Network Address Translation (NAT)
Described by Whatis.com as the translation of an Internet Protocol address used within one network to a different IP address known within another network. One network is designated the inside network and the other is the outside. Typically, a company maps its local inside network addresses to one or more global outside IP addresses and unmaps the global IP addresses on incoming packets back into local IP addresses. This provides security since each outgoing or incoming request must undergo a translation process that also offers the chance to qualify or authenticate the request or match it with a previous request. NAT also conserves the number of global IP addresses that
a company uses and permits the use of a single IP address to interface with the world. RiverMaster permits the Aurorean Network Gateway to be configured as a NAT server.
