Posix_Sockets example

Hi guys, does anyone know how to get a Board communicating with a native node using the posix_sockets example?

I managed to get 2 nodes (on native) communicating successfully. I also managed to get 2 “SamR21-Xpro” boards communicating successfully via a border router.

How do I get the Board to use the same as the native node on RIOT?

Regards Brenton
