My router is connected via Ethernet (Fibre Media Converter). The Internet connection is established via PPPOE. But if the provider changes the IP address or I restart the PPPOE connection. Then the connection is (often) not re-established. See the logs. Only unplugging the Ethernet connection leads to a new connection and it works. What could be the cause?
One more information: The Internet is a pure IPv6 network. The IP4 address is obtained via IPV6 (dual stack). It is running. Both IP addresses are accessible. My Router is Kennetic Hero. With version 4.1.7. I tested with 4.2 too. The same problem.
