Doesn't work with only one network interface
One of the fundamental architectural requirements is that NetScaler requires 3 network interfaces. However when you deploy this AMI it only comes with one. No problem right? just manually add the other two? Wrong. If you try this your NetScaler becomes unresponsive, you can't access the http/https or the SSH or anything else.
Citrix support does not care enough to even look into this issue. It's almost like they never tested this other than powering it on to see if it worked.
