shouldn't you just configure routing instead of using proxy_ndp?
without these the following is not possible, -> Destination host unreachable
ping6 homeprefix::1 ping6 tunnelprefix::2 ping6 tunnelprefix::1 (the sit1 device of the server itself)
If I understand correctly your hoster has assigned you 3 subnetworks but it is not routing them to your VPS, it just expects your VPS to use them on its interface. In this case, yes, you need proxy_ndp, and if there is a way to avoid enumerating each IP I would be interested to know.
If instead tunnelprefix and homeprefix were just externally routed to serverprefix::1 everything would be simpler, but that is not under your control, I assume.
