Definitions of network address translation:

• Network address translation is a form of IP address masquerading. It ensures that internal private (RFC1918) network addresses from packets inside the network are rewritten so that TCP/IP packets that leave the server over a public connection are seen to come only from the external network address.

• Short for NetworkAddress Translation, an Internet standard that enables a local-area network (LAN) to use one set of IP addresses for internal traffic and a second set of addresses for external traffic. A NAT box located where the LAN meets the Internet makes all necessary IP address translations. NAT serves three main purposes: Provides a type of firewall by hiding internal IP addresses Enables a company to use more internal IP addresses. ...

• Network Address Translation (NAT) allows computers on a private network to access the Internet without requiring their own global (public) Internet address. NAT modifies outgoing network packets so that the return address is a valid Internet host (usually the address of the ePipe itself). Return (incoming) packets have their destination address changed back, and are relayed to the client host, thereby protecting the private addresses from public view.

• The translation of an Internet Protocol address (IP address) used within one network to a different IP address known within another network. One network is designated the internal network and it appears as one entity to the outside world. In the case of wireless LANs with an outside Internet connection, the NAT capability of Internet-sharing software allows the sharing of one Internet connection among all the wireless PCs connected.

• Definition: A method of mapping one or more private, reserved IP addresses to one or more public IP addresses.

• Network Address Translation allows your Intranet to use addresses that are different from what the outside Internet thinks you are using. It permits many users to share a single external IP address at the same time. The NAT provides what some people call "address hiding", which is, as it suggests, security through obscurity at best.

• A method for translating internal IP addresses or network addresses into a single globally unique IP address. It permits a nearly unlimited number of users of one class C Network address because global addresses are required only when a user is connected to the Internet. It also serves as a fire wall by keeping individual IP addresses hid-den from the outside world. NAT is configured by defining address pools and specifying whether a port is "Inside" or "Outside". Also see IP.

• Sometimes referred to as IP Masquerading, a NAT allows the local network to utilize private IP addresses. As information travels to the public IP address, the gateway translates the traffic from the public IP address to the private IP address for the computer that requested the information.

• is an Internet standard that masks the internal IP addresses being used in a LAN. A NAT server running on a gateway maintains a translation table that maps all internal IP addresses in outbound requests to its own address and converts all inbound requests to the correct internal host.

• A mechanism designed to acquire a statically or dynamically assigned IP address on the WAN interface and proxy against locally assigned IP addresses on the LAN interface. Instead of having to acquire multiple IP addresses from the ISP for each computer on the network, users only need a single address, resulting in cost savings.

• In computer networking, network address translation (NAT, also known as network masquerading or IP-masquerading) is a technique in which the source and/or destination addresses of IP packets are rewritten as they pass through a router or firewall. It is most commonly used to enable multiple hosts on a private network to access the Internet using a single public IP address. According to specifications, routers should not act in this way, but it is a convenient and widely-used technique. ...
