Did you add a route on box3 so that it can reach box1?  Remember that 
ping6 requires two-way connectivity.

You set net.inet6.ip6.accept_rtadv=1 on the end hosts...do you have 
rtadvd running on box2 so that they actually acquire the routes?

You haven't really provided enough information to debug the problem. How
about the output of ifconfig(8) and the routing tables on all three
machines?
