Fwbuilder is a unique graphical firewall tool that allows the user to create objects and then drag and drop those objects into firewalls, to build a powerful security system for a single PC or a network of PCs. Fwbuilder supports a wide range of firewalls (Cisco ASA/PIX, Linux iptables, FreeBSD's ipfilter, OpenBSD's pf, and more), so its rules can be deployed on multiple platforms.
