rosjava on Android device with local network address

I'm trying to use rosjava on Android devices with 3G network connection. But some devices obtain local IP addresses.

I think we have to use VPN or SSH tunneling for communicating other nodes.

But I think these ways are not good to force users to do. Is there any other solution?

Most mobile service providers (at least here in germany) are using network adress translation for the mobile clients. Since ROS needs bidirectional direct connectivity between alle nodes, i would guess that there is indeed no other option than using some sort of tunneling.

Maybe you can find a solution that doesn't need ROS-Nodes directly on the mobile clients, but have a server offering some of the functionality as a webservice, which is then called by the mobile clients.

In fact i would prefer the (web-)service approach, since ROS itself provides no sort of authentication and/or authorization, so any client would be able to publish and subscribe to any topic they want...

Thanks for your answer. Making a web service is a better approach, but developing web application with high transparency to ROS network is difficult for me. No authentication may become a problem in the future indeed. Tunneling seems to be a only way to use android.rosjava applications.
