Unbelievably Norton Firewall allowed penetration, when i used the famous Leaktest.exe
So i have installed Comodo Firewall 4.0 (a part of Comodo Internet Security), i was able to block the leak successfully. GUI looks cool. I will test Comodo for a while. Seems more reliable than Online Armor.
I tried installing PCtools firewall, but it said it would not be compatible with NIS.
