public root server with /64 IPv6 & my local home inet

Hey all,

I am having a public reachable root server with its own /64 IPv6 block ready 
and at home still IPv4 but a WRT54GL with a fresh OpenWRT (IPv6-capable) 
installed.

Now I want to bridge the IPv6 network from my root server to use this 64bit 
block *locally* leaving the primary address at the public root server, and 
distribut the remaining at my home's computers.

I hope I described my goal just right, but currently I'm a little 
overquestions in what the right way to go would be.

AFAIK, I am in no need for a tunnel broker because I am having already an IPv6 
block, but I need to set up a virtual network that connect my root server with 
my wrt54gl router that in forwards all IPv6 traffic behind it and the root 
server.

From my point of view, radvd should *ideally* be installed on the root server, 
but this is where it ends for me - I just hope I do not need too many layering 
tools like OpenVPN to achieve this goal.

What can I do?

Regards,
Christian Parpart.
