What is the Best Firewall for Linux?

[Sputnik1]

Hi

I am running Ubuntu 10.10 in Linux and have heard that it comes with a Firewall called Iptables is that correct, and if so is there any reason to download ClearOS

Only if you want the interface and features built into clearos without configuring them into ubuntu.

Any linux distribution can be used as a firewall and security features if the appropriate modules are compiled into the kernel. iptables is merely the package to control those kernel features, other solutions exist to manage and control the network configuration and monitor it. A popular one is shorewall, but there are many different choices.

If you've already got Ubuntu installed, stick with it.

It's not really a firewall, per se, but a hardeninig tool -- bastille. You'll need to perform three commands from the terminal to install and configure it. Don't try NOT to use the terminal, IYKWIM.
After updating your repositories, do the following

sudo apt-get install perl-tk && sudo apt-get install bastille

then reboot with--

sudo init 6

Go back to terminal and --

sudo bastille -c

Choose the defaults for most, when in doubt. And change those options you know about, like Y to Disable telnet, NFS & Samba, Apache (use SSL instead, as applicable).

One can always go back to the console and run the bastille -c command again to further modify.

EDIT: i hope this works for 10.10 -- why not stick with the LTS?
