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.

Backup Appliance

The following table describes network ports that must be opened to ensure proper communication of the Nutanix AHV backup appliance with other backup infrastructure components.

From	To	Protocol	Port	Notes
Workstation web browser	Nutanix AHV backup appliance	TCP/HTTPS	443	Used to access the Nutanix AHV backup appliance web console.
Nutanix AHV backup appliance	Nutanix REST API	TCP/HTTPS	9440	Used to communicate with Nutanix AHV REST API.
	Backup server	TCP	10006	Used to connect to Veeam Backup & Replication.

Backup Server

The following table describes network ports that must be opened to ensure proper communication of the backup server with other backup infrastructure components.

From	To	Protocol	Port	Notes
Veeam Backup & Replication console and Veeam ONE server	Backup server	TCP/HTTPS	8543	Used to communicate with the Platform Service REST API.
FLR helper appliance	Backup server	TCP	2500	Used to connect to the backup server during file-level restore.
Mount Service	Backup server	TCP	9401	Used to connect to the backup server during file-level restore.
Backup server	FLR helper appliance	TCP	22 2500	Used to connect to the helper appliance during file-level restore. For the full list of ports used for connections to the FLR helper appliance, see the Veeam Backup & Replication User Guide, section Used Ports.
	Backup server	TCP/HTTPS	6172	Used by the AHV Platform Service to enable communication with the Veeam Backup & Replication database.
	Nutanix AHV cluster	TCP/HTTPS	9440	Used by the AHV Platform Service to connect to an Nutanix AHV cluster.
	Nutanix AHV backup appliance	TCP/HTTPS	443	Used by the AHV Platform Service to connect to Nutanix AHV backup appliance.

Note

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.
