I'm not sure what you got wrong, but if I may...

You should *not* expose your compute machines to the internet (and
probably not your controller either, except the API). You should set
them up with a private network address (192.168.x.x or 10.x.x.x for
example). Only your VMs should have access to internet. I would strongly
recommend revisiting your network setup.

I hope this helps,
