pludi, thanks a lot for your answer. What you've said about that site, is in line with a few pieces and beats I had read, here and there. Anyway, I thought the above mentioned test was accurate, although It seemed to me that the conclusion, comparing the graphic result to the written report, was contradictory.

As you said, I understand that "hardening a system doesn't stop at configuring your firewall". The code I used for my firewall is a very basic one, taken somewhere from an Ubuntu wiki for beginners.
Linux hardening is an all vast subject that I've been trying to get through, but I'm aware that I'm yet far to have it all.

Just before closing this thread, or marking it "solved", would you recommend, just for surfing, that I eliminate the code that is closing port 80, and do nothing else, regarding this firewall?
