Abstract
Disclosed is a system and method for providing persistence in network access, by enhancing the likelihood that a gateway that is employed by a server array controller to send a client's message to a resource in another network outside of a local network behind the server array controller, is the same gateway employed by the resource for a responding message. In one embodiment, an outbound gateway is selected based on load-balanced gateways that have been enabled for automatic mapping of a source address to an available corresponding global Internet Protocol address. In another embodiment, multiple server array controllers are employed in a multi-active mode that enables multiple network address translation tables to be available in the event of a failover of one or more of the server array controllers.
