Changes

In [[Ubuntu 10.x Firewall Basics]] we looked at ports and services on an Ubuntu system. We also briefly looked at iptables firewall rules on Ubuntu including the creation of a few very simple rules from the command line. In this chapter we will look at a more user friendly approach to iptables configuration using a tool called Firestarter. As we will see, Firestarter provides a high level of control over both inbound and outbound network traffic and connections without the need to understand the lower level iptables syntax.
