Network firewalls can allow or block packets based on the destination address and port. If you are using a firewall in your deployment, Citrix Receiver for Windows must be able to communicate through the firewall with both the Web server and Citrix server.

Common Citrix Communication Ports

Source	Type	Port	Details
Citrix Receiver	TCP	80/443	Communication with StoreFront
ICA/HDX	TCP	1494	Access to applications and virtual desktops
ICA/HDX with Session Reliability	TCP	2598	Access to applications and virtual desktops
ICA/HDX over SSL	TCP	443	Access to applications and virtual desktops
ICA/HDX from HTML5 Receiver	TCP	8008	Access to applications and virtual desktops
ICA/HDX Audio over UDP	TCP	16500-16509	Port range for ICA/HDX audio
IMA	TCP	2512	Independent Management Architecture (IMA)
Management Console	TCP	2513	Citrix Management Consoles and *WCF services Note: For FMA based platforms 7.5 and later, port 2513 is NOT used.
Application/Desktop Request	TCP	80/8080/443	XML Service
STA	TCP	80/8080/443	Secure Ticketing Authority (embedded into XML Service)

Note

In XenApp 6.5 port 2513 is used by XenApp Command Remoting Services through WCF.

If the firewall is configured for Network Address Translation (NAT), you can use the Web Interface to define mappings from internal addresses to external addresses and ports. For example, if your XenApp or XenDesktop server is not configured with an alternate address, you can configure the Web Interface to provide an alternate address to Receiver. Citrix Receiver for Windows then connects to the server using the external address and port number. For more information, see the Web Interface documentation.
