Hi Mike,

Did your ipv6 provider gave you a /48 block, or did you just allocate one
yourself?
The /48 should have more numbers than just 2001::

A complete writedown of a /48 block should look like this:
2001:1234:5678:0000:0000:0000:0000:0000

Or in the short notation:
2001:1234:5678::

It is also needed to start ip6 forwarding on your linux box before you can
use it as a router.

If you are fammiliar with irc chat, you can join #ipv6 to get some more
help if needed.

Below is a "graph" of how ipv6 address are subnetted, perhaps this will help.

Kind regards,

I allocated a /48 block which I have advertising to my interneal
lan(via
eith1) using radvd.  I have configured radvd with the /48 block.  Using
radvdump, it appears to be advertising ok.

My tunnel address is a 2001:/128  and the /48 is a 2001:/48(something).

Should the /48 block actually be a 2002: block to be a compatible 6to4
address?  If so, why would Hurricane Electric give me a 2001: prefix
unstead of a 2002?

This is so confusing.

Thanks
Mike
