PPPoE: IPv6: Where is the (Stateless) DHCPv6 server?

Question

Using the latest 3.9 alpha 4, PPPoE, IPv6 component installed and enabled …

IPv6 works great on my clients. However, in Apple macOS, I do not see a DNS server via IPv6, just IPv4. Therefore, I opened Wireshark and filtered for icmpv6.type == 134 || dhcpv6. The router advertisement (RA) has the flag Other set. Therefore, LAN clients ask the (stateless) DHCPv6 server for the DNSv6 server. And that server does not answer. Is the RA simply wrong and there should be not DHCPv6 server. Or is the DHCPv6 server simply not running?

Yes, I know, from the user experience, this is no issue because I can do IPv6 (DNS-AAAA) even via the existing DNSv4. However, my clients search for that DHCPv6 server all day long. And this is not the way it was designed. Either the Other flag is set incorrectly. Or a DHCPv6 server should answer.

Thanks for the report. I can confirm that we lost this functionality by accident. Will be fixed in future versions. NDM-1975 NDM-2363.
