Morro Data devices use the following outbound ports:
| Port | Service | Required | Purpose |
| 443 (TCP) | HTTPS | Yes | Used to communicate with the Morro Cloud server and Cloud Storage and Services Providers, like Wasabi and Amazon S3. Also required for proxy support (experimental). |
| 123 (UDP) | NTP | Yes | Network Time Protocol server for time synchronization. Only needed if NTP server returned from DHCP is external. |
| 22 (TCP) | SSH | No | Secure Shell access to the device for support. See additional notes below. |
| 389 (UDP+TCP) | LDAP | No | Required for LDAP authentication support. |
| 636 (UDP+TCP) | LDAP | No | Required for LDAP over SSL authentication support. |
| 53 (UDP+TCP) | DNS | Yes | Not required if DNS server is internal. |
When opening a port for SSH access, set the source IP to the IP address of the CacheDrive. Destination can be set to "Any", but for additional security, use the value "techsupport.morrossystem.com".
