[QUOTE="RadDave, post: 1603816, member: 234411"] Hi [B]MacLover....[/B] - I hope that [B]Chas_m[/B] and some of our IT professionals post some definitive information on this topic because the subject remains confusing to a non-IT expert such as myself although I've been reading about and trying to understand the interaction of firewalls w/ web traffic for a long time. BUT, keep in mind that there are thousands of 'ports' that permit information from elsewhere to enter or exit your computer - kind of like thinking of a large hotel w/ numerous windows - these may be closed or opened, if the latter one can come in or get out, so 'firewalls' are meant to prevent 'incoming' traffic from entering and 'outgoing' traffic from exiting. Thus, firewalls may be managing one or the other of these traffic directions (or both, I guess, depending on the hardware/software). A main issue in running 'multiple' firewalls is whether there are conflicts in managing these ports, e.g. maybe your router's firewall wants to prevent incoming traffic from somewhere and the OS X firewall allows the traffic - one can only imagine the potential issues w/ the number of ports that exist on a computer (64K, I believe although apparently only the first 1K or more are the important ones). I'll simply stop there and hope our IT pros will 'chime in' to help clarify this topic at least partially - I've had my two Macs for 18 months - had the OS X firewall (FW) OFF the first half of that ownership (both computers behind my AirPort Extreme) - I activated the OS FWs earlier this year and have not noticed any problems and change in behaviour - I would suspect that if the FWs are acting similarly that is what one would expect?
