A Common Misconception About Virtual IP Configuration

Tuesday, 02 May 2006 by Michel Roth

This article was written to clarify one major aspect of enabling Virtual IP on a Citrix Presentation Server 4.0 server � that Virtual IP is enabled for ALL published applications on a server with Virtual IP enabled. Any application published on Citrix Presentation Server 4.0 Enterprise Edition that has Virtual IP enabled will consume a Virtual IP address regardless of whether it is listed in the �Monitor the following processes list� or not.

So for example, if you have a telephony (or �CTI�) application that requires a Virtual IP address and then you decided to publish Notepad and Adobe Acrobat Reader, these applications also draw a Virtual IP from the defined pool of IP addresses even if they are not specified in the �Monitor the following processes list� in the farm properties.

If you only have a small range of IP addresses and need them all dedicated to the CTI application, you should not publish other applications on that server. Applications that require Virtual IP should be �siloed� on dedicated servers where users cannot inadvertently draw from the IP address pool.
