Used Ports

The following tables describe network ports that must be opened to ensure proper communication of components in the Veeam Agent management infrastructure.

Veeam Backup & Replication Connections

For information about network ports that must be opened to ensure proper communication of the backup server with backup infrastructure components, see the Used Ports section in the Veeam Backup & Replication User Guide.

For information about ports that must be opened to ensure communication of the backup server with Veeam Cloud Connect infrastructure components, see the Used Ports section in the Veeam Cloud Connect Guide.

In addition to general port requirements applicable to a Veeam backup server, the backup server used in the Veeam Agent management scenario must have the following ports opened:

Port

Notes

Veeam Backup Server

Veeam Agent Computer (Microsoft Windows)

TCP

6184+

Default port used for communication with the Veeam Agent for Microsoft Windows Service.

If port 6184 is already in use, Veeam Agent for Microsoft Windows Service tries to use the next port number in the allocated range (6184 to 6194). Once the service takes the next available port, it makes it the default port for all subsequent connections.

TCP
UDP

135,
137 to 139,
445,
6160,
11731

Default ports used for communication with the Veeam Installer Service.

Port 135 is used for WMI queries. WMI queries are mandatory to back up failover clusters and perform file-level restore and optional to provide faster Veeam Agent deployment.

Ports 137 to 139 are used by backup infrastructure components to communicate using NetBIOS.

Ports 137 to 139 and 445 are used during restore started from the Veeam Backup & Replication console.

Ports 6160 and 11731 are used to deploy Veeam Agent on the computer and to provide faster restore.

If the backup repository server role and the mount server role are assigned to different servers in your infrastructure, you must open ports described in the Mount Server Connections subsection of the Veeam Backup & Replication User Guide.

TCP

6162

Default port used by the Veeam Data Mover.

TCP

2500 to 3300

Default range of ports used for communication between Veeam Agent components during data transmission. For every TCP connection that a backup job uses, one port from this range is assigned.

Distribution Server

TCP
UDP

135,
137 to 139,
445,
6160,
11731

Ports on a Microsoft Windows server used for deploying the Distribution Server component.

Port 135 is optional. This port is used to provide faster Veeam Agent deployment.

Ports 137 to 139 are used by backup infrastructure components to communicate using NetBIOS.

Ports 6160 and 11731 are used by the Veeam Installer Service. These ports together with port 445 are mandatory to deploy the Distribution Server component.

TCP

49152 to 65535

Dynamic RPC port range. For more information, see this Microsoft KB article.

TCP

9380

Default port used for communication with the Veeam Distribution Service.

Backup Proxy

TCP

6211

[For storage snapshots support]  Port used for communication with the hardware VSS provider. For more information, see Storage Snapshots Support.

Distribution Server

Veeam Agent Computer (Microsoft Windows)

TCP

49152 to 65535

Dynamic RPC port range. For more information, see this Microsoft KB article.

The port range is required for communication with the Veeam Installer Service.

TCP
UDP

6160,
11731

Ports on the Veeam Agent computer used for deploying Veeam Agent.

Veeam Agent Computer (Linux)

TCP

22

Default port used to establish an SSH connection for the purpose of Veeam Agent packages transmission and deployment control.

Notes

Veeam Agent Computer (Microsoft Windows)

Veeam Backup Server

TCP

10005

Default port used by Veeam Agent for Microsoft Windows operating in the managed mode for communication with the Veeam Backup server.

Data between the Veeam Agent computer and backup repositories is transferred directly, bypassing Veeam backup servers.

Veeam Agent Computer (Microsoft Windows)

TCP

9395+, 6183+

Ports used locally on the Veeam Agent computer for communication between Veeam Agent components and Veeam Agent for Microsoft Windows Service.

If port 9395 or 6183 is already in use, Veeam Agent for Microsoft Windows Service will try to use the next port number.

Veeam Agent Computer (Linux, Unix, macOS)

Veeam Backup Server

TCP

10006

Default port used for communication with the Veeam Backup server.

Data between the Veeam Agent computer and backup repositories is transferred directly, bypassing Veeam backup servers.

Veeam Agent Computer (Linux, Unix, macOS)

TCP
