Can't access ipv6 internet on client
« on: May 13, 2013, 02:15:21 PM »

I installed the tunnel on the server. From there i can visit IPv6 only sites.
Then i went ahead to enable forwarding in sysctl, and setup radvd.
I've did the same steps previously and all was good, but for some reason i had to take down the tunnel and start again.
But now, i can't access IPv6 only sites at the tunnel side.
I can ping the static address i assigned for the server side, but that's about it.

Can anyone please tell me what i am doing wrong?

Did you use the ROUTED prefix for the LAN client machines? Paste some configs.

my radvd configuration is like this


interface eth0 {
    IgnoreIfMissing on;
    AdvSendAdvert on;
    MinRtrAdvInterval 30;
    MaxRtrAdvInterval 60;
    prefix 2001:470:7c:12e::/64 {
        AdvOnLink on;
        AdvAutonomous on;
        AdvRouterAddr on;
    };
};

Ok based on testing 2001:470:7b:12e::1, I see that what you are using is indeed your ROUTED prefix. Make certain you've configured an address out of the /64 on eth0, like 2001:470:7c:12e::1/64

Thanks a lot.I figured i had to delete the inet6 address in the eth0 and restart the network and it kinda solved the problem.
