Step 3: Cluster’s pre-shared key and data encryption
If a cluster is being created
To secure the connection between members of the cluster, you will need to define a pre-shared key.
This key will only be used by firewalls that are joining the cluster for the first time.
Define a password/pre-shared key for your cluster.
Confirm the password/pre-shared key that you have just entered in the previous field.
|Mandatory password strength||
This field indicates your password’s level of security: “Very Weak”, “Weak”, “Medium”, “Good” or “Excellent”. You are strongly advised to use uppercase letters and special characters.
Communication between firewalls in the high availability cluster
|Encrypt communication between firewalls||
By default, communication between the firewalls is not encrypted, based on the principle that the link used by high availability is a dedicated link.
In some architectures, the high availability link is not dedicated, and if you wish to prevent inter-cluster communications from being read, they can be encrypted (in AES, for example).
If a cluster exists
|IP address of the firewall to contact||
Enter the IP address that you had defined in the wizard during the creation of the cluster (IP address of the main or secondary link).
Enter the password/pre-shared key that you had defined in the wizard during the creation of the cluster.
This icon allows you to view the password in plaintext to check that it is correct.
