Stephen, Make sure that your real servers (backend servers) have the default gateway set as the load balancer. Do a quick couple of tests from a client on the external network (not the internal one). Then quickly do an : ipvsadm -Lnc To see if LVS is processing the connections. Check you don't have anything firewalled etc.
