I just upgraded a RUT240 to the new firmware RUT2XX_R_00.01.11.1.
When configuring OpenVPN, I noticed that the option for uploading the HMAC authentication key is not present anymore after clicking "Additional HMAC authentication".
In the older firmware versions it was like this:
In the new version I cannot upload the HMAC authentication key and therefore the client is not connecting.
Is it a BUG?
