> In short the things I have done:
>
> A) I generated a IPv6 Prefix based on the computers MAC Address
> (http://www.kame.net/~suz/gen-ula.html generated fd43:b2bc:bc95::/64 )
>
> B) I tried to enable forwarding from the command line using the
> following
> statement:
> netsh interface ipv6 set interface interface="Local Area Connection"
> advertise=enabled
> This step already seems to fail. If I run
> netsh interface ipv6 show interface interface="Local Area Connection"
> afterwards i get the following output:
