Configuring Firestarter
Ubuntu is unique among distros in that as default it does not listen on any network ports. This means that it is pretty much secure. However, you may have a requirement to open up ports for access by other local computers.
To configure the firewall, you need to download and install the firestarter package using either synaptic or apt-get. When installed, you can use it to open specific ports or even allow access to specific computers. It's a handy application, and you can find more details at http://www.fs-security.com
