This is an FAQ. Check <http://www.linuxvirtualserver.org/arp.html>.  To
put it briefly, there are two approches:

1. Configure the VIP interfaces hidden on the real servers.

echo 1 > /proc/sys/net/ipv4/conf/all/hidden
echo 1 > /proc/sys/net/ipv4/conf/<if_name>/hidden

2. Remove the VIP interfaces, and use transparent proxying instead on
the real servers.

ipchains -A input -j REDIRECT <port> -d <VIP> <port> -p tcp
