I am working on a project to use a FRDM-KW41Z evaluation board as border router. I am able to compile and run the Thread stack in the evaluation module. I am able to connect to a thread network as well. But to use it as a border router I am interfacing a third party ethernet controller with the evaluation board. The ethernet controller is able to communicate with the evaluation board. But I am not able to establish internet communication. The internet connection I am using from a IP4 router. I am sure thread stack has support for IP4 routers.
Please guide me how I should proceed
