Ports

Veeam Backup for Nutanix AHV automatically creates firewall rules for the ports required to allow communication between the Nutanix AHV backup appliance, workers and the backup server.

Important

Some Linux distributions require manual configuration of firewall rules. For more information, see this Veeam KB article.
