Custom ICA config question


Some of our users connect to a citrix desktop using a custom ICA connection in program neighborhood. The connection options are all default EXCEPT that the server they are connecting to requires 128 bit encryption for the session. I created a terminal services resource profile using the custom ICA option. I downloaded and modified the default ICA file as described in the documentation. I replaced the <CITRIX_CLIENT_NAME>, <APPDATA> and <TARGET_SERVER> areas in the default ICA file and added the sections that defined 128 bit encryption for the connection). I tested the file by manually launching it from a PC with the Citrix client installed and it worked fine. I then uploaded it to the IVE and entered a resource policy to open 1494 and 2598 to the IP specified in the ICA file. When I login to the SSL VPN with a test user and click the new bookmark, the Juniper Citrix Client launches and goes from 'initalizing' to 'connection in progress'. I then get an error message saying "there is no Citrix server configured on the specified address". If the connection works when I launch the ICA file from my desktop, but does not when I try to launch it through the SSL VPN. Is this becuase of the encryption? I have seen another post for a similar issue, and it was related to the Juniper Citrix client not being able to use encryption. Has anyone seen this issue before?

Re: Custom ICA config question

For Citrix 128 bits encryption to work properly, you need to be at least on the following release:

IVE OS 6.2R6, 6.3R5, 6.4R2 or 6. 5R1 or a higher maintenance release.

Check for the following in Release Notes:

The Juniper Citrix Listed Applications functionality now supports the Encryption settings that are configured on a Citrix Metaframe Presentation server. (418081)

Re: Custom ICA config question

I am currently running 6.4 R2. It still doesnt seem to work. Can you tell me if the lines I added to the custom ICA file are correct? As I said, the file launches fine when I launch with the Citrix client, but when I try with the Juniper Citrix Services Client, it fails.

Any ideas?
