Setting up OpenVPN on Mac OS X 10.4 (client section)

Setting up OpenVPN using the free Tunnelblick software. This software isn’t as easy to set up as the $9 Viscosity, but it works the same once it’s configured.

Download the VPN software


Download the client from

Tunnelblick_(version).dmg will download. Double click on that file to mount the disk image.

Install Tunnelblick


Drag the file to your Applications folder. You can do this in that window by clicking and dragging. Do not launch the application yet.

Distributing the client via email


Follow the link in the email message you recieved, or download the attachment in the email from the VPN admnistrator.

Click here… or copy and paste into your web browser.

If you got a message from your administrator with a file called attached, skip ahead to "Download the VPN software."

Secure Connection Failed


If you get this screen because you are using Firefox, visit to learn how to get around this.

Note – you may not see this warning in other browsers, so you can ignore this step if you don’t have the problem.

Downloading the configuation file


For Mac users, click on the Configuration Files link.

A file called "" will download, and may automatically decompress to a folder called "untangle-vpn." If it does not do this automatically, double click on the to make this happen.

Installing the configuration files


This step may be a bit tricky, so pay attention.

In the root level of your hard drive (what you see if you click on Macintosh HD on your desktop), there is a folder called Library. Open this folder and create a folder called "openvpn." This Library folder IS NOT in your User’s Home folder – that’s where you see Desktop, Documents, Downloads, Movies, Music, Pictures, etc.

Then drag contents of the untangle-vpn folder to this folder, so it looks like this. The outlined portion is shown just to show you the location of the folders.

Very important – inside the folder called untangle-vpn IS ANOTHER folder called untangle-vpn. Confusing, I know, but I didn’t write it! Make sure you drag the contents of the first untangle-vpn folder, not the inner one. You should drag the files as shown in the picture above.

Launch Tunnelblick


Launch the Tunnelblick application from your Applications folder. If you can’t find the Applications folder, use the Go menu in the Finder’s menu bar.

You will get a warning message the first time that looks like the next step.

Welcome to OpenVPN


If you followed the installation steps above correctly, click Continue.

Checking for updates


Tunnelblick checks for updates automatically, if you allow it. It’s a good idea to "Check Automatically" because it only gets better with each new release.

Tunnelblick’s icon


The only interface for Tunnelblick is this icon, which will appear in your menubar at the top of your screen.

Click on the icon to show this menu


The drop down box will show you a list of connections. It may not be nameed openvpn, but it may show something different. That’s ok, release them mouse button on the connection you want to make.

Authorize the connection


The first time you connect, you’ll be asked for your computer account password. Enter it and press OK.

Successful connection


If all goes well, you’ll see the "light at the end of the tunnel!" – not the subtle changes in the icon indicating the connection.

Connecting to remote file servers


Once you have made the connection, head back to the Go menu and choose Connect to Server…

Connect to Server


The main difference between connecting to a server via a VPN and a local connection is that VPN connections don’t pass the Bonjour names of servers or show up at all – so you have to know the IP address or name of your intended connection. Enter the IP address of the server you want to connect to, and press Connect.

Remote Printers


You can also print to remote printers. In System Preferences, choose Print & Fax, then hit the + to add the printer. The thing to remember hereis that the printer must be accessible via an IP address – so USB connected printers won’t work. Note – these screenshots are from 10.5, but the printer setup is nearly identical, but don’t expect to see exactly what you see here if you are running 10.4.

Adding an IP Printer


Choose IP from the icons on the top. Then enter the Address of the printer in that field. Most of the time you can leave Queue empty. And as long as you have the printer drivers installed on your machine, the computer will find the proper settings files. The IP address will automatically show in the Name field, but feel free to change the name of the printer to something easily identifyable.

REMEMBER: You must be connected to the VPN in order to print to a remote printer!!! IT’s probably best not to make this new printer the default printer unless you plan on being connected to the VPN all of the time.
