HE IPv6 tunnel dividing /48 to /64's on Proxmox

[Qian Chen]

I'm playing with Hurricane Electric's IPv6 tunnelbroker and am running Proxmox with a hardware node and multiple vms. Now I managed to allocate IPv6 addresses from my /64 pool to the vms. Here is how I did it:

On Hardware Node:

auto he-ipv6
    iface he-ipv6 inet6 v4tunnel
           address 2001:xxxx:xxxx:xxxx::2
           netmask 64
           endpoint endpoint_ipv4
           local local_ipv4
           ttl 255
           gateway 2001:xxxx:xxxx:xxxx::1

    iface vmbr0 inet6 static
           address 2001:xxxx:xxxy:xxxx::1
           netmask 64
           gateway 2001:xxxx:xxxx:xxxx::2

On VM:

iface eth0 inet6 static
        address 2001:xxxx:xxxy:xxxx::2
        netmask 64
        gateway 2001:xxxx:xxxy:xxxx::1

I also requested a /48 for my tunnel. Now if I want to allocate a /64 to each of the vm from my /48 block, should I create a bridge on the hardware node for each /64?

Hello Elgs Qian Chen

I'm playing with Hurricane Electric's IPv6 tunnelbroker and am running Proxmox with a hardware node and multiple vms. Now I managed to allocate IPv6 addresses from my /64 pool to the vms. Here is how I did it:

On Hardware Node:

auto he-ipv6
    iface he-ipv6 inet6 v4tunnel
           address 2001:xxxx:xxxx:xxxx::2
           netmask 64
           endpoint endpoint_ipv4
           local local_ipv4
           ttl 255
           gateway 2001:xxxx:xxxx:xxxx::1

    iface vmbr0 inet6 static
           address 2001:xxxx:xxxy:xxxx::1
           netmask 64
           gateway 2001:xxxx:xxxx:xxxx::2

On VM:

iface eth0 inet6 static
        address 2001:xxxx:xxxy:xxxx::2
        netmask 64
        gateway 2001:xxxx:xxxy:xxxx::1

I also requested a /48 for my tunnel. Now if I want to allocate a /64 to each of the vm from my /48 block, should I create a bridge on the hardware node for each /64?

Do you mean to assign /64 addresses to the existing /48 (virtual) LAN? In this case you can use the same bridge/NICs.

You can assign as many addresses as you like to one NIC or bridge.

If you think I have misunderstood something give more details about your request (which VMs / host should get which address (in the form xxxy:xxxx as above) )


Kind regards

Thanks for the reply Mr.Holmes.I have a routable /48. I want to assign each of my virtual machines with a /64 from my /48.

This is to much, you just need a /64 for all your VM and need only to assign a /128 to each VM.
You can divide your /48 this way: Assign a /64 to each proxmox node and assign /128 to each vm inside the proxmox node. Unless you are a big ISP, you will have plenty of /64 and /128 left.
