I have Leopard and have all the software updates. I'm on 10.5.1 Seems that the firewall settings don't do anything. I've put it now on "Set access for specific services" yet it does nothing. Doesn't block anything, doesn't ask for permission before using a program or anything. I've even put Firefox as an application and set it to "block incoming connections" but it does nothing....Firefox plows right through and loads pages up like before. I've even put it on "Allow only essential services" and it still doesn't block anything. Firefox again loads everything. Can even play Warcraft with that checked. I doubt Warcraft is an "essential service". Do I have to set the settings then log out and back on? Do I need to reboot to get the settings to hold? What am I doing wrong?
