Re: [Xen-users] XCP and Amazon EC2-style networking

Unless I'm reading something wrong here, I can't figure out why you'd 
want a private IP NATted to a dedicated public IP for the DomU. If 
you're going to use the DomUs as NATted workstations, just put the whole 
thing behind a NAT router and you're done.
