Server 2016 RRAS Allowing Internet Access Through VPN

I need to add the ability to have connected clients access the internet through our corporate network through the VPN. Both of my networks have internet access however the internal network has no ports open directly to it. I've tired a couple things with no luck not sure exactly what I need to do. I know the clients use the RRAS server as the default gateway so I attempted setting up a couple NAT configurations with no luck.
