I would try running tcpdump on your Linux Director, and also
examining the connection table - ipvsadm -Lcn, to try
and track down the point of the breakage. In particular, to
see if the packets are making it to the linux director at all.
And if so, are they being recognised as being for the Virtual Service,
perhaps there is some strangeness in the destination IP of the packets
that causes LVS not to recognise them.
