using HE TunnelBroker to provision VMs with IPv6 on a ipv4/ipv6 dual stack

Hello,

Has anyone achieved a dual stack of having the ability to use both ipv4 and ipv6 for provisioning VMs? I want to be able to provision vms with both and need to use tunnelbroker as my datacenter currently does not support ipv6 networking..

I added the configuration for ipv6 to the host (he-ipv6) however vmbr0 is configured for ipv4... is this correct?

ipv6.google.com is pingable.

What are the next steps?

This is my current configuration: (I have remitted IPs for security reasons)
auto lo
iface lo inet loopback

auto eno4
iface eno4 inet manual
post-up echo 1 > /proc/sys/net/ipv4/ip_forward
post-up echo 1 > /proc/sys/net/ipv4/conf/eno1/proxy_arp

iface eno1 inet manual

iface eno2 inet manual

iface eno3 inet manual

auto vmbr0
iface vmbr0 inet static
address xxx.xxx.xx.xxx
netmask 29
gateway xxx.xxx.xx.xxx
bridge-ports eno4
bridge-stp off
bridge-fd 0

auto he-ipv6
iface he-ipv6 inet6 v4tunnel
address 2001:xx:xxxx:xx::2
netmask 64
endpoint xx.xxx.x.xx
local xxx.xxx.xx.xxx
ttl 255
gateway 2001:xx:xxxx:xx::1

After the installation only the IPv4 is configured on the vmbr0. But OFC, this can be changed later on.

I don't understand, if IPv6 is already working. You might want to create a separate bridge for the IPv6 traffic and set the IPv6 address there. This way you can route your IPv6 traffic.
