this is why i am going crazy
try to assign the ip 2a02:8428:654:a301:7fd1:ba6f::/56 or the full 2a02:8428:654:a301:7fd1:ba6f:xxxxxxxxx to the bridge
nothing better, probably there is something broken on my ISP’s network. Before it worked with just the address in 302 :: 1/64 and nothing else.
The modem has also been changed, it is new.
it seems that there is no advertisement as if SLAAC is not working.
Sorry, I hope you solve the problem in short time.
Have a nice day.
Thanks again for spending time with me ! Hello Italy
