Step D: Configure Ports on the Firewall - AWS Elemental Delta

Step D: Configure Ports on the Firewall

You can leave the node firewall enabled or disabled. The installer configures each node's firewall for the ports that must be open for traffic to and from each node. If you plan to enable the firewall, you can open more ports for any reason.

For assistance opening ports or starting the firewall, see Opening Ports on the Firewall.


Whether the individual node firewalls are enabled or not, we recommend that the cluster always be installed behind a customer firewall on a private network.
