1. The Bifrost Network Project aims to find stability, performance, filter capabilities, administration, computer security, scalability and development possibilities of a Linux based streamlined router/firewall system. The hardware is basically a standard PC with two (or more) network interfaces (using preferably the Intel Tulip chip or an e1000 Gigabit card) and a 45 or 48 MB flash disk. The operating system is a modified, minimal and optimized Linux distribution, with the kernel configured for firewalling and routing. The filter which controls the firewall security policy, is part of the kernel code and can be configured via ipfwadm, ipchains or iptables. From LWN Distribution List
