In an HA setup, the primary CloudGen Firewall stays active until a serious problem occurs. If virtual servers and services must be shut down (for example, for system maintenance), you can do a manual failover to transfer all virtual servers to the secondary (backup) unit. On the ADVANCED > High Availability page, you can manually execute an HA failover on the firewall that is currently active. If the firewall is not part of an HA cluster, the Manual Failover option is disabled.
Settings NOT Synced Between Firewalls in a High Availability Cluster
The following settings are unique to each firewall in the HA cluster and are not synced:
- HTTPS Port
- Management Interface Configuration.
- Content of DNS Cache
- Dynamic Interfaces
