Using Custom OpenVPN Binaries
THE FEATURE DESCRIBED ON THIS PAGE IS AVAILABLE ONLY IN TUNNELBLICK 3.8.2beta04 AND HIGHER
Although the Tunnelblick application includes several OpenVPN binaries, Tunnelblick 3.8.2beta04 adds the ability to use OpenVPN binaries that are not included in Tunnelblick.
How To Use Your Own OpenVPN Binary in Tunnelblick
1) You need an OpenVPN binary. If your configurations use the "down-root" plugin, you need a binary of that, too.
The files must have exactly the following names: "openvpn" and "openvpn-down-root.so".
2) Create a folder named "Openvpn" on your Desktop or some other convenient place.
3) In that folder, create a subfolder named "openvpn-VVV-NNN-SSS", where
So "openvpn-2.5_git_57623b4-openssl-1.0.2u_Without_scramble_patch" will be displayed as "OpenVPN 2.5 git 57623b4 OpenSSL 1.0.2u Without scramble patch"
4) Move or copy your "openvpn" binary into the subfolder (and the "openvpn-down-root.so" binary, if needed).
5) Create similarly-named subfolders for each OpenVPN binary you wish to use and copy the binaries into them.
7) Move or copy the "Openvpn" folder to /Library/Application Support/Tunnelblick. (You will be asked by Finder for a computer administrator's authorization.)
8) Quit Tunnelblick (if it is running) and launch it. If you did not set the ownership and permissions in step 6 above (or you set them incorrectly), Tunnelblick will ask for administrator authorization to secure Tunnelblick and will then set the ownership and permissions for you.
You're done! You can specify which OpenVPN/SSL combination to use for each configuration in the "Settings" tab of Tunnelblick's "VPN Details" window. Note that changes made there are applied to all of the configurations selected on the left side of the window.
