During installation, Veeam usually attempts to create local Windows Firewall rules automatically. veeam backup port
Veeam Backup & Replication is a powerful data protection platform, but its functionality depends entirely on correct network communication between components (Backup Server, Repository, Proxy, Gateway, and Hypervisor Hosts). Ports are the "plumbing" of this architecture. Misconfigured ports are the #1 cause of backup failures, slow performance, and security vulnerabilities. Overall, Veeam’s port requirements are well-documented but complex, especially in hardened or air-gapped environments. : The default port for communicating with the
Veeam Backup & Replication uses a specific set of network ports to coordinate communication between the backup server, proxies, repositories, and managed infrastructure. The most critical ports include , 445 , and 6160 for component deployment and management, alongside a dynamic data transmission range of TCP 2500–3300 .

Need a specific port list for your hypervisor (VMware/Hyper-V/Nutanix) or repository type? Let me know and I can provide the exact table.
: The default range for data transmission channels . For every parallel task in a job, one port from this range is assigned. Older installations (upgraded from versions prior to 10.0) may use the range 2500–5000 .
