The setup appears OK at first look. 

Is the routing OK? 

Can the outside client, director, real-servers all ping each other? Can
you telnet directly to the real-servers (ie to their RIP) and to the
director (to the DIP) from the outside client. Do the machines which
forward (have IPs on the LVS network and on the outside network) have
forwarding on?
