Last Modified: Jul 12, 2023

Affected Product(s):
BIG-IP CGN(all modules)

Known Affected Versions:
11.3.0, 11.4.0

Opened: Oct 24, 2013

Severity: 3-Major

Symptoms

When using dnatutil on deterministic NAT states from 11.3/11.4 HSL (Splunk/Syslog), dnatutil is unable to match correctly using time when provided with --start_time/--end_time, if the log host and BIG-IP is not in the same timezone.

Impact

dnatutil, when use with --start_time/--end_time.

Conditions

When using dnatutil on a log host with a different timezone than the BIG-IP, and parameter --start_time/--end_time is provided for timestamp matching.

Workaround

1) Use dnatutil without --start_time/--end_time 2) Change timezone of the log host to be the same of that of the BIG-IP system.

Fix Information

None
