Trying to connect to a Citrix Presentation Server (installed on top of Windows Server 2003) from the outside using Access Essentials via web browser. I have ports 80, 443, 8080, 2598, and 1494 all forwarding to the Presentation Server. I can access the web interface, login, and see the options for Desktop and other programs that I can run via Citrix but when I try to connect it times out and says "No server available and this address". I have tried the different connection types and also added the url to Trusted Sites in IE. Am I missing a port maybe?
