No router solicitations seen, going out from my host on which i ran Wireshark. So seem really pointing to a local issue on my Debian machine. The only IPv6 prefix on the interface was the link-local. > What manages the interface ?

The interface is configured in /etc/network/interfaces.d/, so NetworkManager is out of the game. At the time the issue was present, I missed to check /proc, however nothing changed and AFAICS everything necessary is enabled. There is also no filtering between the host and the router. > Did you see the message saying that no IPv6 routers were found ? Nothing like that. That's actuall I hoped to see. So essentialy that's what I'm looking for. Maybe a /proc or /sys entry to be modified to increase the kernel logging for the SLAAC process. Or maybe a kernel parameter set at boot..... Thanks - Alex
