Ports

NOTE

The following tables describe network ports that must be opened to ensure proper communication of Veeam Agent operating in the standalone mode with other infrastructure components.

To learn about ports required to enable proper work of Veeam Agent for Microsoft Windows managed by Veeam Backup & Replication, see the Ports section in the Veeam Agent Management Guide.

Ports IMPORTANT

The list of ports required for computers booted from the Veeam Recovery Media is the same as the list of ports required for Veeam Agent computers.

Communication Between Veeam Agent Components

The following table describes network ports that must be opened to enable proper communication between Veeam Agent for Microsoft Windows components.

From	To	Protocol	Port	Notes
Veeam Agent Computer	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.

Communication with Veeam Backup & Replication Repositories

The following table describes network ports that must be opened to ensure proper communication with Veeam backup repositories.

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.
	Linux server performing the role of a backup repository	TCP	2500 to 3300	Default range of ports used as data transmission channels. For every TCP connection that a job uses, one port from this range is assigned.
	Microsoft Windows server performing the role of a backup repository	TCP	49152-65535	Dynamic RPC port range. For more information, see Microsoft documentation.
		TCP	2500 to 3300	Default range of ports used as data transmission channels. For every TCP connection that a job uses, one port from this range is assigned.
	Shared folder SMB (CIFS) share	TCP UDP	137 to 139, 443, 445	Ports used as a transmission channel from the Veeam Agent computer to the target SMB (CIFS) share. Ports 137 to 139 are used by backup infrastructure components to communicate using NetBIOS. Port 443 is used to connect the target SMB (CIFS) share over QUIC. For more information, see Microsoft documentation.
	Gateway Microsoft Windows server	TCP UDP	137 to 139, 445	If an SMB (CIFS) 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. Ports 137 to 139 are used by backup infrastructure components to communicate using NetBIOS.
		TCP	49152-65535	Dynamic RPC port range. For more information, see Microsoft documentation.
		TCP	2500 to 3300	Default range of ports used as data transmission channels. For every TCP connection that a job uses, one port from this range is assigned.

Communication with Veeam Cloud Connect Repositories

The following table describes network ports that must be opened to ensure proper communication with Veeam Cloud Connect repositories.

From	To	Protocol	Port	Notes
Veeam Agent Computer	Cloud gateway	TCP	6180	Port on the cloud gateway used to transport Veeam Agent data to the Veeam Cloud Connect repository.
Certificate Revocation Lists	TCP	80 or 443 (most popular)	Veeam Agent computer needs access to CRLs (Certificate Revocation Lists) of the CA (Certification Authority) who issued a certificate to the Veeam Cloud Connect service provider. Generally, information about CRL locations can be found on the CA website.
