Firewall and Load Balancing Considerations

CAS Manager and the Connector require certain ports to be open to enable connections between the CAS Manager, Connector, Remote Workstations, as well as other components.

Ports and Component Connections

Component            Allow Port/Protocol Source/Destination Component Descriptions
Connector Inbound 443 TCP From PCoIP Clients and administrative web browsers. For users to negotiate connections to their remote workstations. For accessing the Management Interface for (legacy) management of CAS Manager.
Connector Outbound 443 TCP To CAM Service, PCoIP Cloud License Server and to SumoLogic. To sync AD information to the CAM service and call CAS Manager APIs related to negotiating PCoIP sessions. To verify license activation code during the Connector installation. For log aggregation for support purposes.
Connector Outbound 60443 TCP To remote workstations. Prepares PCoIP Agents for a new user session.
Connector Inbound 4172 TCP/UDP From PCoIP Clients. For PCoIP Sessions with users that are outside of the corporate network.
Connector Outbound 4172 TCP/UDP To remote workstations. For PCoIP Sessions with users that are outside of the corporate network.
Connector Outbound 636 TCP To Domain Controllers. To authenticate users, and query user and computer information.
Connector Outbound 1812 UDP (This port is configurable) To RADIUS Server. For authentication against RADIUS Server.
Connector Outbound 53 UDP To DNS. Domain name resolution.
PCoIP License Server Inbound 7070 TCP (This port is configurable) From remote workstations. For license activation and verification from PCoIP Agent if the PCoIP License Server is used instead of the Cloud License Server.

Port and Component Notes:

  • Port 443 TCP is not required if the PCoIP License Server is used in place of the Cloud License Server.
  • The RADIUS Server is optionally configured.
  • See the PCoIP License Server guide for changing port and configuring TLS encryption.
