Internet Sharing / NAT (IPv6)

I have two wlan devices (radio0, radio1 (and eth0 too)):
radio0 has an connection with my router (which give devices ipv6). radio1 should work as an access point.
eth0 should bring internet to my pc.
I followed https://wiki.archlinux.org/index.php/Internet_Share

How the hack do i get IPv6 working, because there is no NAT in ipv6.
Is the simplest way an tunnel? How would my dnsmasq need to be configured.

ip route                                     
default via 192.168.178.1 dev radio0
192.168.178.0/24 dev radio0  proto kernel  scope link  src 192.168.178.80
192.168.179.0/24 dev radio1  proto kernel  scope link  src 192.168.179.1
192.168.180.0/24 dev eth0  proto kernel  scope link  src 192.168.180.1

l made two diffrent nat's for radio0 and eth0, because as i tried to bridge them, to use only 192.168.179.1/24 speed dramaticly droped to 30kb/Sec ... Which is not okay.

I thought the whole point of IPv6 was to get rid of NAT altogether, and of public/private IPs, given the abundance of available IP addresses.

Re: Internet Sharing / NAT (IPv6)

yes, but for this working without an NAT, you have to bridge stuff. And wlan briding is only possible with WDS (4addr). This Standard supports only Security up to WPE, which is not that good here in Germany. Because there is an law, which says that your wlan  must be encrypted on the State of Art. (WPA / WPA2).

Hopefully IPv4 will not die that fast, else i am doomed.
