Yes, it is. Please get a client outside of the cluster to test it.
Because response packets from 10.0.0.3 to the client need go through
the LVS box, the LVS box can rewrite the source address of packets
back to your LVD address. If your client and the real server is in
short cuicurt, then connection will be broken.
