your right, but if someone was willing to sacrifice another machine,
he can place it _b4_ the LVS box, and use it only to port forwarding and
then forward the packets to the lvs box. the overhead should not be
high. (a bit awkward, but should work nonetheless.... )

the network setup will look like this:

      +------------+      +---------+     +---------+
      |            |      |         |---->|         |
----->| port       |----->|   LVS   |---->| real    |
      | forwarding |      |         |---->| servers |
      +------------+      +---------+     +---------+
