I have a mixed xpe, fp3, fp4 Metaframe farm running on 2000 and 2003 servers. We have a internal network on a 10.1.x.x. My Web Interface works internally with no problems. But no one can access the applications from the outside, they can access the webinterface, but when launching a application it dies in the connection stage, saying No Citrix Metaframe server exists on the specified address. We have a 2003 server running IIS that has the web portal installed on it at 10.1.0.191, our firewall guy has published a external address 18.104.22.168 to our internal web portal server, including port forwarding of 80, 443, and 1494. I rebuilt the 191 server without presentation server installed and just IIS and the webconsole from a FP4 disk. I’ve saved the ICA file on the desktop of a remote PC and its showing the internal address of the published applications server in the connection information. How do I change the ICA file to give the external ip address?? If I manually change the ip in the file it launch's the application correctly.
