We currently have a two-firewall cluster. We are working on getting a third member added to this cluster and I have it on my desk for configuration. We are required to have most of the set up done before it is racked and added to the network. This is so Cyber Security can do an assessment before it is added to our network.
What would be the best way to add this new firewall to the cluster?
-Configure as a local configuration with an IP on an interface that I can access
-Install firewall and confirm I can see it on the network
-Manually add it to the cluster (convert from local to cluster configuration?)
or is it possible to do a cluster setup before adding it to the network?
I have the option to do as much local setup as possible for the assessment and then do a follow up assessment after installation.
