    FireHOL

    FireHOL

    A firewall for humans.

    FireHOL is a language (and a program to run it) that builds secure, stateful firewalls from easy-to-understand, human-readable configurations. The configurations stay readable even for very complex setups. FireQOS is a program that sets up traffic shaping from an easy-to-understand and flexible configuration file. Both programs abstract away the differences between IPv4 and IPv6. so you can concentrate on the rules you want. You can apply rules for IPv4 or IPv6, or both, as you need.
