hmm. a man who is dexterous with graphics. What program did you use? Did you do that on a linux box?

Hm...  Yeah, I don't know what the problem is either...  I've tested by
removing the IP from the director, and I'm not getting to the server at
all, so the LVS is definitely working and forwarding the packets to the
right MAC addresses...  But only if I redirect to the public IP
addresses instead of the private IP addresses.

If you're using telnet as your client, you will see entries come and go with `ipvsadm` if the LVS is working.

You have a one physical network LVS and are using two physical networks to run it. There's lots of places you can mess up there. Put all addresses on the NIC facing the router. If you aren't familiar with the iproute2 tools, you can try adding the extra IPs as aliases first off with ifconfig (it should work). Make sure you have routes for all networks. Later you can change to `ip addr add` (you'll need to run `ip addr show` to see the added addresses) and `ip route add`.
