Used Ports

On backup infrastructure components, Veeam Backup & Replication automatically creates firewall rules for the required ports. These rules allow communication between the components.

Used Ports Important!

Some Linux distributions require firewall and/or security rules to be created manually. For details, see this Veeam KB article.
