which is best free firewall

Hmm.. Close competition between Jetico and Commodo ...
Jetico is better in features but Commodo has edge in interface .. So if you are comfortable in setting up advanced packet based rules, Jetico is the best ..

Zone Alarm. I Am Using And It's Very Light Program

Comodo (was proven better than jetico too )

I prefer zone alarm

comodo

+1 for COMODO (credit goes to kalpik, who first mentioned it)

I would go for ZoneAlarm....

I would go for Kerio

zone alaram... but also try coomando for ur interest....

I suggest Zone Alarm or Jetico. Both are good. Choose anyone.

I am using Zone Alarm right now. Good one. Comodo, being a free firewall, is also very good.

comodo for performance only (best in performance)
kerio for ease of use(better than comodo)
it also gives very good performance
so ill say kerio

these days commodo/jetico r being rated as the better ones...
...but i use za.

comodo for me...

using ZoneAlarm Pro.

has a good AntiSpyware too.

well me a little Old fashion... i dont make much of a change till its necessary... and if the Fire Wall goes... ZA have done the job over the years...

anyway few names have came up... have to try them...

i use comodo..

ZoneAlarm works fine for me

Expert/Advanced Users: Jetico and Comodo give greater control
Knowledgeable Users: Kerio has some great features while maintaining Ease of Use
Normal User: Zone Alarm Personal cannot be beaten for its simplicity, but it lacks a few advanced features

If its free what u want, than just go for Zone Alarm, itz the best u can get.

COMODO Personal Firewall...
I was using Zone Alarm till yesteryear. But the new year brought in COMODO.

Read some reviews:

*www.all-internet-security.com/top_10_firewall_software.html
*www.pcmag.com/article2/0,1759,1969207,00.asp

It's a good firewall.

NETFILTER IPTABLES- uber cool One with firestarter

I have used Zone Alarm(ZA) as well as Comodeo Personal firewalls.
I am more happy with Comodo.

zonealarm does well in blocking unnecessary ports.

Comodo ...
