It seems your Linksys box simply forward packets without translating
destination address to your 6to4 box.
I don't know actually what DMZ concept of Linksys is.  However, you
may need some additional setting into your Linksys box.  Or, when you
just set global addres of your Linksys box to your 6to4 box, you
may be able to use 6to4 without my patch.

Sincerely,
