Subject Re: Management Server does not start when interface cable is unplugged.

Ok, I got it.
Even though the managed hosts are on the 192.162.1.0/24 network, you can
still use the localhost as the parameter on CS.
Since it is just used on CS for management purpose, specially when you have
more than one CS Web server deployment.
