    How can I see which crypto is being used with Data Encryption Negotiation enabled on a site-to-site tunnel?

      @coreybrett You could try increasing the verbosity level of the OpenVPN logs and then check them. Default log level doesn't show much. This is just a guess. I have no idea if it actually tells you that in the log but I would hope so.

        I've set :

        So, no surprise, I see in the logs the same thing :

        2021-07-15 12:44:55.799700+02:00 openvpn 48505 GertjanHome/92.184.123.121:55566 Outgoing Data Channel: Cipher 'AES-256-GCM' initialized with 256 bit key

        I also saw the same thing on the client side - in the logs of my Phone..

        No "help me" PM's please. Use the forum, the community will thank you.
        Edit : and where are the logs ??
