Hello,

normally I use for OpenVPN tls-auth a static key.
client: tls-auth static.key 1
server: tls-auth static.key 0

When I use a Mikrotik as client it is not possible to specify a static key.

Is this a security risk when the tls-auth runs without encryption?

I have the same problem. Has you the answer?

AFAIK there is no TLS-Auth option in OpenVPN implementation with routeros.

IMHO without TLS-Auth the device is more vulnerable to DOS-Attacks, reducing availability of the service and consuming more resources.

Maybe in one of the next releases.
