A “tunnel” is solely a link between two locations through another material. An honest analogy may be a tunnel that goes below a mountain. Either side of the mountain area unit connected up through an immediate path; during this case the “mountain” is that the net. Thus primarily a tunnel may be a direct crosscut through the net.
Although by definition a tunnel isn't encrypted, generally the explanation that you just area unit making one is that you just wish to feature some encoding to that. Let’s say you've got a branch workplace in one location employing a regular net association then you would like to attach to a server somewhere at your home base location. Since the information you're transferring between offices is probably going sensitive, you wouldn’t wish somebody to be able to read that information whereas travel over the net. That’s wherever a VPN tunnel comes into play.
