I'm still getting the same message for external HTML Access: "Unable to connect to desktop: There is no available gateway for the display protocol."
The 3rd-party firewall rules are in place per documentation from VMware, which also matches what people have mentioned on the forums (including iefke's Blast diagram). I have used a simple telnet test to confirm the following are all open and accepting connections:
1. TCP/8443 from external/WAN to the Security Servers
2. TCP/8443 from the Security Servers to their paired Connection Servers
3. TCP/22443 from the Security Servers to the virtual desktops
(For the record, the Windows firewall service is running but the profiles are set to Off. Based on nikonau's results, it sounds like this is acceptable.)
I can login to the web interface, but when I select the pool I get the error described above. Watching the network traffic (or lack thereof, actually), I don't see any attempted 8443 traffic coming out of the Security Server during this test. I would expect to see 8443 from the SS to the CS, and then 22443 from the SS to the desktops. The only thing I see is a short back-and-forth between the SS and the respective CS on port 8009.
Any ideas?
Thanks.
