How Do I Access My Nutanix Cluster From Outside My Network?
The Enterprise Cloud android app needs to talk to Prism. By default, the Prism interface is available on port 9440. So, if you want to access your Nutanix cluster from outside your network, you need to make port 9440 available from your CVM cluster IP to the outside world.
If you are a home user, you may be OK with just forwarding port 9440 through your network to your CVM.
Another option is to use a VPN of some kind. I’ve heard of some users leveraging the OpenVPN android app, as well as utilizing SSH tunneling for Prism access without forwarding any ports.
