Bug ID 760393: GARP is not sent from newly active device after failover for FW NAT policy rule's dest prefixes

Last Modified: Nov 07, 2022

Affected Product: See more info
BIG-IP AFM(all modules)

Known Affected Versions:
14.1.0, 14.1.0.1, 14.1.0.2, 14.1.0.3

Fixed In:
15.0.0, 14.1.0.5

Severity: 3-Major

After failover, there is no GARP from the newly active device for FW NAT policy rule's dest prefixes.

After failover traffic can fail/degrade.

Configure FW NAT policy rules with proxy arp enabled for destination prefixes. After failover no GARP is sent for those destinations prefixes.

No workaround other than forcing the initial active HA device to be active again.

The system now sets the high availability (HA) unit correctly for FW NAT policy.
