The Administration Interface is the main interface used to configure Untangle. A welcome message is displayed upon the first visit to the administration interface. It will make a suggestion about the suggested applications that may be useful for your network. You can follow the welcome screen suggestion or just close the welcome screen and install the applications manually.
Untangle's administration can be divided into two main parts, the Navigation Pane on the left and virtual Racks on the right.
The Navigation Pane contains two tabs - Apps and Config, detailed below. The Apps tab on the left-hand side is used to learn more about applications and install applications into the "virtual rack." The Config tab contains several sections to configure the Untangle server's settings.
Applications are installed into one or more virtual Racks on the right hand side, and filter the traffic passing through the Untangle server. Each application has a faceplate with a Settings button to configure it, current status information and a power button to toggle it on or off.
Across the top there is a dropdown menu to switch to different Racks or use the Session Viewer and Host Viewer, as well as readouts for network speed statistics, a count of open sessions, CPU, memory, and disk information.
If you see an alert icon near the top of the web GUI, hover over it for more information - these are Administrative Alerts designed to help you keep your Untangle healthy.
