Ports

As Microsoft Azure Plug-in for Veeam Backup & Replication is installed on the same machine where Veeam Backup & Replication runs, it uses the same ports as those described in the Veeam Backup & Replication User Guide, section Ports. In addition, Microsoft Azure Plug-in for Veeam Backup & Replication also uses ports listed in the following table.

Tip

To allow inbound access to an Azure service, you can use the IP address, DNS name or virtual network service tag of the service. If you want to use an IP address, you can download a .JSON file with the full list of Azure IP ranges and service tags from the Microsoft Download Center.

		TCP	1433, 11000-11999	Required to connect to Azure SQL Managed Instances using private endpoints. Note: The usage of the specified TCP ports depends on the networking settings of SQL Servers. If the Redirect option is selected, port 1433 is used to establish only the first connection. If the Proxy option is selected, port 1433 is used to establish all connections by default. For more information on networking settings of SQL Servers, see Microsoft Docs.
