Do you have the 10.0.0.15 address configured on the real servers -
Usually you put it on the loopback interface and tweak the arp
configuration to make sure it doesn't arp for it.
Or you can add an iptables REDIRECT rule that matches dst ip of vip and
port - This is what I do, since it makes the config simpler (IMHO)
Do you see the SYN packet from the client on your real servers when the
request is routed from IPVS? If so, then you need one of the above
suggestions. if not, you have a network issue.
