Applies to all Barracuda SSL VPNs, firmware 1.5 and higher.
Answer:The Barracuda SSL VPN has a feature called Simple High-Availability that can be used to cluster a group of SSL VPNs with one system being the HA Master. This cluster exists without a Load Balancer regulating connections.
Simple High-Availability can be configured by the following method:
- Configure the Shared Secret. As with a standard clustering environment the Shared Secret needs to be configured and set the same for all units in the cluster. Go to ADVANCED > Linked Management and set the Shared Secret and Save the changes.
- Set the Clustered Systems. Add the IP address of
the SSL VPN that this unit will be clustering with. The current system’s
configuration will be replaced with a copy of the configuration from
the specified unit.
- Ensure that the correct unit is in use, and that the target system is configured correctly to avoid any accidental configuration removals.
