Checklist: How to configure a PIX firewall

When shipped from Cisco, each PIX firewall comes with a basic configuration boot-up, but PIX does not let network traffic pass through until the firewall is configured to do so. Resource-strapped small and medium-sized businesses (SMBs) may have trouble doing the initial configuration of a PIX firewall if they don't have anyone with experience on staff. Network service providers can use this checklist to ensure that initial configuration goes smoothly in customer shops.

The initial configuration examples used in this checklist are based on PIX Firewall software version 4.0.
