Vuurmuur is a middle-end and front-end for netfilter and iptables that is aimed at system administrators who need a decent firewall, but do not have netfilter specific knowledge. It converts human-readable rules into an iptables ruleset (or optional a bash script), makes netfilter logs readable, and includes an ncurses GUI.
