Oh... Also the various docs seem to be slightly contradictory... I know it's a new thing, and has obviously changed a bit... But even on the various videos I found, it seems to contradict itself as to what VS's are required...
For Blaast (HTML5) you need a :443 VS only. It'll act as an HTML gateway to your desktop. That's kinda slow. But seems to allow me hi-res.
For Horizon View Client (PCoIP) you'll need a VS for udp/4172 on the same IP as your main :443 VS. I found some references talking about tcp/4172 (Not used) and one implying none (Wonder if that was an early one, or simply assuming you were going to use Blaast).
And if you're doing NAT externally to your bigip, you'll need to remember to add the special sauce. A variable setting in the visual policy that sets a special variable to tell the APM to re-write the proxy address as your external IP. I'm hoping that'll work as a FQDN as well to enable GTM to be used in front. Otherwise it's back to the drawing board again (Which will probably involve firewall changes so I don't have to NAT the BigIP VS address for this VS).
