Configuring HA

1. Go to System > High Availability > Configuration.
2. Under HA Configuration, set Mode of operation to config primary if the FortiMail unit is the primary unit in the active-passive group. Select config secondary if the FortiMail unit is the secondary unit.
3. Enter a Shared password. This password must be the same for both the primary and secondary units.
4. Under Advanced options, set an HA base port value (20000 by default). This will be used for the heartbeat signal, and synchronization control, including data and configuration synchronization.
5. Click Create and double-click the entry created. For the primary unit, enter the secondary unit's IP address. If you are configuring the secondary unit, enter the primary unit's IP address.
6. Click Apply.
