Hello, Isn't there a problem using the same (as it seems) subnetmask for the two networks (IP addresses starting with xx.xx.xx on both interfaces) ? I would choose a different IP addressing scheme (for example 192.168.y.z on the PPP link). Hope that helps TfH > > Hiding IP addresses makes it hard to figure out what is going > on exactly.
