Citrix ICA Browser Access
Purpose:This document will go over the steps necessary to allow ICA browsing over TCP in order to access published applications, and applications sets, residing on a Citrix Metaframe Server Farm through the Microsoft ISA server. This will only work on systems running Metaframe 1.8 with FR1/SP2 or later, as that is the version where Citrix has added the additional functionality of TCP based ICA browsing. Prior to this release, you could only access a Metaframe Server Farm by utilizing UDP port 1604, and opening up all high ports on the server – which is clearly not recommended. Steps required:
Notes:In order to utilize ICA browsing over TCP, an additional port is needed by the Metaframe server. This port defaults to port 80, which will have to be changed on most ISA server installations. I use port 88 for my installs, but you are free to choose any available port for your install. Details of configuring the port on the Metaframe server will be discussed later, but this document will assume port 88 for ICA browse traffic. Details:
That should do it (at least that is what I did NOTE: Standard disclaimer applies. I’m not responsible for ANYTHING! I wish you luck, and will help if I can – but that’s it. Backup your systems, etc. before attempting anything. Verify security yourself – do not leave it for others! |
