OpenVPN - Transparent mode

Even though this is not very useful, OpenVPN is able to establish a tunnel without encrypting the data inside it meaning that it is possible to read the data inside the tunnel.

Transparent tunnel:

If you want to secure the tunneled data, use the OpenVPN pre-shared key or SSL modes:

Encrypted tunnel:

It should be obvious that the OpenVPN transparent mode must be used only inside a secure network for testing.

Look at the case studies to find examples with OpenVPN in transparent mode.
