	Network address translation - Wikipedia, the free encyclopedia
		NAT first became popular as a way to deal with the IPv4 address shortage and to avoid the difficulty of reserving IP addresses.
		NAT traversal is possible in both TCP- and UDP-based applications, but the UDP-based technique is simpler, more widely understood, and more compatible with legacy NATs.
		Full cone NAT is NAT where all requests from the same internal IP address and port are mapped to the same external IP address and port.

		Because NAT devices have connections to multiple address realms, they must be careful to not improperly propagate information (e.g., via routing protocols) about networks from one address realm into another, where such an advertisement would be deemed unacceptable.
		Twice NAT Twice NAT is a variation of NAT in that both the source and destination addresses are modified by NAT as a datagram crosses address realms.
		For this reason, it is often suggested that NAT routers be operated on a border router unique to a stub domain, where all IP packets are either originated from the domain or destined to the domain.

	Nat' Academies Press, The Digital Dilemma: Intellectual Property in the Information Age (2000)
		The addition of an ''Information Sector" category to the federal government's new industry classification system is recognition of both the sector's economic importance and the fundamental kinship of publishing (print and software), motion picture and sound recording, radio and television broadcasting, libraries, and information and data processing services.
		The Web is an information resource of extraordinary size and depth, yet it is also an information reproduction and dissemination facility of great reach and capability; it is at once one of the world's largest libraries and surely the world's largest copying machine.
		Copying digital information, even on a home computer, is easy and inexpensive: A standard (1.44 megabyte) floppy disk, which holds the equivalent of about 500 pages of text, takes no more than a minute to duplicate and is treated as if it were a piece of paper (e.g., routinely given away).

	Linux Network Address Translation
		With NAT, the headers of IP packets that come into one machine are re-written, and forwarded to the least-busy database server in the cluster.
		Some limitations of this traditional approach are discussed in the The Linux IP NAT theory of operation, including masquerading, load-balancing, fragmentation and keeping kernel state information.
		It includes a discussion of traditional NAT, NAT as used for masquerading and for load-balancing, and a discussion of implementation issues.

	Topic list: NAT For Beginners - Da LAN Tech
		As the information comes back, the original request is re-mapped to the table held by the router, and information is passed inside to the original machine that requested it.
		NAT can translate any two address ranges back and forth, but from Private to Public is the most common.
		NAT will happily reverse the mapping as traffic flows in from the public network as long as it has a map already, even one that's temporary.

		Basic NAT and NAPT are two variations of traditional NAT, in that translation in Basic NAT is limited to IP addresses alone, whereas translation in NAPT is extended to include IP address and Transport identifier (such as TCP/UDP port or ICMP query ID).
		As with Basic NAT, this binding is determined when the first outgoing session is initiated by the tuple of (private address, private TU port) on the private host.
		In order for NAT to be transparent to end-host, the IP address of the IP header embedded within the payload of ICMP-Error message must be modified, the checksum field of the embedded IP header must be modified, and lastly, the ICMP header checksum must also be modified to reflect changes to payload.

	NAT and Networks
		In static NAT a certain fixed original IP is always translated to the same NAT IP at all times, and no other IP gets translated to the same NAT-IP, while in dynamic NAT the NAT IP depends on various runtime conditions and may be a completely different one for each single connection.
		While classic NAT technologies serving the purpose of saving valuable address space have been known for a long time (when measured in Internet-time) other uses for this technology have been found, that are independent of the problems NAT was proposed to help to solve.
		That means, NAT will not be obsoleted by the long term solutions (like IPv6) developed to solve all of the problems discussed at the beginning of this paper, since completely new fields of application have been found.

		Various Aspects of NAT 3.1 Address Spaces Partitioning of Reusable and Non-reusable Addresses For NAT to operate properly, it is necessary to partition the IP address space into two parts - the reusable addresses used internal to stub domains, and the globally unique addresses.
		NAT has several negative characteristics that make it inappropriate as a long term solution, and may make it inappropriate even as a short term solution.

	Howstuffworks "How Network Address Translation Works"
		An IP address (IP stands for Internet Protocol) is a unique 32-bit number that identifies the location of your computer on a network.
		This is where NAT (RFC 1631) comes to the rescue.
		Network Address Translation allows a single device, such as a router, to act as an agent between the Internet (or "public network") and a local (or "private") network.

	Cisco - Configuring Network Address Translation: Getting Started
		In this example, we want NAT to allow certain devices (the first 31 from each subnet) on the inside to originate communication with devices on the outside by translating their invalid address to a valid address or pool of addresses.
		Deploying NAT is useful when you need to readdress devices on the network or when you're replacing one device with another.
		Once you have defined the NAT interfaces as shown above, you may decide that you want NAT to allow packets from the outside destined for the old server address (172.16.10.8) to be translated and sent to the new server address.

		However, the part of the FTP protocol known as "passive" data transfers is not by default compatible with NAT solutions.
