OpenWrt is a GNU/Linux based firmware for embedded devices such as residential gateways. Support was originally limited to the Linksys WRT54G series, but has since been expanded to include other chipsets and manufacturers, including x86. The most popular routers seem to be the Linksys WRT54G series and the Asus WL500G. OpenWrt primarily uses a command-line interface, but also features a web-based GUI interface, which is provided in most manufacturers' firmware. Technical support is provided through the forums and IRC channel.
