Ports
Veeam Backup for Proxmox VE automatically creates firewall rules for the ports required to allow communication between the Proxmox VE server, workers and the backup server.
Workers
The following table describes network ports that must be open to ensure proper communication of workers with other backup infrastructure components.
From | To | Protocol | Port | Notes |
|---|---|---|---|---|
Worker | Proxmox VE server | TCP/HTTPS | 8006 | Used to communicate with the REST API service running on the Proxmox VE server. |
Proxmox VE server | SSH | 22 | Used to communicate with Proxmox VE server. | |
Backup server | TCP | 10006 | Used to communicate with the backup server. | |
Backup server | TCP | 19001 | Used to communicate with the backup server. | |
Veeam backup repository or gateway server | TCP | 2500-3300 | Default range of ports used as transmission channels for jobs and restore sessions. For each TCP connection that a job uses, one port from this range is assigned. | |
Rocky Linux repositories (mirrors.rockylinux.org, mirrors.fedoraproject.org, rockylinux.map.fastly.net) | TCP/HTTP(S) | 80 (443) | Used to get OS security updates and .NET Core package updates. The listed mirror URLs are used to get actual URLs that will be used to obtain updates. | |
