As @Eigenvektor and I kind of discovered going back and forth on sharing an Internet connection though a Windows computer it allows connections leaving the computer but not all connections are allowed back in. (This could be an issue related to IP/Subnet Mask or it's a Windows Firewall issue).
Yeah, I've read a bit more about it since then. It's basically a very simple form of NAT that can't be configured. The device the connection is shared with can connect to the Internet, the computer the connection is shared with and the router, but the other direction isn't supported.
This is only possible with the Routing and Remote Access Service (RRAS), which is only available on Windows Server.
