Configuring IPv6 in Proxmox VE3

I’ve been googling for some articles and tutorials about IPv6 support in Proxmox VE3, but most of them didn’t explain it clearly, and some of them using language other than English, so, here is some fix for IPv6 inside Proxmox.
Configuring sysctl.conf

To apply the configuration, we can reboot the dedicated server or run # sysctl -p
For the IPv6, let’s assume that we got the following IPv6 allocation :

  • ┬áRouted IPv6 : 2a02:7900:1:1002::2/64
  • Gateway : 2a02:7900:1:1002::1

Add an IPv6 to your OpenVZ container

Install radvd for announcing your IPv6 range

Configure your /etc/radvd.conf, and we are using our whole IPv6 allocation here, so another IPv6 from our range will be announced.

Configure our /etc/network/interfaces to automatically load the routing when the dedicated server boot.

Now, we can login to the container or newly created OpenVZ VPS, and have a working IPv6 connection
