Hi folks,

just wanna seek your assistance with regards to the tunnel configuration on windows 7. my situation goes like this, i can monitor that the tunnel is up but i can't ping ipv6.google.com and also my default ipv6 gateway.

below is the config

netsh interface teredo set state disabled
netsh interface ipv6 add v6v4tunnel IP6Tunnel 192.168.3.3 216.218.221.6
netsh interface ipv6 add address IP6Tunnel 2001:470:18:c0e::2
netsh interface ipv6 add route ::/0 IP6Tunnel 2001:470:18:c0e::1
