I'm trying to get IPv6 working, with a he tunnel.
I managed to get it working, for the most part. I followed documentation that I found here and here.

From the router, I can ping6 to the outside world.
Code:

router ~ # ping6 ipv6.google.com
PING ipv6.google.com(2a00:1450:8004::93) 56 data bytes
64 bytes from 2a00:1450:8004::93: icmp_seq=1 ttl=55 time=32.3 ms
64 bytes from 2a00:1450:8004::93: icmp_seq=2 ttl=55 time=27.8 ms
64 bytes from 2a00:1450:8004::93: icmp_seq=3 ttl=55 time=27.0 ms

I also can ping6 the clients, from the router. The other way around also works, I can ping6 the router, from the clients.

But I can't ping6 the outside world from the clients.

I have forwarding set to 1.
Code:

router ~ # cat /proc/sys/net/ipv6/conf/all/forwarding
1

Even with ip6tables set to accept all, it still doesn't work.

Somehow, forwarding doesn't work. Does anyone have an idea what might be wrong?

the trival assumption would be to check the routing table of the clients...

I noticed that both bind and postfix where not listening for IPv6 packages. So I changed the configuration and restarted the services. After this everything worked fine.

My guess is that bind was the problem.

Anyway, it's all working great now. :D
