M0n0wall

Firewall distribution

m0n0wall was an embedded firewall distribution of FreeBSD, one of the BSD operating system descendants. It provides a small image which can be put on Compact Flash cards as well as on CD-ROMs and hard disks. It runs on a number of embedded platforms and generic PCs. The PC version can be run with just a Live CD and a floppy disk to store configuration data, or on a single Compact Flash card. This eliminates the need for a hard drive, which reduces noise and heat levels and decreases the risk of system failure through elimination of moving parts found in older hard drives.
