Tunnelblick
Tunnelblick is a free, open source graphic user interface for OpenVPN on OS X. It provides easy control of OpenVPN client and/or server connections.
It comes as a ready-to-use application with all necessary binaries and drivers (including OpenVPN, easy-rsa, and tun/tap drivers). No additional installation is necessary -- just add your configuration and encryption information.
To use Tunnelblick you need access to a VPN server -- your computer is one end of the tunnel and the VPN server is the other end. For more information, see Getting VPN Service.

What's New
Version 3.4beta24:
- Includes OpenVPN 2.3.3 (as well as 2.2.1 and 2.3.2).
- Adds additional security checking of programs that Tunnelblick runs as root.
- Moves the 'Copy Diagnostic Info to Clipboard' to the main part of the 'VPN Details…' window.
- Adds a 'quit' command for AppleScript which terminates Tunnelblick properly so it is not launched at the next login.
- When 'sanitizing' a configuration file for 'Examine OpenVPN Configuration File' and 'Copy Diagnostic Info to Clipboard', Tunnelblick strips lines that appear between lines that contain '-----BEGIN' and '-----END' (even in comments). (This strips certificates and keys created by Open Access.)
- On OS X 10.6.8 and higher when using OpenVPN 2.3.3 and higher in a TUN configuration, Tunnelblick no longer automatically loads the tunnelblick tun kernel extension (kext). In this situation, OpenVPN will use the UTUN device driver built into OS X.
- Warns user if the system clock is not set correctly.
- Checks Tunnelblick preference files for errors.
- Changes words for 'In:' and 'Out:' in Russian.
- Adds additional information to a warning message about LSSharedFileListItemResolve returning an error.
- Fixes a problem that caused the initial notification window to remain visible even when the pointer moved away from the Tunnelblick icon.
- Fixes a problem that could cause loss of embedded certificates and/or keys when editing a configuration file.
- Fixes problems that sometimes caused the 'Load tun' and 'Load tap' settings to be ignored.
- Fixes a problem which sometimes displayed an incomplete window title for the 'VPN Details…' window in languages other than English.
- Fixes a problem which sometimes caused a crash.
- Fixes a small memory leak.

When it was good, it was really good. But since Tunnelblick is still in beta - for several months now, I had to move on. So I paid for and now use Viscosity - which works really well and has regular updates which are not beta. I doubt I would need to move back to Tunnelblick.

Keep in mind that I'm using a MBP i7 with a fresh install.
1. I had multiple disconnects for no reason what so ever, something I never experienced with Viscosity.
2. Every time I get disconnected I have to quit and restart tunnelblick for it to work again.
3. For some odd reason, every now and then, it leaves an openvpn process running in the background and tunnelblick gives me a message that it cannot recognize an openvpn process that is running and unless I terminate the process manually I cannot access the vpn server although tunnelblick shows that I'm connected.
It is good for what it is but for mission critical vpn access you should really consider something else.

If using an opensource solution, I prefer to use freewares on both client and server ends. Other clients on osx are good as well, but I don't think it's a good idea to charge customers for enhanced features of a free solution.

Careful...Mac OS X has enhanced features of a free solution, FreeBSD and other free open source components. I hope you think it's OK to pay for it! :)

I use tunnelblick with a paid VPN service and so far it has worked perfectly but the other day I noticed that my ip was exposed at some point because the connection dropped! How can I prevent the connection from dropping? Alternatively how can I make certain apps like Transmission, Sparrow or Chrome forcequit or refuse to work if I am not connected?

I'm running 10.5 on a MBP, clean install. Worked fine under 10.4.
Anyone else experiencing this under 10.5?
