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.

For the list of ports used by the backup server to communicate with backup repositories, see the Veeam Backup & Replication User Guide, section Used Ports.

vPower NFS Service

The vPower NFS Service is a Microsoft Windows service that runs on a Microsoft Windows machine and enables this machine to act as an NFS server. The vPower NFS Service is required to perform such operations as file-level restore and Instant Recovery.

Note

For the full list of ports required for Performing File-Level Restore, see the Veeam Backup & Replication User Guide, section Used Ports.

From	To	Protocol	Port	Notes
Nutanix AHV cluster	Microsoft Windows server with the mount server role running vPower NFS Service	TCP UDP	111	Used by the Port Mapper service.
TCP UDP	1058+ or 1063+	Used as default mount port. The number of port depends on where the vPower NFS Service is located: 1058+: If the vPower NFS Service is located on the backup server. 1063+: If the vPower NFS Service is located on a separate Microsoft Windows machine. If port 1058/1063 is occupied, the succeeding port numbers will be used.
TCP UDP	2049+	Used as NFS port. If port 2049 is occupied, the succeeding port numbers will be used.

Guest Processing Components

The following tables describe network ports that must be opened to ensure proper communication of the backup server and backup infrastructure components with the non-persistent runtime components deployed inside the VM guest OS for application-aware processing and indexing.

From	To	Protocol	Port	Notes
Backup server	VM guest OS (Linux)	TCP	22	Default SSH port used as a control channel.
	VM guest OS (Linux)	TCP	2500 to 3300	Default range of ports used as transmission channels for log shipping.
	Guest interaction proxy	TCP	6190	Used for communication with the guest interaction proxy.
		TCP	6290	Used as a control channel for communication with the guest interaction proxy.
		TCP	445	Port used as a transmission channel.
Guest interaction proxy	VM guest OS (Microsoft Windows)	TCP	445 135	Required to deploy the runtime coordination process on the VM guest OS.

During setup, Veeam Backup & Replication automatically creates a firewall rule for the runtime process. If you use firewall settings other than default ones or application-aware processing fails with the "RPC function call failed" error, you need to configure dynamic RPC ports. For more information on how to configure RPC dynamic port allocation to work with firewalls, see this Microsoft KB article.
