Do I understand that you attempt to provide a single IPv4 address 1:1
with a an internal IPv6 address? (NAT vs NAPT)

Yes. Stateless NAT64. http://tools.ietf.org/html/rfc6144#section-3.2.1

Can you tell me what your expiry time is for reclaiming the IPv4 address?

2 hours. However, anything above 5 minutes will yield the same result on today's Internet. And 5 minutes is too short.

Would IPv6 ping'ing the internal device help?

Hmm? Help with what? I'm not sure I understand you.
