Follow the instructions mentioned in Step 8. Verify your Configuration and Change the Password in the Barracuda Load Balancer ADC Deployment and Quick Start Guide for Amazon Web Services article to verify your configuration and change the password on both of the deployed Barracuda Load Balancer ADC instances.

Step 5. Cluster the Deployed Barracuda Load Balancer ADC Instances

Follow the instructions mentioned in Step 5: Cluster the Deployed Barracuda Load Balancer ADC Instances in the Clustering the Barracuda Load Balancer ADC Instances in the Same Availability Zone article to deploy the instances.

Step 6. Configure the Service(s) on the Barracuda Load Balancer ADC

If you have deployed the Barracuda Load Balancer ADC instance with two interfaces (i.e., mgmt (eth0) and ge-1-1 (eth1)), create the service by following the steps mentioned below:
