6.3Defect ID: PAN-321573
( HA Active-Active firewalls only ) Fixed an issue where High Availability (HA) session synchronization did not occur between the active primary and secondary firewalls, which prevented sessions from properly synchronizing across the HA pair. This occurred after a firewall upgrade. With this fix, HA session synchronization between the active primary and secondary firewalls was restored.
6.3Defect ID: PAN-317598
( Firewalls in active/active HA configurations only ) Fixed an issue where NAT failures occurred due to the IP pool not releasing unused resources in the Active Secondary firewall. This occurred because the secondary firewall attempts to release a Persistent DIPP NATed port that was originally allocated by the NAT policy from first firewall, leading to a ownership mismatch during the session teardown process.
