I never used any of these Firewalls before, but I read on a lot of forums and websites I found online which recommends these Firewall Linux distros. for securing your internet and network.
I might make a tutorial on Smoothwall, IPcop, and Devil-Linux when I have the time.
These Linux based Firewall operating system are best for corporate, or higher end users which need more flexiblity and security compared to the default firewall which comes bundled with most routers and operating systems.
I installed Ubuntu 9.10 Alpha on a Virtual Machine with Sun's VirtualBox. Installing 9.10 is very similar to installing previous versions of Ubuntu. It also can be set to dual boot Windows and other Operating System with the GRUB boot loader that is installed when you install Ubuntu. I find the start up screens, and the wallpaper to be nicer. Ubuntu also seem to added a few wallpapers. It starts up and shutdown pretty quick to. The biggest improvement is the software install and uninstall tool. It is very easy to use. It is not too different from Ubuntu 9.04. The wallpaper for 9.10 also seems nicer then prevous versions of Ubuntu. I notice the Icons and Wallpaper to look better. I can't wait for the official Ubuntu 9.10 to be released in less then 10 days.
Some Screen captures of Ubuntu
Most Improve feature is the Software Center Applications because it makes installing and removing unwanted software.
