IPv6 connectivity of the external connection
The problems with IPv6 connectivity via the TU's external connection that occurred on September 11 have been permanently resolved since October 21 by a patch from the manufacturer.
Before that, intensive work was done to find a permanent solution. Due to the complexity of the problem, this took some time and, despite a workaround, repeatedly caused small disruptions in order to reproduce the error and provide the manufacturer with measurement data.
