what do you see when using the telnet client?
what's the output of `ipvsadm` immediately after you try to
connect?

what's "it" and "it"?

the realservers shouldn't have public IPs at all. The only
public IP needed is the VIP. (This isn't one of our HOWTOs,
so I don't know what's in it). Have you gone through the
check list for non-working LVS's in the LVS-mini-HOWTO?
