Just because your router supports IPv6 doesn't mean it should open connections from the outside world. I'd expect all home routers to continue to default to "only outwards connections allowed" and let you specify open ports as you need them - exactly as they do now.

This is getting close to my point. If: 1) outbound only is going to be the default, and 2) most services already need 'man in the middle' (directly service at least) and 3) IPv6 is going to need to NAT to get to the legacy IPv4 addresses anyway

What advantage is IPv6 for most of my devices giving me?

[AndrewDucker]

IPv6 doesn't NAT to get to IPv4 addresses - you'll need to run both in parallell to get to IPv4 addresses, until everyone is switched over.

And the advantage is that when you _do_ want to go direct you aren't stuck with being behind NAT on your router and then another NAT at your ISP, and then possibly another NAT level, and then the same in reverse at the other end, so that it's possible at all.

And sure, it might not give _you_ anything you particularly care about. But when you find that you can't do something, because there are several layers of indirection between you and someone else, and now you need to run your own server in order to hook two machines to each other over the internet, then you'll wish IPv6 was available.

For the cases where you do want to allow inbound connections, enabling them becomes simple and reliable
