Communication channels
While XenDesktop/XenApp uses a large number of ports to communicate between components, the most common ones are:
- Ports 80/443 used by Receiver to connect to StoreFront
- Port 1494 when the ICA/HDX protocol starts
- Port 2598 for Session reliability (if enabled)
- Ports 80/8080/443 for the XML service and 2513 for the Citrix Management console
The following table illustrates the complete list of ports used by XenApp/XenDesktop 7.5 and later:
