im with the granda poster
you shouldnt lower the task of firewall security.
pretending that the audience target of this articles is windows users who happen want to and give a try to freebsd is not right. I understand Dru position here, trying to get to a more wider audience and not be too much techinicall about some subjects.
But freebsd boxes should be protected by some kind of firewall (period). If you happen not to know what a firewall is, dont use freebsd. Its impossible and not eligeble to be comprimissed using a freebsd box by the simple fact that you are not behind a fw or using a lowcrap setuped firewall that even a syn flood cant deter.
Isnt the awareness of security but the feeling you arent doing whatever you can to avoid it that should oblige everyone to take action.
Learn iptables, learn ipfw, or ipfilter whatever but dont use a point and click fwall since the diference between that and nothing is NULL.
