Which port does a Citrix Administrator need to open for Cloud Connector to communicate with the internet?

• A. 80
• B. 3389
• C. 8080
• D. 443

Answer: (D)

Cloud Connectors communicate with Citrix Cloud over secure HTTPS. This requires outbound traffic on port 443, which is the standard TLS/SSL port for secure web services. The Cloud Connector initiates connections to Citrix Cloud from your network to receive updates, configuration, and policy information, so you only need outbound access and not inbound. The other ports aren’t used for this purpose: 80 is plain HTTP (not secure), 3389 is RDP for remote desktop access, and 8080 is another HTTP alternative not used by Cloud Connector to reach the internet. Opening port 443 outbound ensures the Cloud Connector can reliably communicate with Citrix Cloud.
