Help Sharing Internet to Router with eth0

Hello,

I was wondering if anyone can help me figure out how to get kali 2.0 to share my internet from wlan1 to eth0. When I hook up the Ethernet cable I can connect to any of the 4 ports on the router, however as soon as I switch the cable to the incoming internet port of the router kali just says its connecting and seems to halt there.

I know I do this all the time with Ubuntu and it used to work the same in kali, just go to the network settings and change the IPV4 settings to "share with other computers". It looks like kali 2.0 is already set up to do this, I just can't get eth0 to connect.

I'm assuming its something stupid on my part but google isn't turning up anything on this topic. In the mean time I will keep trying to figure it out.

Thanks for reading :)
