I am struggling a bit on how to equip my LXC configuration with IPv6 currently.
What's the setup?

* Ubuntu 16.04 LTS
* LXC2-beta from the Ubuntu PPA's (feature IPv6 connectivity)
* I use a [netcup](http://www.netcup-wiki.de/wiki/Zus%C3%A4tzliche_IP_Adresse_konfigurieren#IPv6) IPv6 setup
* Currently IPv4 is routed via DNAT over eth0, work's fine (**NO BRIDGE**)
* My host machine gots working IPv6 at prefix::1/64

I've read up a really long list of literature about IPv6 and how to solve this problem with several virtual machines, but couldn't come to a working, sane setup yet.
So, what'd do I do now to get my LXC machines connected with IPv6?

1. Enable IPv6 net forwarding
2. Either
	* Assign each container a valid address in the /64 subnet (this does not work for me?)
	* Host a gateway at prefix::1 and use (e.g) radvd for automagic configuration (didn't work either)
