Henry, I assume you're kinda new to linux, so I'll keep this simple. First, configure your firewall -- that is, you just have to start it the first time, that'll be ok. After you've done that, open a terminal window, and paste the following in it (without the quotes): "gksudo gedit /etc/firestarter/firestarter.sh". That will open you an editor window. Now, seek in there the following lines (probably line 33 in the file):
------
	echo "External network device $IF is not ready. Aborting.."
	exit 2
------
edit the second line so it becomes:
------
	echo "External network device $IF is not ready. Aborting.."
#	exit 2
------
Now seek these two lines (line 39 I think):
------
		echo "Internal network device $INIF is not ready. Aborting.."
		exit 3
------
edit the second one so that it becomes:
------
		echo "Internal network device $INIF is not ready. Aborting.."
#		exit 3
------

This will probably fix your problem and you'll have a running firewall.
After doing this, you'll probably have to restart your computer. If you
want to check whether your firewall is running, just do "sudo iptables
-L -n" in a terminal.

If it doesn't give you this (see below), and it returns many many lines of text, then it means the firewall is active.
------
      Chain INPUT (policy ACCEPT)
      target prot opt source destination

      Chain FORWARD (policy ACCEPT)
      target prot opt source destination
      Chain INPUT (policy ACCEPT)
      target prot opt source destination

      Chain FORWARD (policy ACCEPT)
      target prot opt source destination

      Chain OUTPUT (policy ACCEPT)
      target prot opt source destination
      Chain OUTPUT (policy ACCEPT)
      target prot opt source destination
------
