Enable IPv6 behind MikroTik

I have a Fritz!Box 7390 with IPv4 and IPv6 enabled and a /48 IPv6-prefix. Behind this Fritz!Box I have a MikroTik router for a second network. This MikroTik does NAT for IPv4. But I want also use IPv6 here.

The question is how can I enable IPv6 behind the Mikrotik router.

Install the IPv6 package on the Mikrotik and allocate some /64s from the /48.

I have found a example how to config IPv6 in my case http://rackerhacker.com/2012/01/11/native-ipv6-connectivity-in-mikrotiks-routeros/
I have done this but it still doesn’t work. I have a /64 add to my wan interface. Can I then ping from this interface with ipv6 to the world? Because I can’t ping. If this should be to work then I have something wrong with my /64 addresses….

[edit]
When I enable IPv6 DHCP client on the WAN port. The have I to get IPv6 addresses on than port (DHCP client), or not? But I keep on the message Status “searching…”

But when I replace the MikroTik by my Laptop I get a IPv4 and IPv6 addresses.

I don’t understand it anymore what going wrong here……

I have the same Problem. Do you find a solution for this issue?
