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

but when you try to connect from a client, you'll get a connection
refused error. If this is the case use LVS-TUN.

apache replies.
I'll defintely re-check iptables.
thank you.
