I currently have a server with an IPv6 block, one IPv4 address, and a /30 block. The server is running multiple virtual machines via KVM virtualization through ProxMox 4 beta.
 
The provider I have does not have the best network. Therefore, it has been a nightmare to set up IPv6 from them. I have decided to get a tunnel from HE, which works fine for one VM. 
 
Here is the tunnel information from HE:

Server IPv4 Address:216.66.84.42
Server IPv6 Address:2001:470:1f12:6d7::1/64
Client IPv4 Address:37.187.88.221
Client IPv6 Address: 

Here is the output of /etc/network/interfaces:

# The loopback network interface
auto lo
iface lo inet loopback

# for Routing
auto vmbr1
iface vmbr1 inet6 static
        address 2001:470:1f13:6d7::1
        netmask 64
        post-up /etc/pve/kvm-networking.sh
        bridge_ports none
        bridge_stp off
        bridge_fd 0

auto vmbr0

        address 37.187.88.221

        gateway 37.187.88.254

        bridge_stp off
        bridge_fd 0


auto he-ipv6
iface he-ipv6 inet6 v4tunnel
        address 2001:470:1f12:6d7::2
        netmask 64
        endpoint 216.66.84.42
        local 37.187.88.221
        ttl 255
        gateway 2001:470:1f12:6d7::1

Here is the output from a working VM:

Currently, I have a bridged IPv4 connection that is bridged to the eth0 port, which works as long as I can assign MACs to each IP. Since I cannot assign a MAC to each IPv6 address, I cannot bridge it. Routing didn't work, so I tried a tunnel through HE. I have radvd installed and set to broadcast RAs through vmbr1, which the IPv6 only machines are bridged to. This works on one machine, but all the others fail to link.

 

The VMs have the exact same settings (including DNS) and do not work. I am unable to connect to them via RDP. I have used VNC to access them and the settings are a match, except the address. Any ideas why this wouldn't work?
