I've got an InstaGate PRO configured as a proxy server on my end that I have full control over. There's an application hosted by another company that runs on a MetaFrame server, I don't know what flavor or version. I have no control over the MetaFrame server and I'm not a Citrix admin.
A user on my end tries to launch a hosted application from a web page. The Citrix client starts and the user is prompted to authenticate to the proxy server. I've verified that proxy server correctly checks in with a RADIUS server on my network and authenticates the user.
The connection fails with the message "Cannot connect to the Citrix MetaFrame server. Proxy connection failed: The configured proxy server refused to establish a connection"
I've verified that port 1494 is on the proxy server's allowed ports list. If I remove 1494 I get the same error. I haven't been able to confirm that they are using the default port (is this discoverable from my end?).
