Why Untangle for Windows?

Using Untangle for Windows Re-Router^TM Technology (Untangle for Windows), you can run an Untangle on any Windows XP machine on the network. Untangle will filter all the other machine's network traffic - just like a dedicated server but without the dedicated hardware!

Untangle for Windows is perfect for smaller networks.

• No new hardware required
• No network configuration
• Install is easy

In such a deployment, the Untangle truly becomes plug-and-play. Simply install the Untangle software on an existing PC or laptop that's running a supported operating system. The PC does not need to be located at the "edge" of the network.

How Does Untangle for Windows Work?

Untangle for Windows reroutes all inbound and outbound traffic (but not traffic between network clients) through the Untangle. Untangle uses its Re-Router^TM Technology to re-route traffic going to the internet through Untangle before it leaves the network and the same for incoming traffic.

Each network client stores information about the router/gateway. Untangle for Windows simply tells these clients that it is the gateway for the network. As a result, all traffic goes through to the Untangle, delivering the complete benefits of a dedicated Untangle Server to you with no dedicated hardware and no network reconfiguration.

Requirements

• Windows Platforms
• Network
• CPU/Memory/Hard Drive
• Switches

Windows Platforms

• Microsoft Windows XP Home Edition
• Microsoft Windows XP Professional Edition
• Microsoft Vista

Network

• 1 Network Card. Really, the Untangle for Windows can route traffic with only one network card! Untangle for Windows is specifically for this purpose. If your computer has more than one network card, then you must deploy the Untangle Server as a bridge or router and install Untangle Server using an ISO Image.

• Wired connection. Untangle for Windows requires a wired connection, as shown in Figure, Untangle Server as Re-Router^TM. You cannot deploy Untangle for Windows on a Windows XP computer that is connected to the network using a wireless network adapter. This limitation is related to how VMware Player bridges network adapters. However, you can have a wireless network and still have the Untangle Server protect that network.

CPU/Memory/Hard Drive

• CPU: 1.0 Ghz
• Memory: 2 GB
• Hard Drive: 20 GB

Switches

Untangle for Windows cannot operate in a network that uses advanced smart switches. Smart switches prevent Untangle for Windows from re-routing traffic. Advanced smart switches can be very expensive ($700 US) relative to retail switches (for example, most NetGear switches aren't advanced). Most of the time small offices do not use smart switches, so if your company is small, you're probably safe in assuming that your network doesn't have a smart switch.

If your switch is on the following list, then it's a smart switch.

• AT&T 2Wire 2700HG-B DSL Gateway
• Catalyst 4500 Series
• Catalyst 3750
• Catalyst 3560
• Linksys SPS224G4
• Juniper EX 3200 24P
• HP Procurve

Installing Untangle for Windows

You only need to install one Untangle for Windows on your network to protect and control your entire network. An Untangle includes a application for Anti-virus, along with many other applications. If you purchased a product like Symantec Anti-Virus, you'd need to install this software on all desktops in your company—not with Untangle. You only need one Untangle Server on one desktop.

Before You Begin: Preparing for your installation.

1. Using a network cable, connect the Windows computer to the network. Untangle for Windows must have a wired connection, not a wireless connection.

Troubleshooting Untangle for Windows Problems

Symptom	What's this mean?	What do I do?
Tried to launch the Untangle Client, but browser displays Failed to Connect error.	Untangle for Windows might not be running.	Start Untangle for Windows.
The Untangle for Windows icon is missing from my system tray.	In the system tray there are two options worth discussing: Stop and Quit. You might have selected Quit instead of Stop. Quit simply removes Untangle for Windows from your system tray.	To add the Untangle icon to your system tray, go to Start > Program Files > Untangle > Untangle.
The Untangle for Windows icon in my system tray indicates a status of Starting. Untangle for Windows has been in this state for over 10 minutes.	This is normal if you just finished an initial installation. Otherwise, it sounds like your Untangle Server cannot boot and is in an abnormal state.	Go to Start > Programs > VMware > VMware Console. Don't use this under any other conditions because this action results in an ungraceful shutdown. It will take several minutes before Untangle for Windows boots and indicates Running.
