The Installation and Configuration of a Cisco PIX Firewall with 3 Interfaces and a Stateful Failover (PDF, 1.89MB)Published: 29 Apr, 2002
Created by

This paper is intended to guide the reader through the installation and configuration of a Cisco PIX firewall. The configuration consists of inside, outside, and a DMZ network. A fourth interface will be used to provide a high-availability stateful failover situation. In this paper I will be using a Cisco PIX Model 525 firewall running software version 6.2. I do not review licensing issues in this paper. My intended audience are those who know the basics of a firewall, and have general PC knowledge. I also assume that the reader knows some basic Cisco configuration commands. They should know what the user mode and privilege modes are and well as the configuration mode. They also should know the concepts behind routing, filtering, TCP/IP, subnetting, ports, and terminology of networking in general.
