Vuurmuur - fighting cats guard your network

Vuurmuur - behind such a "cat" name there is a quite powerful GUI add-on for iptables. The main difference from other iptables add-ins is the presence of a console interface written in Ncurses . Therefore, administration is also easily possible via SSH or console. Vuurmuur can work with shaping, supports traffic monitoring functions, maintains individual logs, works fine on both 2.4 and 2.6 kernels and even "speaks" in Russian.
