Open Source firewalls?

Are there any free open source Firewall out there that are really good?
A company like Firefox that nake free programs for free.

Like is there an open source firewall using for example the zonelabs engine, kerio, Mcafee etc...


And are they better than Comodo my current firewall.

 

see this thread. the choices dont seem good though.

an heres an open source packet filter: http://wipfw.sourceforge.net/

 

Anyone think Comodo is the best firewall at the moment for protection?

Its the best firewall at the moment for blocking leaktest right?

And does Comodo do packet filter? wat is it anyways?

 

afaik comodo is still the best for leaktests.

see here for packet filter (wikipedia). Comodo does have packet filtering, its called "Network Monitor".

 

Hello,
Open source firewalls for Linux are plenty and work great. The problem is with open-source firewalls for Windows.

Regarding leak tests....

I run ZA 5.5 on my personal box. Has not failed a leak test yet. "How?" you may ask. Since the leak tests mostly use IE exploits to accomplish their work, and I do not use IE as my default Browser, I have it set to ask for Internet access permission. When I trigger a leak test ZA lets me know IE wants out, simply deny it. (guess I just do not trust IE at all)

 

So leak test what are they programs that try to by pass the firewall security? and what do they always have to pass through Internet Explorer? not Firefox?

 

They attempt to establish an out bound connection. Simulating like you were infected by a trojan.

Due to vulnerabilities in IE, not Firefox or some other browsers.
