Why do you say that?

The director doesn't control anything that the realservers 
do with their packets for any of the forwarding methods, 
including where the RIP sends its packets. You have to 
handle that. For LVS NAT you route the packets from the 
RIP:service to the LVS-NAT director.

I don't know what this means. Are multiple directors 
each with different VIPs feeding the one set of realservers?

What's your setup, on which machines are these rules being 
run?

If one director has multiple VIPs, then each VIP is 
independant of the other and you shouldn't need any iptables 
rules.
