Personally, I haven't been using a <i>software</i> firewall. Instead I have a hardware firewall (a Pentium I computer running BBIagent), and my computer's stealthed right now. If anyone hacks it's ports, they only get to that computer, and not my main one it's connected to (I hope). Software firewall has been giving me trouble, like sometimes slowing down my internet connection. Or, sometimes causing instability. But, I'll eventually install one again when I feel like it.
