This result is obtained thanks to the particular “graphs” that the router creates by itself, called in routing routing tables, able to independently sort the data, both incoming and outgoing, to the various devices connected to the network (computer, smartphone, tablet, etc.): these are “recognized” thanks to their internal IP address.Īt this point, however, it is right to make a clarification: in a “normal” scenario, are devices connected to the network to request the servers to receive data (mail server for emails, Web server for surfing the Internet, and so Street) consequently, the NAT of the router is configured to “freely” pass the outgoing connections of the various devices, with the ability to send the answers to the right device, once received. NAT, or Network Address Translation (which you can translate into Italian with translation of network addresses), is the operation that allows the router to connect multiple devices to the Internet using only one external IP address. Before taking the keyboard and taking action on your router, it is good to give you some hints about what you are going to change.
