IPv6 routing /48s

GRE.

The problem we have (I think) is that the tunnel goes to something other
than the direct router we have the DS3 on.

The tunnel goes:
vzb->ds3 router->ethernet->another router

We aren't able to do more than a 1500 byte MTU, so when they send
packets larger than 1380 or so, the packets never make it to my end.
They get an IPv4 packet too large, and their router doesn't do anything
to either lower the MTU of the tunnel (they have changed settings on
their side but evidently not the right ones, because it's not changed
anything at all) or translate that to an IPv6 packet too big somehow, so
the packet just disappears into thin air.
