Security Server within a Meraki MX DMZ - Desktops launch with black screens then close.
We attempted to put a MX100 into our environment last Friday, it replaced an ASA. We checked with Meraki support several times to see if the rules appeared correct for a Security Server pin hole.
We cut everything over, but never got it working. You could authenticate externally, see the desktop choices, launch a desktop -- but then the screen would launch black and never load a desktop and eventually just close with a connection error. If we switched the connection method over to RDP in the View client application it would work, but then it wasn't going through the security server.
Meraki support had no idea how to fix it, I can't find any documentation on how to do this with Meraki anywhere either. Our other thought is to maybe try an UAG but I'd rather get our current config working before overhauling it and trying to get the MX in.
So if anyone out there has Meraki and security server, please enlighten me on how you did it.
