Description:

Vuurmuur is a powerful middle-end/front-end for netfilter/iptables aimed
at system-administrators who need a decent firewall, but don't have netfilter
specific knowledge.

The program is basicly split into three pieces. One piece (the middle-end)
converts humanly-readable rules, hosts, groups, networks, zones, interfaces
and services into a iptables ruleset (or optional into a bash-script). The
second part is a little daemon that converts the netfiler logs to easy
readable logs, that reflect all the predefined objects described above. The
third part is a Ncurses-based Gui (the front-end) in which one can manage
the firewall. Most important here is the real-time feedback. Logs can be
viewed in real-time, using colours for easy interpretation. Also, the current
connections can be viewed in real-time. Filtering possibilities make it easy
to monitor specific hosts or services.
