 If you have a Kimsufi Dedicated, you got a full /64 not just /128 which is a single IP, lets use it.
+Next, we need to add IPv6 to our vmbr2, which the VM should be connected to.
-First we need to enable Forwarding on the Node:
+  iface vmbr2 inet6 static
+       address 2601:xxxx:xx:xxx::2
+       netmask 64
+       bridge_ports none
+       bridge_stp off
+       bridge_fd 0
+       post-up echo 1 > /proc/sys/net/ipv6/conf/all/proxy_ndp
+       post-up echo 1 > /proc/sys/net/ipv6/conf/all/forwarding
+       post-up echo 1 > /proc/sys/net/ipv6/conf/default/forwarding
+       post-up /sbin/ip -f inet6 neigh add proxy 2601:xxxx:xx:xxx::2 dev vmbr2
+       post-up /sbin/ip -f inet6 neigh add proxy 2601:xxxx:xx:xxx::3 dev vmbr0
+       post-up /sbin/ip -f inet6 route add 2601:xxxx:xx:xxx::3 dev vmbr2
+The next thing you need to do, restart your network on your Dedi with:
+   service networking restart
+Now Login into your VM and add this to your /etc/network/interfaces:
-  net.ipv6.conf.all.forwarding = 1
+  iface eth0 inet6 static
-  net.ipv6.conf.all.proxy_ndp = 1
+       address 2601:xxxx:xx:xxx::3
-  net.ipv6.bindv6only = 1
+       netmask 64
+       gateway 2601:xxxx:xx:xxx::2
+Restart your Networking on the VM:
+   service networking restart
+If it dosen't respond after a while, try to Reboot your VM over Proxmox.
+Now we still need to add IPv6 DNS Server to our /etc/resolv.conf:
+:4860:4860::8888
+:4860:4860::8844
+These are the IPv6 Nameservers from Google but you can use different ones.
+If you run:
+  ping6 google.com
+You should get a response and you should be able to reach your VM under this IPv6 which you configured earlier.
