Why does dd-wrt shows all open ports to the outside internet? I have tried the ShieldsUP test, which recommends that all ports should be steath. When I run the test with my ISP router, all ports appear steath except the one I really want to be opened, which is port 80. Then I set my ISP router to DMZ on my dd-wrt router. Running the test again shows a LOT of opened ports visible to the internet.
Is this a problem? anyone knows how to fix?
