It is because Citrix is highly-protective of their intellectual property and refuses to allow 3rd party companies like Juniper to develop ICA proxy functionality. Otherwise we would have done it already. Citrix does offer a partner alliance but automatically denies entry to any of their competitors. We are investigating options on how to handle the proxy'ing of ICA traffic on iOS-based devices, but today ZanyTerp is correct that you will need to establish a Layer 3 VPN session via Junos Pulse prior to connecting to your Citrix XenApp/XenDesktop environment.
