Configuring HA

1. Go to System > High Availability > Configuration.
2. Under HA Configuration, set Mode of operation to config master if the FortiMail unit is the primary unit in the active-passive group. Select config slave 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 master unit, enter the slave unit's IP address. If you are configuring the slave unit, enter the master unit's IP address.
6. Click Apply.
