Opened: Aug 31, 2017
Severity: 3-Major

Symptoms

When the number of addresses configured on an lsn-pool or source-translation object is fewer than the number of tmms in the system, there a chance for the outbound connection's translation to fail.

Impact

Sub-optimal performance. May cause functional/validation tests to fail.

Conditions

NAT66 configured with a single translation address configured in the lsn-pool or source-translation object.

Workaround

Configure at least as many translation addresses on your lsn-pool or source-translation object as there are tmms on the BIG-IP system.

Fix Information

NAT66 translations no longer fails when only a single translation address is configured.
