Used Ports

Make sure that you open ports listed below to enable proper work of Veeam Agent for Microsoft Windows.

From	To	Protocol	Port	Notes
Veeam Agent Computer	Veeam Backup Server	TCP	10001	Default port used by Veeam Agent for Microsoft Windows operating in the standalone 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	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 the default port number is already in use, Veeam Agent for Microsoft Windows Service will try to use the next port number.
	Veeam Update Notification Server (autolk.veeam.com)	TCP	443	Default port used to download information about available updates from the Veeam Update Notification Server over the Internet.
Communication with Veeam Backup & Replication Repositories
Veeam Agent Computer	Linux server performing the role of a backup repository	TCP	22	Port used as a control channel from the Veeam Agent computer to the target Linux host.
	Linux server performing the role of a backup repository	TCP	2500 to 3000	Default range of ports used as data transmission channels. For every TCP connection that a job uses, one port from this range is assigned. In case of more than 500 concurrent job tasks, open additional ports.
	Microsoft Windows server performing the role of a backup repository	TCP	49152 to 65535 (for Microsoft Windows 2008 and newer)	Dynamic RPC port range. For more information, see this Microsoft KB article.
		TCP	2500 to 3000	Default range of ports used as data transmission channels. For every TCP connection that a job uses, one port from this range is assigned. In case of more than 500 concurrent job tasks, open additional ports.
	Shared folder CIFS (SMB) share	TCP UDP	135, 137 to 139, 445	Ports used as a transmission channel from the Veeam Agent computer to the target CIFS (SMB) share.
	Gateway Microsoft Windows server	TCP UDP	135, 137 to 139, 445	If a CIFS (SMB) share is used as a backup repository and a Microsoft Windows server is selected as a gateway server for this CIFS share, these ports must be opened on the gateway Microsoft Windows server.
		TCP	49152 to 65535 (for Microsoft Windows 2008 and newer)	Dynamic RPC port range. For more information, see this Microsoft KB article.
		TCP	2500 to 3000	Default range of ports used as data transmission channels. For every TCP connection that a job uses, one port from this range is assigned. In case of more than 500 concurrent job tasks, open additional ports.
