Assurance IT Cloud Connect Guide > Requirements > Used Ports

The following table describes network ports that must be opened to ensure proper communication of components in the Veeam Cloud Connect infrastructure

From	To	Protocol	Port	Notes
Cloud gateway	SP backup server	TCP	6169	Port on the SP Veeam backup server used to listen to cloud commands from the tenant side. Tenant cloud commands are passed to the Veeam Cloud Connect Service via the cloud gateway.
		TCP	8190, 8191	Port on the SP Veeam backup server used by SP-side network redirector(s) to connect to the Remote Access Console and establish a Remote Desktop Connection to tenant.
		TCP	2500 to 5000	Port range used during transfer of the Veeam Availability Console agent from the SP Veeam backup server to the tenant backup server.
	SP backup repository	TCP	2500 to 5000	Default range of ports used as transmission channels for replication jobs. For every TCP connection that a job uses, one port from this range is assigned.
	SP backup proxy	TCP	2500 to 5000	Default range of ports used as transmission channels for replication jobs. For every TCP connection that a job uses, one port from this range is assigned.
	Provider-side network extension appliance	UDP	1195	Port used to establish secure VPN connection for network extension during partial site failover. If a tenant has several IP networks, additional odd ports should be opened starting from 1195 — one port per tenant's IP network. For example, a tenant Tenant1 replicates VMs that are connected to 3 IP networks. In the Veeam Cloud Connect infrastructure, the SP deployed a network extension appliance for Tenant1. In this case, the SP needs to open between the network extension appliance and the cloud gateway the following ports: 1195, 1197, 1199.
	WAN accelerator	TCP	6164	Controlling port for RPC calls.
		TCP	6165	Default port used for data transfer between WAN accelerators.
	Veeam Availability Console server	TCP	9999	Port on the Veeam Availability Console server used to communicate with the tenant backup server. Communication between tenant backup servers and Veeam Availability Console server goes through cloud gateways.
SP backup server	Cloud gateway	TCP	6168	Port on the cloud gateway used to listen for cloud commands from the Veeam Cloud Connect Service. The service cloud commands from the Veeam Cloud Connect Service are sent to set up, delete and check the status of data transport channels between tenants and the cloud repository.
	Provider-side network extension appliance	TCP	22	Port used for communication with the network extension appliance.
		ICMP	—	SP backup server needs access to the SP network extension appliance via ICMP.
SP backup repository (or gateway server)	Cloud gateway	TCP and UDP	6180	Port used for connections during the following operations: Creating a replica from a cloud backup Replica seeding from a cloud backup
Tenant backup server	Cloud gateway	TCP and UDP	6180	Port on the cloud gateway used to transport VM data from the tenant side to the SP side (UDP is used only during partial failover of a cloud replica).
	Tenant-side network extension appliance	TCP	22	Port used for communication with the network extension appliance.
	Certificate Revocation Lists	TCP	80 or 443 (most popular)	Tenant backup server needs access to CRLs (Certificate Revocation Lists) of the CA (Certification Authority) who issued a certificate to the SP. Generally, information about CRL locations can be found on the CA website.
Backup server	Veeam Update Notification Server (dev.veeam.com)	TCP	80	Default port used to download information about available updates from the Veeam Update Notification Server over the Internet.
	Veeam License Update Server (autolk.veeam.com)	TCP	443	Default port used for license auto-update.
	Backup server	TCP	10003	Port used for communication with the Veeam Backup Service (locally on the backup server).
Provider-side network extension appliance	Cloud gateway	UDP	1195	Port used to establish secure VPN connection for network extension during partial site failover. If a tenant has several IP networks, additional odd ports should be opened starting from 1195 — one port per tenant's IP network. For example, a tenant Tenant1 replicates VMs that are connected to 3 IP networks. In the Veeam Cloud Connect infrastructure, the SP deployed a network extension appliance for Tenant1. In this case, the SP needs to open between the network extension appliance and the cloud gateway the following ports: 1195, 1197, 1199.
Tenant-side network extension appliance	Cloud gateway	TCP and UDP	6180	Port used to carry tenant VM traffic from the tenant network extension appliance to the SP network extension appliance through the cloud gateway.
Tenant backup proxy (VMware vSphere) or Hyper-V server/off-host backup proxy (Microsoft Hyper-V)	Cloud gateway	TCP and UDP	6180	Port used for VM data transport to the cloud repository by backup jobs.
Tenant backup repository (Microsoft Windows server/ Linux server/ gateway (for CIFS share)	Cloud gateway	TCP and UDP	6180	Port used for VM data transport to the cloud repository by backup copy jobs.
Remote Access Console (SP LAN)	SP backup server	TCP	8191	Port used for communication with the Veeam Cloud Connect Service and SP-side network redirector(s).
		TCP	9392	Port used for communication with the Veeam Backup Service.
		TCP	10003	Port used for communication with the Veeam Backup Service.
Remote Access Console (Internet)	Cloud gateway	TCP	6180	Default port used for communication with the SP Veeam Cloud Connect Service and SP-side network redirector(s).
	Certificate Revocation Lists	TCP	80 or 443 (most popular)	Remote Access Console needs access to CRLs (Certificate Revocation Lists) of the CA (Certification Authority) who issued a certificate to the SP. Generally, information about CRL locations can be found on the CA website.
Tenant desktop computer or portable device	Veeam Cloud Connect Portal	TCP	6443	Port used for accessing Veeam Cloud Connect Portal by tenants. Veeam Cloud Connect Portal is installed on the SP Veeam Backup Enterprise Manager server as an optional component. It should be published on the internet by the SP administrator.
