Your home network uses addresses in the 2001:470:8:238::/64 address
space.  So, your Ethernet card attached to the home network would get
2001:470:8:238::1 as an address, statically assigned, at least the way
that I have done my network.  Your HE virtual interface uses
2001:470:7:238::2 as its address.

Now, on the system that has the HE interface, you use 2001:470:7:238::1
as the default gateway.

On other hosts on your home network, if you're running radvd, you'll use
a link local address; that's the address that radvd will send when it
does its router advertisements.  You'll need IPv6 forwarding turned on
on your box connected to HE, because it will function as a router.  You
would also do any firewalling on that host.

Does that answer your question?

The radvd configuration would look like this:

interface eth0 {
	AdvSendAdvert on;
	MaxRtrAdvInterval 60;
	MinRtrAdvInterval 30;

	prefix 2001:470:8:238::0/64 {
		AdvOnLink on;
		AdvAutonomous on;
	};
};

Your hosts on the network will automatically set a default gateway and
routes and all of that from the RA it receives, which can take up to 60
seconds after the machine boots with that configuration.
