A unique ICSA certified firewall that boots and runs entirely from a floppy diskette, (no hard disk is required). GNAT Box is a stand-alone system which includes its own OS, and runs on a dedicated system. The hardware requirements are minimal: 386 or better, 8MB-16MB RAM, floppy disk drive, 1-3 network cards, (a keyboard and display are required to perform the initial install, however they can be removed later if desired). The system can be managed from the console or web browser interfaces. The GNAT Box Light installer provides utility programs to copy the supplied GNAT Boxruntime diskette image to floppy diskette.
