Firewall Builder, also known as Fwbuilder, is a vendor-neutral configuration and management application for firewalls. The application was created for the Linux operating system; versions are available for other operating systems, including Windows and Macintosh. Both network administrators and hobbyists managing home-based local area networks (LANs) can simplify management tasks with the application. Fwbuilder supports the OpenBSD Packet Filter, Cisco PIX Series security devices, and iptables and ipfilter Linux utilities.
