Hello,
can anybody answer the question, if the currently used implementation of OpenVPN on RouterOS is using TLS(1.0, 1.1, 1.2) or SSL?
I am currently using v6.27 on all my devices in the network. Does this change with newer versions?
Further explanation:
As the newer Client Versions default to TLS while connecting you now have to specify tls-cipher DEFAULT in these clients to connect successfully. This behaviour led me to guess that the current implementation (while still lacking UDP support 
) only supports SSL on the Data Channel, but TLS seems to be partly supported on the control channel, which is kind of weird or the logs are wrong.
My concerns are security based because SSL is known to be flawed by now.
Hoping for answers
