Bruno Yes, you need to use Citrix Secure Gateway. The purpose of CSG is to secure the connection using SSL and HTTPS, and thus uses port 443 and not 1494. You should find virtually every firewall has 443 open.

To my understanding, all the communication between the client workstation and Web Interface server occurs by default on port 80. Once the connection is established, to the internal Citrix server, it is using port 1494 at this time. Are major issue is that when a user is offsite at a client location, the client firewall usually has port 1494 blocked. Is there a better solution then always asking the client to open the port on there firewall? Or is Citrix Secure Access a better solution? Thanks for your help in advance.
