Common Citrix® communication ports
As you are building your infrastructure, it's important to know what type of protocols will run across your network. Sometimes, system administrators separate devices with network routers, switches, and firewalls that can block the XenDesktop implementation from working. The following is a list of protocols that you should allow through the routers, switches, and firewalls. All the Citrix protocols can be found in CTX Article 101810 at http://support.citrix.com/article/CTX101810.
