Thanks for all help, but I'm still facing problem. I know there aren't nat on ipv6, but making an analogy to ipv4, is the same symptom that a private network without nat. I'm receiving ip addr, but I can't have access to Internet.
I read some documentaries and videos on Youtube and did step by step without skipping steps.
Now I'm trying to use RB 3011 UiAS-RM with the last router board OS version.
Question: If I get a /64 network from my ISP can I also re-pass (advertise) as /64?
My config:
/interface bridge
add name=LAN
/interface ethernet
set [ find default-name=ether6 ] name=ether6-master
set [ find default-name=ether7 ] master-port=ether6-master
set [ find default-name=ether8 ] master-port=ether6-master
set [ find default-name=ether9 ] master-port=ether6-master
set [ find default-name=ether10 ] master-port=ether6-master

I'm receiving IPv6, m RB as set as default gateway, but I'm reaching internet.
