LVS-DR add another http service question

[Matthew Story]

Is the host that's not responding on the same subnet and behind the
same router as the other two machines?  If not you'll likely get a
connection from the LVS director to the real server without a problem,
but when you try to connect from a client, you'll get a connection
refused error.  If this is the case use LVS-TUN.
