OpenBSD doesn't support IPv6 autoconf on routers (i.e if forwarding

which said that a router cannot do autoconf. There is a newer RFC which
clears this up but OpenBSD doesn't support it yet:
http://tools.ietf.org/html/rfc6204
However, using a global prefix on your WAN link is usually not a
hard requirement since link-local addresses are sufficient for this.
Try setting a default route that points to pppoe0:
!/sbin/route add -inet6 default -ifp pppoe0 fe80::
Your router should now be able to reach the IPv6 internet.
Thanks Stefan for the good explanation and the setting! I'll try it out
in a bit.
Once this works you need to get your LAN connected, too.
Did you get a static IPv6 prefix from your ISP for your LAN?
Unfortunately it's all dynamic. M-Net used to be a friend about static
IP addresses (which allowed me a tunnel to sixxs before), but they have
turned against giving out static, whether v4 or v6. If I remember right
they assign a /64 for the link, and give out a /48 somehow which is
dynamic too.
You would need a DHCPv6-PD capable DHCPv6 client such as wide-dhcpv6.
