Oops... Fixed above I think nLite has this option, right? I'm just using Windows Default Defragmenter and c leaner This is my NAT page in router control panel, and the guy from ISP set it to be disabled, I'm using a static or real IP, I do not know if disabling NAT is kinda related to static or real IP or not, but I'm very interested to follow your advise, so more info is much appreciated. and what simple one you recommend for a newbie one like me, because I've tried outpost fire wall and found millions of messages and alerts to deal with which was like HELL so I removed it and reinstall a clean XP, so what do you think man!? Sure this is not me man, I think it will be after 5 years from now
