I have Citrix WebInterface 5.4 (WI) and Secure Gateway 3.3.1 (CSG) running on Windows 2008 R2 and NOT a member of my XenApp 6.5 farm. The CSG is working internally over SSL, but not externally over the Internet. When I try to launch a published app remotely, I get the following error after logging-in:
Unable to launch your application. Contact your help desk with the following information: there is no Citrix XenApp server configured on the specified address
Our firewall only allows ingress SSL/443 and the FQDN is NAT'ed 1:1 and resolvable locally on the CSG server.
