Clusters

All VPN Gateways are members of a cluster. A cluster can consist of one single VPN Gateway or a group of NVGs that share the same configuration parameters. There can be more than one NVG cluster in the network, each with its own set of parameters and services. If the VPN Gateway is used for SSL Acceleration, each cluster can be set up to serve different real servers.

New and Join

Each time you perform an initial setup of an VPN Gateway and select new in the Setup menu, you create a new cluster which initially only has one single member. You can add one or more VPN Gateways to any existing cluster by performing an initial setup and select join in the Setup menu.

Configuration is Replicated among Master NVGs

The configuration parameters are stored in a database, which is replicated among the VPN Gateways designated as masters in a cluster. By default, the first four VPN Gateways in a given cluster are set up as masters.

Additional NVGs are automatically set up as slaves, which means they depend on a master NVG in the same cluster for proper configuration. However, even if three of the masters fail, the remaining NVG(s) are still operational and can have configuration changes made to them. Note that one master at a minimum has to be functional to be able to make configuration changes. If all masters have failed, the slaves will still be capable of processing SSL traffic.

Clustering Over Multiple Subnets

The SSL VPN software supports clustering over multiple subnets. If more than one VPN Gateway is required and the VPN Gateway you wish to join to the cluster is installed in a different subnet, the new NVG must be configured as a slave. Master NVGs cannot exist on different intranet subnets.
