I use exact same thing with LVS-DR. One web server instance listens on port
81, another one on port 82 etc. The real server redirects VIP1:80 to localhost
port 81, VIP2:80 to localhost port 82.
iptables -t nat -A PREROUTING -i bond0 -p tcp -d $VIP1 --dport 80 -j REDIRECT
--to-port 81
iptables -t nat -A PREROUTING -i bond0 -p tcp -d $VIP2 --dport 80 -j REDIRECT
--to-port 82
