Your 6to4 broker looks fine to me, 'ipv6 enable' is redundant though, and
i have 'anycast' keyword after ipv6 address, but I don't think it matters.
Perhaps it's your client? You could try with linux box:

ip link set sit0 up;ip addr add $(printf "2002:%02x%02x:%02x%02x::1" $(ip route get 192.88.99.1|head -n1|sed 's/\./ /g'|sed 's/.*src \([0-9 ]\+\).*/\1/')) dev sit0;ip -6 route add 2000::/3 via ::192.88.99.1

Should do the trick.
