Windows 7 Ultimate Setup At Home Allowing A VPN Connections

I have a windows 7 ultimate setup at home allowing a VPN connections via ptppp using the incoming setup.I set up the Client which is my iPad 2 and the connection goes through fine authenticating and then connected internally within the network and externally outside the network. Everything seems work prefectly.The client(iPad 2) loses internet browsing capability if I turn On the option to send all traffic however if the send all traffic is off then everything works fine. It's only my assumption that the reason why the internet works when the send all traffic is Off via my iPad 2 to the windows 7 machine is because it created a split tunnel which allows me to use the Internet without problems.My goal is to be able to turn On Send All traffic and it works. Having all data passthrough the windows machine
