Ports

This section describes incoming connections for different components in the backup infrastructure. The first part describes ports that must be opened on the core backup infrastructure components. These ports allow basic operations for data protection such as backup and replication. The second part describes ports required for different features.

On backup infrastructure components, Veeam Backup & Replication automatically creates firewall rules for the required ports on Microsoft Windows-based machines. If you are using a third-party firewall, these rules must be created manually. These rules allow components to communicate with each other. You can find the full list of the ports for standard installations in this section.

Considerations

  • Ports described for the core backup infrastructure components are considered basic ports that must be opened whenever these components are used for any data protection tasks.
  • If a backup infrastructure component performs multiple roles (for example, acts as both a backup proxy and a repository), make sure all required ports for each role are opened.
  • Some Linux distributions also require firewall and security rules to be created manually. For details, see this Veeam KB article.
  • If you use an HTTP/HTTPS proxy server to access the Internet, make sure that WinHTTP settings are properly configured on Microsoft Windows machines with Veeam backup infrastructure components. For information on how to configure WinHTTP settings, see Microsoft Docs.
  • Tenants cannot access Veeam Cloud Connect infrastructure components through HTTP/HTTPS proxy servers. For information on supported protocols for Veeam Cloud Connect, see the Ports section in the Veeam Cloud Connect Guide.
