Linux Firewalls
 

I am looking for a good firewall for linux. When I used windows I always used zonealarm but now that I switched to linux I need to find a new one. I have heard of shorewall but havent found much feedback from users on it.

Any suggestions on a good linux firewall wil be much appreciated.

thanks

Alot of people find the firestarter front-end for iptables to be helpfull in easing the transition to linux firewalls.

I used the iptables script from the back of Oskar Andersson's tutorial . It wasn't as difficult as I first thought to change - all was there, except my banned-ip-list...

If you want an easy to use gui, I wouldn't use Shorewall. I prefer guarddog. It's easier to specify protocols etc. I've heard other users that are satisfied with firestarter aswell.

I like guarddog myself, it was very easy to set up. Its default setting is to block(or drop) everything. From that point you just check off what you need opened. .

The best that I have found is APF (Advance Policy Firewall) from http://www.rfxnetworks.com/apf.php

It is very easy to install, implement and understand.

Mandrake Linux comes with Webmin, http://www.webmin.com/ and drakfirewall, which are both pretty good front ends to shorewall. Although, they probably aren't as easy to use as the zonealarm clones other people have been recommending, it provides you with some nifty tricks like being able to set up masquerading and address translation (although for all I know the other firewalls recommended have this too).

Check out webmin if you are new to Linux. I use it to administer a number of servers without needing to ssh into the box. Lots of uses.
