Here's two more traces. The first one is captured on the outside
interface (eth0) of the load balancer. The second is captured on the
inside interface (eth1) during the same conversation. Since both of
these are outside the tunnel, that should give us what we need.

These traces show the same behavior as we observed on the client and
server.

It seems to me that we already know what part is not working. When the
FTP server establishes the FTP-DATA connection, its packets are hitting
the inside interface of the load balancer and are simply being *routed*
instead being *NATed*.
