Tunnelbroker.com & IPv6 Support on CentOS 6.8 (Final)

Hello there,
I was wondering if anybody got managed to run the IPv6 to IPv4 tunneling on CentOS 6.8 (Final). If anybody did it, please tell me exactly the steps you made it, because I already put the pistol on my night desk and more often I start staring at it ... Also any other IPv6 to IPv4 tunnel broker configuration will be appreciated. Thanks in advance.

ipv6 is currently not supported with CWP

This is the idea I have console to set it up and after I see it working to make an addon for it. Actually the addon is ready. Just the IPv6 settings for eth0 and sit0 which will be put in /etc/sysconfig/network-scripts/ifcfg-eth0 and /etc/sysconfig/network-scripts/ifcfg-sit0 have to be adjusted. But I still can`t figure it out how to make IPv6 tunnel to work on CentOS 6.8.
