'''m0n0wall''' was an embedded [[firewall (networking)|firewall]] distribution of [[FreeBSD]], one of the [[Berkeley Software Distribution|BSD]] [[operating system]] descendants. It provided a small image which could be put on [[flash memory|Compact Flash]] cards as well as on [[CD-ROM]]s and [[hard disk]]s.  It ran on a number of embedded platforms and generic PCs. The PC version could be run with just a [[Live CD]] and a [[floppy disk]] to store configuration data, or on a single Compact Flash card (with an [[AT Attachment|IDE]] adapter). This eliminated the need for a hard drive, which reduces noise and heat levels and decreases the risk of system failure through elimination of moving parts found in older hard drives.

On February 15, 2015 Manuel Kasper announced the "m0n0wall project has officially ended. No development will be done anymore, and there will be no further releases," encouraging "all current m0n0wall users to check out [[OPNsense]] and contribute if they can."<ref name="EoL">{{cite web|last1=Kasper|first1=Manuel|title=m0n0wall - End of the m0n0wall project|url=https://m0n0.ch/wall/end_announcement.php|date=February 15, 2015|language=en}}</ref><ref>{{cite news|last1=Chirgwin|first1=Richard|title=M0n0wall comes tumbling down as dev throws in the trowel|url=https://www.theregister.co.uk/2015/02/16/m0n0wall_coming_down/|work=The Register|date=February 16, 2015|language=en}}</ref>

== Features ==
m0n0wall provided a [[Internet|web]]-based configuration and used [[PHP]] exclusively for the [[Graphical user interface|GUI]] and [[booting|bootup]] configuration. Additionally, it adopted a single [[XML]] file for configuration parameters.

Some functions of m0n0wall were:
* Stateful packet filter [[firewall (networking)|firewall]]
* [[IPsec]] and [[Point-to-point tunneling protocol|PPTP]] [[Virtual private network|VPN]]s
* Inbound and Outbound [[Network Address Translation]]
* [[Captive portal]]
* [[Network scheduler#BSD|Traffic shaper]]
* Inbound and Outbound port filtering
* Support for [[802.1q]] compatible VLANs
* Multiple IP addresses on LAN and WAN ports
* IPS

m0n0wall was installed on embedded hardware designed and manufactured by some companies.

* [http://smallwall.org/ SmallWall]: Another 2015 fork of m0n0wall after its end-of-life, no activity since 2016.
* [http://code.google.com/p/m0n0wall-mod/ m0n0wall mod]: Original m0n0wall with additional features (DHCP+PPTP, DHCP+PPPoE, static+PPPoE, L2TP, WAN eth interface), no activity since 2013.

;Other usages (not a firewall):
* [[AskoziaPBX]]: An embedded telephone system.
* [[XigmaNAS]]: [[Network-attached storage]] software using FreeBSD, uses portions of m0n0wall web [[GUI]].  Formerly NAS4Free.
* [[TrueNAS]]: [[Network-attached storage]] software with versions in FreeBSD and Linux. Developed and maintained by [[iXsystems]]
