m0n0wall计划的目标是创建一份完整的、内置的防火墙软件包，当它配合PC使用时，能够提供商用防火墙机器的所有重要功能（连同易用性在内），而其价钱却只是后者的一小部分（因为m0n0wall是自由软件）。m0n0wall基于FreeBSD的一个精简版本，并带有一个web服务器（thttpd）、PHP以及其他一些实用工具。整套系统配置存储于单个的XML文本文件以对系统透明。m0n0wall很可能是首个拥有用PHP实现的启动配置的UNIX系统，而通常这是依靠shell脚本的，此外，它把整个系统配置都用XML格式存储。

         Manuel Kasper has released a new public beta build of m0n0wall 1.3, a FreeBSD-based firewall. What's new? "Opened firewall rules for link-local IPv6 addresses on optional and LAN interfaces; initial basic support for secondary IP addresses; added DHCPv6 support; added additional RA options for LAN and optional interfaces, required for DHCPv6; added all-servers option to dnsmasq and removed overlap check as having multiple nameservers per domain is a valid configuration; changed interface status page to list all IP addresses on an interface; allow RA support on WAN interface, and add feature to automatically suggest an IPv6 address for the LAN interface; added IPv6 support to mini_httpd (for the webGUI); allow IPv6 addresses for DNS servers on system: general setup page, and for hosts on the DNS forwarder setup page...."
