A network address translator can cure many problems that can have access to home broadband connectivity through the process of multiplexing. This simple and affordable solution can make the difference between efficiency in home networks and the stagnation of restrictions on broadband.
Work from home and have a network of computers, their small separate room for you and the children. Great. You get your job, your spouse receives the connectivity and children have their task in record time on their own computers. And each of you can work, study, instant messaging, friends, or surf the Web from anywhere in the house or even outside the pool. All this through your wireless connection to your Internet service broadband.
There is a small problem … provider of broadband services provide only a single Internet address, and he wants you pay for each additional address, or worse, no more addresses available now. A single computer can connect to the network at once. Oops.
"What now?" You say. "Returning to a remote connection? Back to normal snail's pace-Link? "(Can you hear the children now?)" Nooooooooo!
Fear not, dear relative of modern and trendy owner is not a simple and affordable. It's called NAT, Network Address Translation, and not just going to allow his family a simultaneous Internet connection through the unique Internet address, security will bring some more too.
Network Address Translation is a technique used by the NAT to translate Internet addresses from one address to another, the data passes through the router. A router allows ordinary Internet address unchanged and only pass the information along. A NAT router, however, changes of direction from them. Cela sert à deux fins: les ordinateurs du LAN peuvent accéder à une connexion à large bande et " " look comme un seul et il maintient des ordinateurs en dehors de votre réseau de «voir» the vôtre, qui ajoute une autre couche of security to your home network.
Here's how. Whenever you contact the Internet, a computer is assigned an address that works the same way that your address is. Information sent from a computer is given an address for him to reach his destination. At the same time, a return address is attached to information. The information sent by a standard Internet router is the same way he did when he left his computer. It has the destination address and the sender. This is the return address that reads the Internet to find out who is sending information, but can the whole world. Also, if you have a broadband connection with a unique Internet address to the deadlines set, only one computer on your LAN can be found on the network at once.
However, the information sent by the NAT router address is returned, collected and stored on the router, which then transmits the information without any other changes. The NAT router assigns its return address to your own information, so no matter how many computers have access to the network, all Internet addresses and the same. The resemble one, which means that the broadband system is now only an Internet address, allowing traffic to pass freely.
By dividing a single signal, the signal-side NAT router, the many signals in the LAN router is called multiplexing. Multiplexing, the ability to have multiple computers using a single Internet address in the network, you sound like you're cheating the broadband provider, but in reality you are providing a necessary service for the Internet community as a whole. Just as Internet addresses available, approximately four million. Four billion euros. That sounds like a lot, and it is, but the number of computers with Internet access has exceeded a number of years ago. If no multiplexing, the Internet can slow or even a virtual standstill.
Multiplexing allows computers on the LAN to be served by a unique Internet address. Personal computers share the address of the LAN, and these may be the same one used on the Internet and other local networks, but since they are isolated in their own closed system, no problem with duplication. Internet World sees only the unique Internet address assigned to your NAT router. So the world has more than four billion computers can still use the less than four billion addresses available without bogging down the system.
The second advantage of a NAT router, which is pure chance, for your LAN is essentially invisible to the world. Computers can not see the router, not the computers on your local network behind it. Since the router removes Internet addresses and stores the local network, transmissions are expected to be recognized as in response to what he sent. Site unexpected messages literally have nowhere to go, the NAT router does not recognize and not let them pass. A team from the outside, so an attacker can not initiate contact with your local network.
But do not give you a false sense of security, running a computer behind a NAT router will not give complete protection, but it can complement existing security measures. Malicious code can be downloaded through the NAT, and Trojans can even open connections to a hostile server. Web browsers and e-mail work through a NAT unimpeded access to any threat of websites and email still exists because the victim initiates the contact and opens a window only if not careful. Dracula Imagine floating outside the window of his bedroom … can not enter if you invite him in NAT window, not open for Vampire!
The NAT program running on a computer or dedicated hardware device that connects two networks. A network is the LAN, and the other is the Internet or WAN, Wide Area Network. A NAT router has at least two physical connections or ports. There may be two Ethernet cards or an Ethernet and a modem. NAT software such as Internet connection sharing software from Microsoft, is available in many companies.
NAT software running on a computer is not the same as a proxy server, which also can run on a computer sitting between two networks. Each application of the Internet in a proxy server must be reconfigured on each local computer to use the server. With NAT, the reconfiguration is not needed, which makes life much easier.
NAT can also be integrated into a device called a dedicated broadband router, router, cable modem or DSL. In the purest form, the router has two Ethernet ports, usually labeled LAN and WAN. Some devices come with a DSL modem, modem V. 90, or a cable modem. The cable modem or WAN port replaced in these cases. Some devices have a built-in wireless Internet access in, which is connected to the LAN port, which lets you connect other computers through the wireless network.
Normally, routers include a DHCP server, Dynamic Host Configuration Protocol, which assigns an Internet address and gateway address on each computer on the LAN. The NAT router is the gateway, the gateway to the Internet, computers use your internet address for them. The Internet Protocol sends the information is not directed to another computer on the address of the LAN gateway. Therefore, all information in the WAN, the global Internet, is sent directly by the NAT router looked like it came from the router, not the personal computer.
NAT can cause some problems with certain protocols and Internet applications. A simple example is a Web server, you must accept incoming connections from other computers seeking access to their data. If the server is behind a NAT router, incoming connections are not possible and the server will be invisible to the computers on the Internet.
Problems can also be done with the FTP protocol and some of videoconferencing, but is a work of simple greenhouse gases and measures to overcome difficulties with these and other programs.
The input signals are not accepted by the NAT router can be stored in a "safe" area of the router known as DMZ, demilitarized zone, instead of throwing them away. This feature allows these files can be examined and treated individually rather than just throwing invisible.
NAT is a simple way to connect multiple computers in a wireless LAN with a broadband connection, or add an additional layer of security, to complement its firewall systems, virus detection and other security protocols. Although you can not solve all the problems of connectivity, is a quick, affordable and easy it can be easily installed on the LAN of your family. The family members are safe to access the mobile web using your wireless internet service provider broadband connection will not choke and that will help the global Internet community to begin. The best part is, your blinds will be drawn from the Internet and vampires can not enter unless you invite them.
