Hi Albert, Thanks for your suggestion.
I believe it is not in the slaac mode and in dhcpv6 only. I confirmed with below things. 1) Router advertise, solicit, request things are happening while every client getting connected. 2) The bit Managed address configuration is set. Checked through wireshark. It will be set in DHCPv6 only and not for slaac. If you believe still it is in slaac mode, Please tell the config changes to make dnsmasq run as a dhcpv6 server.
