Operating system
floppyfw was a Linux distribution running BusyBox to provide a firewall/gateway/router on a single bootable floppy disk, but was later available in CD format.[1]
Reviews concluded that it was a very simple and reliable gateway/firewall that could be established on small to medium-sized networks at low cost and with ease.[1] One independent study concluded that it was " best possible security provided by a floppy-based firewall" for the repurposing of old, redundant hardware into Linux-based firewalls or routers.[2]
