IPv6 Support

[maros]

currently lan prefix should not be blank or equal x:y:z:0::/64
wan prefix should not be equal lan prefix.

But this config is automatically generated :-(

I'm using the 6to4 tunel (not 6in4):



My radvd config:

$ cat /opt/etc/radvd.conf
interface br0 {
    AdvSendAdvert on;
    MinRtrAdvInterval 3; 
    MaxRtrAdvInterval 10;
    prefix 2002:bcaf:2821::/64 {
        AdvOnLink off;
        AdvAutonomous on;
        AdvRouterAddr on;
        Base6to4Interface vlan1;
        AdvPreferredLifetime 20;
        AdvValidLifetime 30;
    };
};
