  2. In the wizard, enter the IP address of the client or server that will connect to the database and click Add IP, then click Next. This will add the IP address to the list of IP addresses that are allowed network access to the cluster. The allow list is found on the Security page in the web console. For more information, see Network Security.

    If the IP address is already present in the allow list, just click Next.
