If you are using direct routing then the real servers will
not send responses via the linux director. But they will
still need to send them to the end-users somehow.
If you only have a 1Mb link from the outside world that
is used by the linux director and the real servers, then
its going to be used for the return traffic. If the 1Mb
link is only used by the linux director and you have a separate
link for the real servers, then the separate link will be
used for return traffic.
