Network configuration
The NetBackup instances need access to the public Internet for the product to function. If you are deploying NetBackup components in an existing VPC ensure that the subnet used to deploy the NetBackup instances has outbound access to the Internet, either through an internet gateway or a NAT gateway.
If you do not have a properly configured VPC available, you can choose to create a new one during the deployment. The VPC will be created with a public and a private subnet. The NetBackup primary server will be deployed in the public subnet so that you can access the NetBackup UI from a machine outside the VPC. NetBackup Media servers can be deployed in the private subnet for greater security.
