    Johannes- Please help- we constantly get calls for errors “cannot start app” and “cannot start desktop”. However the user can access their virtual via RDP. If the virtual is rebooted they can then use Citrix to access but why do we have to keep doing this? Please help- what can we do to troubleshoot to find out what is causing this.

      Sorry, Kelly, this is very hard to answer and I won’t be able to help you very much. I may only push into a certain direction. I guess, it’s a problem somewhere between Citrix Virtual Apps and Desktops and Windows, but neither nor is my specialisation, I do Citrix ADC / NetScaler. Given, I am right, I would search for events on the virtual work-load (“their virtual“) and on the delivery controller. There have to be events related to this issue.

      You are asking a ADC geek, so I guess, you tried from outside. Does HDX/ICA connection work from inside? And which protocol are you using from outside: TCP or UDP?

    Hi Johannes
    So, we have deployed 2 SDX 15030-50G, one in Primary DC and the other in Secondary DC in HA. We migrated the Cisco ACE Loadbalancers to the VPXs and all tested and working. Now, in the same Cisco Chassis where the ACE Appliances are, there are Cisco Firewall Service Modules. Is it possible to migrate these Firewall Modules to the SDX? The idea is to completely retire the Cisco Chasiss and have the SDX doing the Loadbalancing and Firewall.

        By the way, even if it’s not actually supported, you could run anything that can run on Citrix Hypervisor (XEN-Server). But I would not do anything unsupported on a secure edge device. So either go with Palo Alto, or leave it as it is.

        There is another possibility: If you consider deploying Citrix SD-WAN you could use SD-WAN as a firewall. It’s a medium-class stateful inspection firewall and a damn good SD-WAN solution.
