The problem basically lies in the fact that directly trying to route with non-internet routable ip addresses. How does the gateway (.254) no where to send the 192.168.x.x traffic; even if the 192.168.x.x network was routable in the internet? You aren't running any routing protocol to your providers router. Now if you could take a static address that your dsl provider gave you and use that to NAT with, then you'd be in business.
