This chapter covers the configuration of Ubuntu to connect to the internet via a broadband DSL modem. Before proceeding with this chapter, it is important to understand the dangers of connecting a system directly to a DSL modem. Once the connection is established the Ubuntu system will be directly visible to anyone on the internet. It is important to ensure that you have a firewall installed and running on the system to protect it from outside attack. The Firestarter firewall provides an easy to use and flexible firewall configuration environment. Before reading this chapter we recommend first reading [[Using Firestarter to Configure an Ubuntu 10.x Firewall]].
