This setup might work, if you get the routing right. Set the default Route to the interface where your internet is connected to. If it is a Windows be careful to set up only one default route (this gets wrong easy and is hard to catch)
But i would not recomment this setup, try to use a (virtual) firewall or at least a router and learn about trunks/tagging to avoid buying unnecessary nics.
