Hi I'm trying to implement a Load evaluator using IP range in XenApp 6.5. Effectively I'm trying to block a certain application from being accessible when users work from home. Application can only be accessed when in the office. I created a Load Evaluator using the following: CPU Utilization (left at default setting) IP Range (Set to Allow and added the internal network range) I associated the Application to the new Evaluator. Our Citrix Web Interface is hosted in another country and is not in the IP Allow range Issue 1 Application wouldn't launch even when used internally. I had to add the Citrix Web Interface IP to the allow range to fix this issue.. Issue 2 Application works internally but it also works externally so the rule isn't working.. I've had this working fine in our older XenApp 4.5 environment. Only difference is that the Citrix Web Interface was on the same network in old environment. Am I missing something? Is it possible that the client IP is not being sent correctly or is being masked at the Proxy or Citrix Web Interface? Thanks Ang
