Running Win10 ent VM on Hyper V but no internet, V switch has its own Adapter but it has an IP from our DHCP but no internet?

I have a nested Windows 2012 R2 server running Hyper V, a Virtual switch with its own Network adapter and set for external traffic.  Then I have a Win 10 Ent client running virtually and it gets a local IP ok but it cannot get on the internet nor ping anything else on the LAN?

What am i doing wrong?

Thanks
