Citrix just posted an updated version of the PDF that describes the communication ports used by Citrix technologies. It’s a good reference document when talking about communications and for example which ports to open on a firewall in order to get proper communication between different technologies.
The introduction from the PDF:
This document provides an overview of ports that are used by Citrix components and must be considered as part of Virtual Computing architecture, especially if communication traffic traverses network components such as firewalls or proxy servers, where ports must be opened to ensure communication flow.
The PDF can be downloaded here.
