You can select the interface to send and receive inter-HA traffic from within the Web User Interface (WUI) of the shared IP address:
- In the main menu, select System Configuration > HA Parameters.
- The HA Update Interface setting is used for sending HA configuration updates using TCP/6973 between units. Modify it if needed.
If you have enabled L7 persistency updates or L4 TCP connection updates, an additional HA Multicast Interface option will also be available.
