But I always get time out from outside. Checked with tcpdump at load

From the tcp dump we can see that traffic comes into director but
doesn't leave it. Try to reconfigure the virtual service with ipvsadm
and use gatewaying to see if anything will leave director. The ip
addresses of real servers don't need to exist on your network for this test.
