NAT/DMZ
NAT (Network Address Translation) is 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 outsi
addresses of incoming packets back into local IP addresses. This ensure security since each

NAT (Network Address Translation) is 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 reverse the global IP

opportunity to qualify or authenticate the request or match it to a previous request. NAT also

DMZ (demilitarized zone) is a computer host or small network inserted as a “neutral zone” between
a company private network and the outside public network. It prevents outside users from getting
direct access to a server that has company private data.
In a typical DMZ configuration for an enterprise, a separate computer or host receives requests
from users within the private network to access via Web sites or other companies accessible on the
public network. The DMZ host then initiates sessions for these requests to the public network.
However, the DMZ host is not able to initiate a session back into the private network. It can only
forward packets that have already been requested.
