--- Comment #14 from John Hay <john@sanren.ac.za> ---
Looking at your tcpdumps, one can see that the packets are correctly transl=
ated
before being transmitted, so that part is working. The problem is that beca=
use
the vtnet0 interface is an ethernet like interface, the kernel is only goin=
g to
accept or respond to the addresses that are configured on the interface. Th=
at
is why you see the router sending neighbor solicitation messages, but your =
vm
does not respond to them. That is not a ipfw or nptv6 problem, but more a
kernel networking thing.

If you can get another /64 from vultr that they will route to you, you can
configure that on lo0 and then let nptv6 use that for the external prefix.

Where I have seen nptv6 work with a /64 ipv6 address that is configured on =
the
external interface is with pppoe setups, but ppp and tun interfaces behave
differently, they do not need neighbor solicitations, packets are just sent.

If you only have a few devices, you might be able to configure proxy ndp for
their external addresses, but I have not tried that.
