OpenVPN Client 2.6.6 Download the Last Version for Apple Devices

As a user of OpenVPN, you may have encountered issues with connecting to an OpenVPN server after upgrading your operating system or switching to a new device. One common issue is the removal of support for the BF-CBC cipher in the default configuration. This cipher was previously used as a fallback option, but it has been deprecated in newer versions of OpenVPN.

If you are experiencing issues with connecting to an OpenVPN server at work, you may need to enable the BF-CBC cipher manually. To do this, you will need to add the following lines to your OpenVPN configuration file:

data-ciphers AES-256-GCM:AES-128-GCM:BF-CBC

data-ciphers-fallback BF-CBC

These settings will allow you to use the BF-CBC cipher as a fallback option when connecting to an OpenVPN server. You can also specify that you want to support very old peers by adding the following line:

data-ciphers-fallback BF-CBC

This setting will ensure that your connection is compatible with older versions of OpenVPN.

It's worth noting that OpenVPN 2.5.0 and later versions have removed support for the BF-CBC cipher in their default configuration. This means that if you are using an older version of OpenVPN, you may need to upgrade to a newer version to take advantage of more secure ciphers.

In addition to enabling the BF-CBC cipher, you can also switch away from it and use a more secure cipher instead. To do this, you will need to add the following lines to your OpenVPN configuration file:

data-ciphers AES-256-GCM:AES-128-GCM

data-ciphers-fallback AES-256-GCM:AES-128-GCM

These settings will allow you to use the AES-256-GCM and AES-128-GCM ciphers as a fallback option when connecting to an OpenVPN server.

In conclusion, enabling the BF-CBC cipher in OpenVPN is a relatively simple process that can be achieved by adding specific lines to your OpenVPN configuration file. By following these steps, you should be able to connect to an OpenVPN server at work and take advantage of more secure ciphers.
