LutelWall (formerly known as Lutel Firewall) is high-level firewall
configuration tool. It uses a human-readable and easy-to-understand
configuration to set up Netfilter in a secure way. It can be used to
build a range of firewalls, from very simple, single-homed ones, to
complex ones with multiple subnets, DMZs, and traffic redirections.
It can be used on a dedicated firewall system, a multi-function
gateway/router/server, or a standalone system.
