Well, we don't know how to you configure your IPv6 router in manual. So
you'd better show us the information like your manual scripts if you
want to give more correct advices ;;

Actually i can understand the your crazy struggling.

Do you have native IPv6 addresses? If you do, i am proud of you. Anyway
you need to have a look IPv6 section of FreeBSD Handbook, rtadvd(8) and
rtadvd.conf(5). It will give you help. And you need to study IPv6 stuff
because it is not as easy as it seems, AFAIK. I mean you can solve your
matters if you study more.

Sincerely,
