The DynDns menu in the modem’s configuration does not seem to be active in firmware version “V12.C.24.05.08” of the Box 12.
A similar (or the same) issue existed already in version “V12.C.23.04.39”, which is documented in this topic:
The previous topic was a year ago, and it seems that it is not addressed yet, even though the feedback would have been brought to the attention of the technical people.
I had a phone conversation with the KPN support and nobody knew this as a flagged issue; it appeared as if there has been no report for it.
Is there any plan to fix this issue and enable this configuration or will it remain inactive?
If it is not working should it not at least be removed, not to confuse the user?
