The picture below shows up the setup I would like to have:
In summary, I have 2 Android devices with internet connections, and both are sharing their connection using Android USB tethering feature, then I want to merge both connections in Ubuntu notebook into a one single fast connection and after that, share this new merged connection through eth0
(LAN) interface.
I've check some how-to to make a bonding in those connections into a bond0
interface but I am not sure if this will work.
Once I need this bond0 interface to be my eth0
sharing the internet access. Some IPTABLES maybe needed, but I does not know how to handle it.
I searched some old paid solutions for Windows, such as Speedfy/Connectify dispatcher, but I need to do this in Ubuntu and for free.
