This seems to be the consensus out there on the web: firewalls are great for power users, who understand what a firewall is for and know how to properly configure it to achieve what they want. For everyone else, enabling a firewall is unnecessary at best and infuriating at worst. Still, if you want to turn a firewall on and configure it, you’ve got options. Let’s go over them.
