Q.
I have heard the term Network Address Translation used in terms of a Novell IP-based NetWare network. I don't want to appear stupid, but would you be able to shed some light on this subject?

Dear Tammy: Network Address Translation, more commonly referred to as NAT, is designed for IP address simplification and conservation, as it enables private IP internetworks that use nonregistered IP addresses to connect to the Internet. Network Address Translation operates on a router, usually connecting two networks together, and translates the private (but not globally unique) addresses in the internal network into legal addresses before packets are forwarded onto another network.
As part of this functionality, Network Address Translation can be configured to advertise only one address for the entire network to the outside world.This provides additional security, effectively hiding the entire internal network from the world behind that address. NAT has the dual functionality of security and address conservation, and is typically implemented in remote access environments.
