This article provides an overview of common ports that are used by Citrix Hypervisor components and must be considered as part of networking architecture, especially if communication traffic traverses network components such as firewalls or proxy servers where ports must be opened to ensure communication flow.

Not all ports need to be open, depending on your deployment and requirements.
