Ports

This section covers typical Veeam Backup Enterprise Manager connections and default ports required for communication between Enterprise Manager components. The ports must be open on the target machine for inbound connections.

Note

For more information on ports specific for Veeam Backup & Replication infrastructure components, see the Ports section of the Veeam Backup & Replication User Guide.

Veeam Backup Enterprise Manager Connections

		TCP	49152 to 65535 (for Microsoft Windows 2008 and later)	Ports used by Enterprise Manager service to communicate with Active Directory. These ports are also used during restore through Veeam Self-Service File Restore Portal. This is a default dynamic port range. For more information, see Microsoft Support KB 832017.
	Veeam License Update Server	TCP	443	Default port used to automatically update license from the Veeam License Update Server over HTTPS. Veeam License Update Server endpoints: vbr.butler.veeam.com autolk.veeam.com
	Veeam License Update Server	TCP	80	Required for certificate validation when Enterprise Manager connects to Veeam License Update Server to check if the new license is available and download it. Certificate verification endpoints: .ss2.us .amazontrust.com Consider that certificate verification endpoints (CRL URLs and OCSP servers) are subject to change. The actual list of addresses can be found in the certificate itself.
Veeam Backup Enterprise Manager website (IIS extension)	Veeam Backup Enterprise Manager service	TCP	9394	Default port used by IIS extension to communicate with Veeam Backup Enterprise Manager. Can be customized during Veeam Backup Enterprise Manager installation. For more information, see Specify Service Ports.
Veeam Cloud Connect Portal website (IIS extension)	Veeam Backup Enterprise Manager service	TCP	9397	Default port used by IIS extension to communicate with Veeam Backup Enterprise Manager. This port value is built-in and cannot be customized during installation.
Browser	Veeam Backup Enterprise Manager website (IIS extension)	HTTP	9080	Default ports used to communicate with the website. Can be customized during Veeam Backup Enterprise Manager installation. For more information, see Specify Service Ports. When you work with Veeam Self-Service Backup Portal (accessed by the portal URL or from the native VMware Cloud Director environment) and vSphere Self-Service Backup Portal, your browser also communicates with the Veeam Backup Enterprise Manager website over this port.
	Veeam Backup Enterprise Manager website (IIS extension)	HTTPS	9443
	Veeam Cloud Connect Portal website (IIS extension)	HTTPS	6443	Default ports used to communicate with the website. Can be customized during Veeam Backup Enterprise Manager installation. For more information, see Specify Service Ports.
Veeam Backup Enterprise Manager REST API client and VMware vSphere Client plug-in	Veeam Backup Enterprise Manager REST API	HTTP	9399	Default ports used to communicate with Veeam Backup Enterprise Manager REST API. Can be customized during Veeam Backup Enterprise Manager installation. For more information, see Specify Service Ports.
	Veeam Backup Enterprise Manager REST API	HTTPS	9398
Veeam ONE Server (optional)	Veeam Backup Enterprise Manager server	TCP	Dynamically assigned ports	If you add the Veeam Backup Enterprise Manager server to the Veeam ONE monitoring scope, you must open ports required to gather data through WMI. For more information on enabling and disabling WMI traffic, see the Connecting to WMI Remotely with VBScript and Setting up a Remote WMI Connection articles of the Microsoft Windows Dev Center.

Note

Consider the following:

For communication between the Veeam Backup Enterprise Manager server and backup servers, Kerberos authentication is used by default.
During installation, Veeam Backup & Replication automatically creates firewall rules for default ports to allow communication for the application components.
For more information on Enterprise Manager network connectivity, refer to the Enterprise Manager article of the Veeam Backup and Replication Best Practices documentation.
