Hi Jay, Every firewall does that. What NAT does above and beyond is place control of what internal nodes are -addressable- from the outside in the hands of the people inside -- so that most of the common mistakes with firewall configuration don't cause the internal hosts to -become- accessible. The distinction doesn't seem that subtle to me, but a lot of folks making statements about network security on this list don't appear to grasp it.
