Bug ID 428750: translation-port-range change does not trigger deterministic NAT state log

Last Modified: May 29, 2024

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

Known Affected Versions:
11.4.0, 11.4.1

Fixed In:
11.5.0, 11.4.1 HF2, 11.4.0 HF4

Opened: Aug 23, 2013

Severity: 3-Major


Changing LSN Pool translation-port-range does not generate deterministic NAT state log entry to be use for reverse/forward lookup. Reverse lookup with dnatutil using the new port range will fail.


Reverse lookup using dnatutil after changing translation-port-range of LSN Pool.


Change LSN Pool translation-port-range, perform reverse lookup using dnatutil in the new port-range.


Change other aspect of LSN Pool, e.g., members.

Fix Information

Changing LSN Pool translation-port-range for LSN Pool of deterministic mode will correctly trigger logging of deterministic NAT state information
