CirrusVMware View Black Externally
Just curious if anyone has run into a black screen using View on external VIP? On our internal VIP it works great. Running 11.4.1, latest iApp, 4172 is open inbound to the external VIP. This is launching from the webtop link that is created with the iApp. It opens the View client, logs me in, starts the session, then a black screen.

As you probably know, a black screen indicates a PCoIP problem. Couple of questions for you: Are you using and iApp to configure your external VIP, and if so what version? Can you verify the external connection has a route to your VDI? Are you using PCoIP Proxy or are you just forwarding the PCoIP traffic onto your VDI?
travis99_94012Yes on iApp - 1.0.0rc5. We have a two leg F5, one in DMZ and one on internal network, the current route is set to use the internal gateway. I set it up with PCoIP proxy.
What version of View are you using? PCoIP proxy with BIG-IP requires server and clients to be at a minimum version of 5.2.

Yep, we're at 5.2
Can you verify your server ssl profile has the following in the server name field:pcoip-default-sni
- travis99_94012
Yes it does, just like the internal VIP.
Try running a TCPdump on the BIG-IP for UDP:4172 to verify the traffic is making to the BIG-IP and being sent to a virtual desktop address.

I may have discovered a little irk externally. It starts the connection, then it attempts to connect again throwing off the initial connection and fails. So I'm attempting to track down where it's doing this in APM. TCP dump on internal connection was good, 4172 traffic flowing on designated VIP.

hi Travis, did you find a solution to your issue with the black screen? I am trying to set up exactly the same environment, but I am stuck also with the black screen and I already lost all clues..- travis99_94012Yeah, I missed the "optional" instructions if you're external IP is behind a NAT. Page 58 of the guide. I'm also waiting for my own test connection server so I can do everything the guide asks to do on the CS. (Optional: If using a translation device between the View Clients and the BIG-IP system) Click the + symbol between AD Auth and Advanced Resource Assign.
- Martin_VlaskoI have tried that as well, but no luck. Now I moved my test client on an external network that can reach external F5 VIP directly, without NAT, so that the "optional" feature is not required, but it still does not work. After successful authentication I am able to choose from the virtual desktops.. when I choose one, the VM window opens, but with the black screen. In exactly the same time when the VM window opens, I can see packets on each side of the F5. The number of packets is the same on each side, so I assume they are related. on the external side, from the client to F5 VIP it is TCP/443 traffic, on the internal side, between F5 internal self IP (VIP) and the chosen virtual desktop it is TCP/4172 traffic. But there is absolutely no UDP traffic anywhere..

You need to modify external default gateway to match your LAN gateway.
