Does miniupnp support NAT66?
I have a dual stack connection with a private ipv4 address behind double NAT (that makes it useless for miniupnp), a global dynamic ipv6 address on my router and the rest of a local net is behind the NAT.
I would like to use my ipv6 address with miniupnp but it seems that configuration is unsupported. |

This configuration is unsupported by UPnP IGD.
What's the point of NAT66 anyway ?

To keep lan addresses independent from the provider prefix delegation, to have predictable lan addresses. |

Well with IPv6 you can easily have a ULA address for LAN and a global address if you need to be reachable from the outside world.
Even if you are given only a /64 you have plenty of addresses to use for that usage

And with NAT you can have local addresses and global reachability at once.

I'm new into ipv6 and may not know how to do some things right, but I don't like an idea that provider controls the lan addresses. I want to have a barrier between wan and lan. One public ip is just enough for my needs (and for alot of home lans either), I don't need /64. |

Of course the provider doesn't control the LAN addresses. It gives you a public /64 : There is no such thing as having only one address with IPv6, the minimum is a /64.
If you choose not to use them but instead do complicated things with NAT, that's your problem.

One of the features of IPv6 is to have multiple addresses depending on the usage. One for the LAN, one for the internet, etc.
