About Network Access Control
The Network Access Control feature lets you control which IP addresses (IPv4 or IPv6) are allowed to access the appliance. This feature is available through the NetBackup Appliance Shell Menu as follows:
Main > Settings > Security > NetworkAccessControl
The available command options are AddIP, DeleteIP, and Show.
Appliance access is allowed through HTTPS for the NetBackup Appliance Web Console or rest APIs, and through SSH for the shell menu. To permit access to a specific appliance, add the necessary client IP addresses to the allowed list for that appliance. Any client IP addresses that are not included in the allowed list cannot access the appliance. Any interface level restrictions are managed separately and are also appliance-specific.
For high availability (HA) setups, you must configure the NetworkAccessControl options on both appliance nodes and the configurations must match.
If your appliance is configured as an Appliance Management Server (AMS) or is an agent for an AMS, make sure that you add those IP addresses to the allowed list. The AMS must include the IP addresses of the agents, and the agents must include the IP address of the AMS.
