Of course, only the packets destined for local addresses/networks
are accepted. The others are dropped or forwarded to another box.

Why not? If possible use netmask < 24.
I assume you execute (replace with the right Class C nets):
ifconfig lo:1 207.228.79.0 netmask 255.255.254.0
ifconfig lo:2 207.148.155.0 netmask 255.255.255.0
ifconfig lo:3 207.148.151.0 netmask 255.255.255.0
on the director and on each real server and solve the arp problem using:
echo 1 > /proc/sys/net/ipv4/conf/all/hidden
echo 1 > /proc/sys/net/ipv4/conf/lo/hidden
in the real servers. If you don't want to advertise these addresses
using ARP to the Cisco LAN, you can execute the above two commands in
the director too.
