PIX Firewall Configuration

The PIX NAT/firewall device was originally developed by Network Translation. PIX stands for Private Internet eXchange. It was designed to utilize the new (at the time) private IP address ranges from RFC 1918. It runs on a dedicated real-time computer. The PIX was originally designed as a device for network address translation (NAT). Security came later. A PIX is not a router (well, maybe) and does not run IOS. This Study Guide covers the basic configuration for the PIX and discusses what you need to know for Cisco certification exams.
