ClosedBSD – a FreeBSD derived firewall distribution bootable from a cdrom, compact flash, or floppy diskette. It features a complete curses based user interface for managing your network interfaces and firewall rulesets. ClosedBSD includes a powerful ncurses-based configuration manager, allowing the user to easily customize the firewall and NAT settings using a simple interface.
One of the advantages of ClosedBSD is, it can be run directly from a floppy or CD-ROM without need of a hard drive. It can also run on relatively old hardware; the floppy disk version requires an IBM-compatible PC with 8MB of RAM, while the CD-ROM version requires 32MB of RAM.
The latest versions are the 1.0B for floppy disk and 1.0-RC1 for CD.
Its binaries (executables) are freeware, that is, released for use at no cost. Distributed under the terms of the BSD License, which is a free software license. The source code is not, so it’s not free software, its source code is not available to anyone who wants to improve it.
