I am not aware of Citrix sessions being proxyable by HTTP proxies...
but maybe they have added CONNECT support in the client allowing the
client to abuse HTTP proxies.. This is not what HTTP proxies are
intended to be used for, but some find it a good idea for some
reason..

Is there any valid reason to Orange not supporting NAT or direct
access for non-HTTP protocols such as Citrix or other application
protocols? Or is the problem in how Internet clients should be able
to reach your Citrix server inside the proxy? If the latter then it
should be possible to solve this by providing a public NAT address or
port forwarder the Citrix clients can connect to from the Internet

Note: The HTTP proxy should be used for downloading the access
applet/setup if you are using the web version, but then the client
should talk directly to the Citrix server.
