SaaS Connector Management
Ensure that the following ports are open to allow communication between the Cohesity-deployed SaaS Connector(s) and Cohesity DataProtect as a Service:
| Source | Destination | Port | Protocol | Purpose |
|---|---|---|---|---|
| SaaS Connector |
|
443 | TCP | Connection used for control path. |
| SaaS Connector | *.awsglobalaccelerator.com | 443 | TCP | Connection used for control path. |
| SaaS Connector |
|
443 | TCP | Used to send telemetry data. |
| SaaS Connector | *.cloudfront.net | 443 | TCP | To download upgrade packages. |
| SaaS Connector | 8.8.8.8 or internal DNS | 53 | TCP, UDP | Host resolution. |
| SaaS Connector | time.google.com or internal NTP | 123, 323 | UDP |
Incoming NTP requests are detected by port 123. Chrony is the default implementation of NTP used by recent versions of CentOS and RHEL. Open port 323 if you want to use the Chronyc tool to monitor the synchronization status of Chrony and make changes if necessary. |
| SaaS Connector | rt.cohesity.com | 22 or 443 | TCP | The Cohesity Support Channel uses Secure Shell (SSH) and listens through port 22 or 443. Port 22 is used by default and can be updated to 443 using the Cohesity CLI. For more information, see Manage the Support Channel. |
