Cisco PIX Firewalls: Configure, Manage, & Troubleshoot

The PIX has many different configuration models to ensure that the product will be suited to different environments. Obviously, the requirements of a SOHO user will be different from those of a service provider. Cisco has provided various classes with different price points to ensure optimum product placement.
Five models are currently supported: the 501, the 506E, the 515E, the 525, and the 535. However, there are three models that you may see deployed in enterprise environments: the 515, the 525, and the 535. As it turns out, these are the three models that the new 7.0 code will run on. The 7.0 code at the time of this writing does not run on the SOHO models, which are the 501 and 506E. Table 2.1 shows the vital characteristics of each of the models.
