Want to try the authenticating firewall without to bother installing anything, get the NuFW liveCD now.

Bittorrent: http://live.nufw.org/dl/nufwlive-1.0.iso.torrent
LiveCD URL: http://live.nufw.org/



This live CD allows you to run a complete firewall that you can administrate graphically with NuFace. You set up users using the KDE system user creation tool and then you authenticate your workstations either with the Linux client nutcpc or nuapplet2 (apt-get install) and/or your windows machines with Nuwinc.

And you can of course backup all of this to restore your firewall after a liveCD restart.

Being a liveCD, you can make a gateway firewall that is read-only and enjoy real security.
