Citrix XenApp and XenDesktop
More and more organizations are using the BIG-IP system to secure, optimize, and scale their Citrix XenApp/XenDesktop deployments. Since the days when these applications were known as MetaFrame, F5 has been testing and tuning the BIG-IP system for Citrix implementations, and detailing the procedures first in our deployment guides, and now in our iApp templates for Citrix as well. Not only can the BIG-IP system act as a replacement for the Citrix Web Interface servers, but it can securely proxy Citrix ICA traffic using TCP optimization profiles which increase overall network performance for your application. You also have the option to configure the BIG-IP APM with smart card authentication or with two factor authentication using RSA SecurID. The following simple, logical configuration example shows one of the ways you can configure the BIG-IP system for Citrix Xen deployments. In this example, the BIG-IP APM Dynamic Presentation Webtop functionality is used to eliminate the need for the Citrix Web Interface StoreFront server tier. With BIG-IP APM, a front-end virtual server is created to provide security, compliance and control. The iApp template configures the APM using Secure ICA Proxy mode. In secure ICA proxy mode, no F5 BIG-IP APM client is required for network access. The BIG-IP system uses SSL on the public (non-secure) network and ICA to the servers on local (secure) network. See the deployment guide for more information. Seehttps://devcentral.f5.com/s/articles/citrix-vdi-iapp-templatefor information on using the iApp template to configure the BIG-IP system for Citrix. See https://f5.com/solutions/deployment-guidesto find the appropriate deployment guide for quickly and accurately configuring the BIG-IP system for Citrix XenApp/XenDesktop. If you have any feedback on these or other F5 guides or iApp templates, leave it in the comment section below or email us at solutionsfeedback@f5.com. We use your feedback to help shape our new iApps and deployment guides.

In 5 Minutes or Less Video - BIG-IP APM & Citrix XenApp
Watch how F5 customers can now simply use BIG-IP Access Policy Manager or BIG-IP Edge Gateway to consolidate access control in a central location, keeping infrastructure administration concerns to a minimum. With BIG-IP solutions, customers enjoy the flexibility and scalability needed to extend Citrix applications to both local and remote users without changing local XenApp deployments or requiring STA to provide secure remote access to applications. Highlights of deploying Citrix and F5 technologies together include: Reduced Management Time and OpEx – By simplifying and centralizing local and remote access authentication, BIG-IP solutions eliminate the need for customers to add separate Citrix STA infrastructure or make changes to existing Web Interface servers, resulting in an environment that is less expensive to deploy and requires less time to manage. Simplified Configuration and Deployment – With BIG-IP solutions, administrators can support users of Citrix applications with fewer devices, configure deployments to support flexible access models, and easily scale the environment. This fully integrated functionality makes it quick and easy for customers to set up and deploy local and remote access capabilities for Citrix applications, keeping users productive. Centralized and Comprehensive Access Control – Unlike the separate Citrix products required to adequately support applications for remote users, BIG-IP solutions provide centralized application access control and use a single access policy to support all types of users securely, so IT teams can be confident that application access is aligned with the organizations’ specific business priorities and security policies. &amp;amp;amplt;/p&amp;amp;ampgt;

Citrix XenApp 5.0 Implementation Tips
I recently had the pleasure of working on a Citrix 5.0 implementation and I wanted to share a few things that I learned during that setup. As many of you know, there are two deployment guides that have been made available by F5 Networks in regards to setting up Citrix Presentation Server 4.5 in TMOS versions 9.x and 10.x. They are excellent guides and the best thing about them is that you can utilize those guides to assist you in deploying Citrix XenApp 5.0, with a few exceptions of course. Those exceptions are what I will be covering in this tech tip. Both of the previously mentioned deployment guides discuss editing files on the Citrix farms Web Interface servers so that it looks for the client IP address in the X-Forwarded-For HTTP header. Otherwise, every connection will appear to be originating from the BIG-IP LTM and not from its true IP. After reading both guides and looking at my current environment I was dismayed to find that the files and locations mentioned were no longer valid. I then turned to my top three resources on the web in the search for an answer: AskF5, DevCentral and Google. I struck out on the first two (which seldom happens) but my Google search did turn up some interesting results on the Citrix Forums. I finally found some code posted by Sam Jacobs back in August 2009 that modifies the way the Citrix farm looks up the client IP address. His method allows for the use of the X-Forwarded-For header. The first file that you will want to find and edit is the Include.java file. You will want to locate and change this file on every Web Interface XenApp server in the farm. Speaking from experience, save a copy of the original file to a safe location such as your desktop or flash drive. DO NOT copy the file and rename the original to Include.old and leave it on the server. It may sound crazy, but doing that will not work. I’m not a programmer, so I cannot tell you why that will not work, but I can tell you I know for a fact it will not. That being said, here is the file path for the Include.java file: “\Inetpub\wwwroot\Citrix\XenApp\app_code\PagesJava\com\citrix\wi\pageutils\Include.java” Now that you have found the file, open it up with a text editor (I use Textpad) and find the Java routine named “getClientAddress”. Replace the code for that routine with the code listed below. public static String getClientAddress(WIContext wiContext) { String ageClientAddress = AGEUtilities.getAGEClientIPAddress(wiContext); String userIPAddress = wiContext.getWebAbstraction().getRequestHeader("X-FORWARDED-FOR"); if (userIPAddress == null) { userIPAddress = wiContext.getWebAbstraction().getUserHostAddress(); } return (ageClientAddress != null ? ageClientAddress : userIPAddress); } Save the file and wash/rinse/repeat this step on every Web Interface server in the farm. The next thing that you will want to do is to modify the login page so that it displays the client IP address being obtained from the X-Forwarded-For header. The file you will want to edit is called “loginView.ascx” and can be found in the following file path on your Web Interface Servers: ”\inetpub\wwwroot\Citrix\XenApp\app_data\include\loginView.ascx” The code you will want to add is: Client IP: <%= com.citrix.wi.pageutils.Include.getClientAddress(wiContext) %> I added the code directly below the LoginPageControl viewControl line and it works well for me. Save the file and repeat this step on every Web Interface server in the farm and reboot each Web Interface Server after you are done. That’s it! Well, you do have to complete the other setup steps listed in the deployment guide that you are using, but after that your farm will be ready for business! I am aiming to develop some custom monitors for the Web Interface Server and for the XML Broker Servers over the next few weeks. Once I have those done I will put them out in the forums for the community enjoy. -naladar
