* For the same connection, some logs show the NAT rule and rule ID, while others do not. Log IDs differ between logs with and without NAT information.

This problem was fixed. The fix is included starting from:
