Yes.

wvhemel> (route to internal interface)

It seems you need to have default route for internet, too.

wvhemel> However, this:
wvhemel>  route add -inet6 default link-local-address-of-router%interface-of-the-host

wvhemel> gives an error, 'No address associated with hostname: bad value'.

Please replace link-local-address-of-router and interface-of-the-host
to your actuall address.

wvhemel> So it's good measure to make /64 subnets... That's the kind of thing I'd

Please refer RFC2373 (IPv6 Addressing Architecture) 2.5.7 Aggregatable
Global Unicast Addresses.
