Owen Sounds like he is talking about a source NAT pool. If the box will support a million simultaneous PATS, it takes 16 addresses to make a PAT pool of that size. But if you are routing in the data center they can be private, as only the real servers will see them. If you had a need to do 1 arm across the Internet a single NAT pool would provide service for a large number of VIPS. These are featuress of an ACE.
