Agents installed on the managed machines (end-user machines) need to have access to the following ports (inbound and outbound):
- Ports 443 and 8443 are used for agent registration, data center selection, user authorization, certificate download, Web Restore and Backup management console access.
- Ports 7770-7800 are used for agent communication with Management server (backup plans creation and applying, status reports, activity logging, etc.).
- Port 44445 is used backup read-write operations.
