Citrix Virtual Apps and Desktops

Network ports

Complete network port information is provided in Communication Ports Used by Citrix Technologies.

When Citrix components are installed, the operating system’s host firewall is also updated, by default, to match the default network ports.

You might need port information:

  • For regulatory compliance.
  • If there is a network firewall between the Citrix Virtual Apps and Desktops 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 component features to use a different port or port range, and then want to disable or block ports that aren’t used in your configuration.

Some of the ports are registered with the Internet Assigned Numbers Authority (IANA). Details about these assignments are available at However, the descriptive information held by IANA does not always reflect today’s usage.

Also, the operating systems on the VDA and Delivery Controller require incoming ports for their own use. See the Microsoft Windows documentation for details.
