NG Firewall User Guide
The Untangle NG Firewall User Guide
If you have not already installed Untangle NG Firewall, read the Installation Guide.
The Administration Interface
The Administration Interface is the main interface used to configure Untangle.
A registration and 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 choose to install the recommended apps or to install the apps manually.
There are four main tabs in the administration interface in the main menu:
In the sub-menu there are four views:
The Dashboard provides an overview of the state of your NG Firewall. It is extremely useful for quickly viewing or monitoring what is happening on the network and the current status of the Untangle server.
By default the dashboard will show several widgets with varying pieces of information. However, the dashboard is completely customizable. Widgets can be removed and added so the administrator sees exactly the information that is important to them on the dashboard.
There are many different type of widgets available:
|Information||Shows some information about Untangle, like name, model, version, etc.|
|Resources||Shows an overview current memory swap and disk usage.|
|CPU Load||Shows a graph of recent CPU load.|
|Network Information||Shows an overview of the network information like session count and device/host count.|
|Network Layout||Shows an overview of the network layout based on the interface configuration.|
|Map Distribution||Shows the current sessions mapped geolocation on a world map, sized by throughput.|
|Report||Shows any Report Entry from Reports|
To change what is displayed on the dashboard click on Manage Widgets at the top. From here you can show or hide the built-in widgets, or add new widgets from Reports by clicking on the Add button.
When adding a Report widget, you must also specify a timeframe (the number of hours worth of data to display) and a refresh interval (how often the widget refreshes on the dashboard).
When viewing a Report Entry in Reports you can also easily add it to your dashboard by clicking on the Add to Dashboard button.
If you see an alert icon near the top of the dashboard, hover over it for more information - these are Administrative Alerts designed to help you keep your Untangle healthy.
Applications are little plugins that add functionality to your Untangle server - just like "apps" on an iPhone or Android device.
On the Apps tab you'll see the currently installed apps. Across the top there is a dropdown menu to switch to different Policies. Policies can be controlled via the Policy Manager app.
Apps can be installed by clicking the "Install Apps" button at the top. It will display the apps that can currently be installed. To install an app simply click on its icon. You can install as many apps at the same time as you like. After starting the installation of the desired apps you can click the "Done" button at the top to go back to the apps view.
Once installed the applications' settings can be configured by clicking on the Settings button or the icon of app, depending on the skin. Applications install with the suggested configuration which is the default settings and on/enabled in most cases. An application that is off/disabled will not process any network traffic. To enable a disabled application edit the settings and click "Enable" on the first tab inside the settings.
After clicking Settings, you will be presented with tabs for different settings sections, as well as typical buttons marked OK, Cancel and Apply. Apply saves any changes. OK saves any changes and closes the window. Cancel closes the window without saving settings. On the left hand side there is a Remove button which will remove the application from the current policy. The Help button will open the help for the tab currently being viewed.
Untangle has two types of Applications:
- Filter Applications All the Applications above the Services pane in the interface can have one instance per policy.
- Service Applications All the Applications below the Services pane are global and exist in all virtual racks.
Many networks only need one policy which means all traffic gets processed by the same apps and same configuration, but multiple policies (sometimes called "racks") are possible for bigger networks. For more information about running multiple racks check out the Policy Manager application.
To learn more about each application use the links below.
