Establishing Connectivity

This chapter describes the basic preparation and configuration required to use the network firewall

features of the Cisco

PIX Firewall. After completing this chapter, you will be able to establish basic

connectivity from your internal network to the public Internet or resources on your perimeter network.

The basic configuration described in this chapter lets protected network users start connections, but

prevents users on unprotected networks from accessing (or attacking) protected hosts.
