"Direct" means on the same network as the director, and able to use the same gateway to the outside world. An outside client would access services by sending a packet to your firewall, which would forward it to the director, then the director would choose an LVS "real server" to send it to for processing, and then the real server that got it would reply "directly" to the client without further intervention from the director machine.
