White Paper: Indestructible Firewall in a Box V1.0

Tags:
firewalls

Overview In this paper, the procedure for creating an embedded firewall whose root filesystem is loaded from a flash disk and then executed from a RAMdisk will be illustrated. A machine such as this has uses in many environments, from corporate internet access to sharing of a cable modem or xDSL connection among many computers. It has the advantages of being very light and fast, being impervious to filesystem corruption due to power loss, and being largely impervious to malicious crackers. The type of firewall illustrated herein is a simple packet-filtering, masquerading setup. Facilities for this already exist in the Linux kernel, keeping the system's memory footprint small.
