Wanted to thank to everyone involved in this thread.
Changed my ISP and IPv6 was very flaky. Old ISP was fine, new not. Both more or less the same with PPPoE and DualStack.
A week of testing, restored configs, started over on a second unit with a fresh installation, nothing worked. Using a router with tomato64 worked like a charm, no ISP issue. Suspected a misconfiguration on my side, found nothing.
Began questioning myself, my life and the universe.
Well, enabling Router Advertisements did help, I don't even know why I tried this.
And after discovering this thread, I set RA MTU in Dnsmasq DNS & DHCP in my IPv6 range to 1492 and everything is fine.
Thanks.
