When you're ready, pop in the CD and reboot the PC. It should boot from the
CD and start the installation wizard. After the install, the you'll go through
the Setup Wizard. You'll select the language, create a password, and register.
Plus you can use their nifty utility to help you identify the network cards.
You'll want to remember which one will hook to the Internet or existing router
(called the External interface) and which will connect to your switch/computers
(called the Internal interface). You'll also configure the External IP, Internal
network, and email server settings.
Once you're done with the Setup Wizard, you'll be taken to the Web-based
Untangle Client. There you can set up the features, called Apps, and access all
the server's configuration settings. By default, you should be able to bring up
the Untangle Client from any computer on the internal network by typing the IP
of the gateway into a Web browser, using HTTP or HTTPS. You can optionally
enable external administration, so you can manage the gateway via the Internet
or External interface: click Config > Administration > Enable External
Administration.
Modifying the rack
On the left side of the client, you'll see buttons for each of the Apps and
packages, where you can click them for more information. Plus you'll find a link
for a free download, free 14-day trial, or to purchase it.

Once you install an App, its added to the area on the right, that's designed
to look similar to a rack you'd find in a wiring closet. Going with the rack
look and feel, you can turn Apps on and off by clicking the power button. Plus
you can refer the status and statistics. To configure the feature, click the
App's Settings button.

We've installed the Untangle Gateway and configured the general settings. Now
you can fiddle with the different Apps and set up everything to your liking. If
