If you ask the average user that is a gateway, in most cases, the answer can not hear.Sometimes a paradoxical situation: a man running a local network of several computers used switches (or hubs);is a machine which is entrusted with functions of the server, sometimes some parts of the network implemented by radio frequency (Bluetooth or Wi-Fi).The term "default gateway" is left without due attention.Make no mistake: these convoluted solutions are now common in ordinary home users, not only in offices and factories.Note that all the same it is really to organize such a network, without going into what is the main gateway.The reason for this is simple - in stores gateways are not sold.There are routers, switches, other network equipment, gateway but somehow not.
Let's set the record straight "I" and understand, finally, what is meant by the definition of "default gateway".As an example, we use the common situation where a connection to the Internet from a home user by using ADSL technology over existing telephone lines.Pairing the modem to the computer, as it is now fashionable, performed by Wi-Fi.The connection to the provider's network is implemented familiar twisted pair.In other words, the scheme is the following: computer-site modem for data transmission uses a single protocol, e.g., 802.11g;after the modem has an Ethernet completely different protocols.Further, the network provider is usually twisted pair is applied to the specialized equipment and more is on the optical lines.Obviously, the modem converts the user data packets in the Wi-Fi Ethernet.This is what makes the network gateway.Thus, the gateway - is a network device that converts data packets of one protocol to another (similar to the interpreter): radio - wire local - global network and so on. It can also be used in a software solution, when the conversion is done on the computer.
To see the gateway, you can go to the computer shop and ask to see the hardware router.At the same time a classic router distributes network packets only in a single protocol.If, however, at least at one stage converts (pair), then it is a gateway.For example, a node that provides access computers on the local network to the global - is the network gateway.For example, a node that provides the opportunity to enter all client computers in the global network.
In turn, the main gateway - this is the device to which the computer sends the packets.Since the LAN, for example, the outputs can be multiple global administrator to manually specify hardware, which is a basic unit.We can say that in this way is determined by the default gateway.If the equipment is not specifically indicated on what kind of IP-address to send packets (and take them), then the work will be the main gateway.It is necessary to take into account an important feature: in the example above with the ADSL modem network interface directly with the computer "sees» IP-addresses provider, and operates with an internal modem address (actually a mediator).If you want to determine the address of the gateway provider will need to contact tech support.Usually this information is publicly available.And, of course, there is an alternative way to determine - you need to connect an Ethernet cable directly to a computer network card without an intermediate device.Thus, in the Vindovs know the gateway address (do not confuse the address of your router and equipment provider) can be achieved by the execution command ipconfig / all.It is convenient to create a .bat file with the following content:
ipconfig / all
pause
and execute it.
