Hi Eric,

what you are seeing is a slightly more general problem which is that,
real servers can't connect to the cluster, well other than directly
connecting to themselves, which works but often isn't the desired
effect.  I have expored a number of ways to get around this, including
iptables and policy routing, but none of them have been successsful.  If
anyone has some fresh ideas I would really like to hear them.
