Untangle

Untangle is a platform for deploying network based applications. The platform unites these applications around a common GUI, database and reporting. Applications on the Untangle platform inspect network traffic simultaneously, which greatly reduces the resource requirements of each individual application. Untangle can act as a complete unified threat management (UTM) box, going beyond just a basic firewall or router. It's aimed at small-to-medium businesses and enthusiast home users. It runs in line as a network gateway, so it allows control of all devices connecting to the network. Untangle offers a free, open source Lite Package as well as a full-featured, commercial Premium Package. Untangle has about 40,000 installations worldwide protecting over 2 million people in businesses, schools and other organizations.
