Hi all,

I'm working on an expiremental project using Android and OpenStack. For now we have 3 servers running Ubuntu Server 14.04 and OpenStack Icehouse, one is the controller node, one the network node and the last one the compute node.

The aim of the project is to create a kind of cloud gaming platform for Android users. Until now we managed to have the server / client software running. Suppose an Android tablet owner is at home behind his router and my server public ip is When the user click on the app button on his Android tablet, a socket connection will be created and the tablet will connect to the server at the server ip and port 12345. The server is running the game and sending back the images through the socket. That works.

Now we want to scale the service. So instead of having one physical server, we would like to have instances on an OpenStack cloud. We managed to install the cloud following the OpenStack documentation for Ubuntu and we created 3 instances VM1, VM2, VM3 with private ip,, so that up to 3 clients can play at the same time with their tablets.

The problem is that we don't have 3 public IPs but just one. How could we solve our problem? What we would like to do is the following: - We have a webservice on IP - We have an OpenStack Neutron router on IP When the tablet launches the app, it connects to the webservice. The webservice tells the controller node to start a virtual instance (let's say VM2). The webservice tells the tablet that it should connect to VM2(with address behind the router at public address

Thanks for your help! JB

The title of your question put me off. I think that Android has nothing to do with the problem you want to solve. Isn't this more of a classic NAT issue? maybe changing the title will make networking people more attracted to chime in.

Hi smaffulli, I changed the title to be more broad on the question

I guess LBaaS will help here.

Using LBaaS you can create custom configuration, that your clients/tables will use one floating IP (200.20.20.x) for connection to the server, while LBA will distribute/route the access to internal network (192.168.1.x)

Good Luck!
