Example: adding a node to a Firewall Cluster element

An example of adding a node to an existing Firewall Cluster element and configuring the interfaces.

Company A’s Firewall currently consists of two nodes. However, the load on the Firewall is exceptionally high, so the administrator has decided to add another node to ensure continuity of network services even when one of the nodes is offline. The administrator does the following:
  1. Adds a third node in the Firewall Cluster element’s properties.
  2. Defines the node-specific IP addresses for the NDI interfaces of the new node.
    • The cluster-level interface configuration does not need adjustments because it is shared by all nodes.
  3. Installs the new engine and performs the initial configuration.
  4. Refreshes the security policy of the Firewall Cluster.
