I have been combing these forums looking for a solution to this problem. I can connect to my Windows 7 Professional VM's with no problem over secure SSL, but after connection under the USB tab at the top it says "Desktop Initializing".
Now I've seen and read many posts here, and I am certain it has something to do with my physical router/firewall. I put a Client computer on the same lan (inside the firewall) and it loads up and works just fine, complete with USB Redirection so I know the actual setup is fine. However, when I do the same thing from a computer outside my firewall, it gets stuck.
After reading other posts here, I forwarded port 32111 to my View server, and that has not resolved the problem. I even went as far as putting the View server on DMZ, and still same results.
So to summarize - it works fine from a computer on the same LAN, but when coming in from outside the LAN, it does not.
Ports going to the view server:
80, 443, 4172, 32111.
Could really use some suggestions here.
