The Problem:

As big as Ubuntu is, I am really surprised there is no firewall included by default. Yes, I know that the functionality is built into the kernel, but do you think half of these newbs running Ubuntu know about iptables?

The Solution:

Guarddog is a GUI Linux iptables/ipchains configuration utility. This is going to save you from having to spend hours of reading about Linux firewall setup and setting up rc scripts, etc.

sudo apt-get install guarddog

Now you have a menu item under Applications -> Internet -> Guarddog. It is pretty much useless unless you are running as a superuser, so run

sudo guarddog

You should get a prompt about not having a rc.firewall, click ok.

Guarddog’s philosophy is to block if not allowed, just like any firewall. Keep this in mind if you go to try to play AssaultCube and it won’t connect.
