How Best to Use This Chapter

Limiting access to systems and services on your network is one of the primary responsibilities of the PIX Firewalls that you deploy on a network. This chapter provides the information on how to restrict network traffic using access lists, hide internal addresses using Network Address Translation (both static and dynamic), as well as configuring fixup protocols that monitor common protocols to dynamically open up access through the PIX Firewall. Understanding these concepts is vital to successfully securing your network using a PIX Firewall. Test yourself with the "Do I Know This Already?" quiz and see how familiar you are configuring access restrictios on PIX Firewalls.
