ok guys solved :)) I had to add a static route on the dot 2 laptop to point the ping replies of the unknown dot 1 subnet to the router! because the dot 2 laptop had the unchanged default gateway (since it's connected to the corporate's internal net) and it was replying through the default gateway! Thanks a million to all those who replied!
