xenapp 6.5 enviro. Netscaler VPX (5). Have entrust root, chain, and server certificates installed, linked, and verified. can connect locally through the netscaler virtual server without issue (logging into the virtual server from the LAN). Login, can see and access published desktop as well as published apps. When accessing through the external address though, i can log in and get all the way to the point of opening the desktop or apps and receive the error: "Unable to launch your application, cannot connect to Citrix Xenapp server. Can't assign requested address". SSL is showing valid from the remote computer.
The Netscaler is setup on the LAN side of my firewall, i have not moved it to the DMZ yet so LDAP and Citrix servers are all local. ports opened on firewall pointing to the virtual server only are 80,443,8080,2598,546-547,as well as 1494-1604 (this span will be corrected later).
