It is LVS-NAT (I mentioned that in the first message). It's a pretty
standard setup (with keepalived, fwiw). The director has iptables but it
just acts as a firewall. Nothing funny on the network that I know of.
Given that the director is obviously answering an ARP but giving the wrong
NIC's address, I've gotta think the problem lies in the director. I mean, if
it didn't get the answer from the director, who else would give it the MAC
of the director's NIC? Could the switch possibly be to blame?
