I noticed a synificant change in speed with my firewall turned on, granted I have three firewalls (windows, my motherboards built in nvidia fire wall, linksys firewall) and, often only use the linksys wrt54g built in router the majority of the time.
My question is ; do i realy need to use all three? Are there any firewalls out there that just watch for attacks and then alerting you , so i could just have them turned off untill needed and Which firewalls do you recommend?
thanks
