on my dorm's network there is native ipv6 support. After reading wiki articles and googling I got the following parts working:

  • List item
  • Router gets IPv6 address
  • Router can ping IPv6 addresses on the internet (like google etc.)
  • IPv6 addresses are distributed to my local network

But I can't ping any IPv6 addresses on the internet from my PC. Windows can resolve the IPv6 address of google but the ping ends in a timeout. Here is my config:

/etc/config/radvd

root@OpenWrt:~# cat /etc/config/radvd
config interface
        option interface        'lan'
        option AdvSendAdvert    1

        list client             ''
        option ignore           0

config prefix
        option interface        'lan'
        # If not specified, a non-link-local prefix of the interface is use
        option prefix           '2001:7c0:e701:4184::/64'
        option AdvOnLink        1
        option AdvAutonomous    1
        option AdvRouterAddr    0
        option ignore           0

        option interface        'lan'
        list prefix             '2001:7c0:e701:4184::/64'
        AdvRouteLifetime        'infinity'
        option ignore           0

config rdnss
        option interface        'lan'
        # If not specified, the link-local address of the interface is used
        option addr             '2001:7c0:e701:4184::1'
        option ignore           0

        option interface        'lan'
        list suffix               ''
        option ignore           1

/etc/config/firewall

What could be wrong?

Missing routing/firewall? My plan was to set up IPv6 without a firewall to see if it's working and set up the firewall later...

Something I recognized is that in the web interface "IPv6 WAN Status" is "Not Connected", but don't know if this is fully supported in the web interface. Thanks for your help....

Did your ISP actually delegate you a prefix? I can't seem to find any IPv6-specific configuration instructions for them. –  Michael Hampton Jan 15 '13 at 21:19
