I'm thinking about demilitarizing this computer from hardware firewall protection because the options in the router are just too limited. Before I do that, of course, I need to set up a software firewall on this computer. I just tried out two popular ones, Sygate Personal Firewall and ZoneAlarm, and neither of them really did it for me. For one thing, neither has the option to specifically authorize specific ports for specific applications. Basically ZoneAlarm just blocked every port but 80 and asked for your permission to let 80 through on any application that requested. Anybody have any suggestions for some good freeware? Or am I going to have to whip out the plastic for what I want?
