Hello David, Thanks for the time that you spent on explaining basic concepts to me.

Thanks David for highlighting the above. When you wrote --tls-auth key, you were referring to the server-side --tls-auth key, which is owned and kept by the VPN provider, yes? > > So if the VPN provider uses a proper community based version and not > their own AES-GCM implementation, this should work quite fine out of the > box with v2.4. My VPN provider has its own AES-GCM implementation and has even offered me the source code to check for security risks. As I am no expert in OpenVPN technologies and cryptography, I declined to use their software. Regards.
