If my sonicwall NSA 2400 was to ever die I want it to automatically failover to the old PRO 2040 it replaced. Is this possible with two different generations of Sonicwall? If so, what things do I need to take into consideration? My Google-fu fails me so far. Thanks!
For a failover scenario, the two devices should be of the same model and running identical firmware. Also, the two devices are to be registered with Sonicwall as a Failover pair.
