In the high availability system, the devices that act as slaves synchronize their settings with the master unit.
The main characteristic of the synchronization process, whether high availability is configured manually or automatically, are the following:
- You only need to assign a unique configuration IP for accessing the console for each slave device.
- You only need to configure the high availability parameters (Group, Password and mode) in the slave devices.

- The rest of the settings (filter rules, VPN settings, customization of warning texts, etc.) will be automatically received from the master device when configuration is synchronized.
- The configuration IP addresses of the units that make up the cluster must belong to the same logical range.

- The first parameter that the slave units synchronize with the master unit is the time. The time can be synchronized in the following ways:
- Automatic: The time is automatically configured with the master unit through NTP packets (UDP 123).
- Manual: The time is configured manually from System settings in the menu in the console, selecting System clock, System date and time, in the Manual adjustment section.
After the time has been synchronized in all the units in the cluster, the master will send the slaves the rest of the settings via SSH through TCP port 19.
