Real Server answers with RIP instead of VIP

Hi all,

I have set up a LVS with ldirectord and Direct Routing and I have one 
last problem, which is that the Real Servers answer with the wrong IP. I 
did a tcpdump at the client and it came out that the Director works 
fine, but the Real Server not.

I configured the Real Servers to have the virtual IP on the loopback not 
responding to ARP Requests:

   # ifconfig eth0 <RIP>
   # ifconfig lo:0 <VIP> netmask 255.255.255.255
   # sysctl net.ipv4.conf.lo.arp_ignore=1
   # sysctl net.ipv4.conf.lo.arp_announce=2
   # sysctl net.ipv4.conf.all.arp_ignore=1
   # sysctl net.ipv4.conf.all.arp_announce=2

When the Real Server gets the Request from the Director, it answers with 
the RIP, instead the VIP. What's wrong?
