Network ports 编辑

The following table lists the default network ports used by XenApp and XenDesktop Delivery Controllers, Windows VDAs, Director, and Citrix License Server. When Citrix components are installed, the operating system’s host firewall is also updated, by default, to match these default network ports.

For an overview of communication ports used in other Citrix technologies and components, see Communication Ports Used by Citrix Technologies.

You may need this port information:

For regulatory compliance purposes.
If there is a network firewall between these components and other Citrix products or components, so you can configure that firewall appropriately.
If you use a third-party host firewall, such as one provided with an anti-malware package, rather than the operating system’s host firewall.
If you alter the configuration of the host firewall on these components (usually Windows Firewall Service).
If you reconfigure any features of these components to use a different port or port range, and then want to disable or block ports that are not used in your configuration. Refer to the documentation for the component for details.

For port information about other components such as StoreFront and Provisioning Services, see the component’s current “System requirements” article.

The table lists only incoming ports; outgoing ports are usually determined by the operating system and use unrelated numbers. Information for outgoing ports is not normally needed for the purposes listed above.

Some of these ports are registered with the Internet Assigned Numbers Authority (IANA). Details about these assignments are available at https://www.iana.org/assignments/port-numbers; however, the descriptive information held by IANA does not always reflect today’s usage.

Additionally, the operating system on the VDA and Delivery Controller will require incoming ports for its own use. See the Microsoft Windows documentation for details.

VDA, Delivery Controller, and Director

Component	Usage	Protocol	Default incoming port	Notes
VDA	ICA/HDX	TCP, UDP	1494	EDT protocol requires 1494 to be open for UDP. See ICA policy settings.
VDA	ICA/HDX with Session Reliability	TCP, UDP	2598	EDT protocol requires 2598 to be open for UDP. If multi-stream and multi-port are enabled, the administrator defines the port numbers for the additional three streams. See ICA policy settings.
VDA	ICA/HDX over TLS/DTLS	TCP, UDP	443	All Citrix Receivers
VDA	ICA/HDX over WebSocket	TCP	8008	Citrix Receiver for HTML5, and Citrix Receiver for Chrome 1.6 and earlier only
VDA	ICA/HDX audio over UDP Real-time Transport	UDP	16500..16509
VDA	ICA/Universal Print Server	TCP	7229	Used by the Universal Print Server print data stream CGP (Common Gateway Protocol) listener.
VDA	ICA/Universal Print Server	TCP	8080	Used by the Universal Print Server listener for incoming HTTP/SOAP requests.
VDA	Wake On LAN	UDP	9	Remote PC Access power management
VDA	Wake Up Proxy	TCP	135	Remote PC Access power management
VDA	Delivery Controller	TCP	80
Delivery Controller	VDA, StoreFront, Director, Studio	TCP	80
Delivery Controller	StoreFront, Director, Studio over TLS	TCP	443
Delivery Controller	Delivery Controller, VDA	TCP	89	Local Host Cache (This use of port 89 might change in future releases.)
Delivery Controller	Orchestration	TCP	9095	Orchestration
Director	Delivery Controller	TCP	80, 443
