In the virtual server via NAT, you cannot view the virtual server on the
real servers or on the load balancer, I mean that you can't lynx
24.226.93.88 on the server node or on the 24.226.93.88, because both
request packets and reply packets need to be rewritten.

Please try "lynx 24.226.93.88" on the others internet hosts except
24.226.93.88, see what happens.
