Here is my Tunnel Configuartion in Router, 

interface Tunnel0
 description Hurricane Electric IPv6 Tunnel Broker
 no ip address
 ipv6 address 2001:470:18:417::2/64
 ipv6 enable
 tunnel source x.x.x.x //IPv4 source public IP
 tunnel destination x.x.x.x //IPv4 destination public IP
 tunnel mode ipv6ip

 I have disabled the IPv4 from network interface and using only IPv6 address. I tried to access ipv6.google.com in my browser and it is not loading. Any websites even it is ipv4 it is not loading. I could not find what is the problem in my router. but if I enabled the IPv4 in my LAN client it forwarding all IPv6 traffic via ipv4. (4to6 tunnel).

 

1. I tried with IPv6 alone but it is not forwarding my internet request. What else I am missing?

2. My BRAS has a 6 to 4 tunnel, is the configuration correct?. If yes, is it possible that i can reach internet via IPv6 only in my topology? If no, then kindly help me.
