Can you check the event viewer for messages from the client? I'd check the logs on both the server (/var/log/apm, set accesscontrol to debug) and the client PC (event viewer). I don't know if this NAT situation was explicitly tested, so you may also want to try to use plain port 443 against a test APM VE instance.

 

Another thing to keep in mind is that Microsoft is not going to ship this Inbox client with Windows 10, so the only release with it will be Windows 8.1.
