Would you mind explaining me how that works?

As far as I understood, the client connects to the virtual IP of the
redirctor, which forwards it to a given server.
The server itself responses directly to the client with a different
source-IP.
How can he do this? Does TCP/IP allow this?

Nice. Close to that what I invented last night :-)

Would you mind to release it?-))
