How many of you guys consider it important ehough to have a firewall active.
If so, what firewall do you use, and how good do you consider it to be, or do you edit the iptables directly.

I use both router and Firestarter but I really canīt tell you why. I guess Iīm still nervous from my Win-98 days.;)

I definitely do. I keep a hardware-based NAT firewall router in my home that filters on MAC address. Then, on each workstation, I only use Ubuntu Linux (of course!) and then I always use an input-based iptables firewall script. If you're ever curious about how to write one fast, here's my EASY IPTABLES TUTORIAL (http://supermikenews.blogspot.com/2006/03/roll-your-own-linux-firewall-script.html).

I do this because it doesn't really slow my systems down too much, and because there's no harm in using an extra ounce of security especially if it's not disruptive to getting work done.

I use only the one in my router. I plan to set up as firewall an old box with debian and iptables but I don't have enough time to set it up.

I have a script that sets up IPtables for me. I also have Snort running on there so I can see any "suspicious" traffic. It has caught atleast one virus that got onto my sister's desktop, so its been valuable enough to keep around :)
