Provide high availability of a secure gateway

To provide high availability of the Secure Gateway, it is recommended that you install two or more Secure Gateways and use a third-party redundant load balancer to manage access.

The load balancer will provide one address for end users. As requests arrive at the load balancer, they are redirected to an available Secure Gateway based on built-in weighting criteria. A basic round-robin load balancer can be used, but it may not detect whether a Secure Gateway is active or not.
