My container has the following fixed IP address settings:
As you can see I set the prefix + the Interface ID. In my case "2003:xxx::8". But this works only if my IPv6 prefix does not change, so after an internet reconnect my provider assigns a different IPv6 prefix and my container is not reachable anymore.
I tried to use this, but it does not work:
192.168.178, ::8
How could I solve this?
