IPv6 issue on Windows Server 2012 R2 with Hyper-V using static IPv6.

[myhken]

Hello.

Dedicated server from Hetzner, running Windows Server 2012 R2 with Hyper-V

Now I'm working on getting IPv6 to work properly. It works great on my main server. It works great on my Windows VM. It will not work in Linux, just local on the server, not from the internet.

I have put some xxx to mask my IP. On the pictures I have hide them.

My IPv6 settings is: Main IP 2a01:4f8:xxx:xxxx:: /64 Gateway: fe80::1 DNS: ffff:ffff:ffff:ffff::

First, my Windows VM created in Hyper-V:

The network IPv6 settings



I can ping the server from my home computer, like I also can ping the main server.



I can connect to the VM (and main server) with etc RDC using the IPv6 address. all is working great.

Then, the Linux VM.

I'm using the following setup:

/etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0

BOOTPROTO=static

ONBOOT=yes

HWADDR=00:15:5D:89:48:06

TYPE=Ethernet

UUID=d5b0ef67-db19-4d05-9adc-b70958ce36e6

NM_CONTROLLED=yes

IPV6INIT=yes

IPV6ADDR=2a01:4f8:xxx:xxxx:0000:0000:0000:0005

IPV6_DEFAULTGW=fe80::1

/etc/sysconfig/network

NETWORKING=yes

NETWORKING_IPV6=yes

HOSTNAME=xxxxxxxx

ifconfig

eth0 Link encap:Ethernet

HWaddr 00:15:5D:89:48:06 inet6 addr: fe80::215:5dff:fe89:4806/64 Scope:Link

From the server I can ping the VM and I can use SSH to login, everything looks fine:

try using Google DNS (2001:4860:4860::8888 and 2001:4860:4860::8844) if that fixes it then try using the DNS of your choice.

in the eth0 file I used DNS1 and DNS2 with your DNS. Then I took at /etc/init.d/network restart

Then I get this error, and still no ping to the outside:

[root@xxxxxxx ~]# /etc/init.d/network restart

Shutting down interface eth0: [ OK ]

Shutting down loopback interface: [ OK ]

Bringing up loopback interface: [ OK ]

Bringing up interface eth0: ERROR : [ipv6_set_default_route] Given IPv6 default gateway 'fe80::1' is link-local, but no scope or gateway device is specified [ OK ]

[root@xxxxxxx ~]# ping6 ipv6.google.com

unknown host

What are I'm missing. Why can't I connect to the world with this VM? It has no internet connection, because I can't ping anything inside the VM either. And I can't ping it from the outside, just from the main server.

Anybody that can help me?
