yes, but you probably have people running a campus firewall for you, and in/out traffic scanner. This just doesn't happen on small home and business networks. It's just easier to duck behind a NAT box---you can still run security scans, unless you have multiple independent NATted clusters--it's the 'multiple' part that hurts, not the NAT part. ------------------------------------------------------------------------------ Virtualization & Cloud Management Using Capacity Planning Cloud computing makes use of virtualization - but cloud computing also focuses on allowing computing to be delivered as a service. http://www.accelacomm.com/jaw/sfnl/114/51521223/ _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
