I tried this a few years ago and fell flat on my face due to the lack of NAT64 and DNS64 support. Reading through docs now, it looks like unbound has a DNS64 module, and NAT64 is baked into ipfw. Waving a hand at bug-hunting and lamentations over the inertia of embedded systems designers, has it really become this easy to turn up an IPv6-only site?
