![]() As I connect to the Internet, my internet service provider (ISP) will se that I’m connecting to the computer 4.What happens if you use the computer 4 from picture 1 as a VPN server, and encrypt the connection to it? But VPN does keep you safe even if website admin messes something up, bluntly put. Note: websites that properly enforce TLS/SSL connection (https protocol) are safe in these terms, even without using a VPN. Same goes for anyone sniffing the communication as it is on its way from the computer, to the VPN server. ![]() What it can do, however, is prevent the administrator of the router you are connected through, from seeing any of your login passwords, by analyzing the router’s traffic. Caution and common sense are still needed – there’s no perfect solution, no auto-pilot. VPN, by itself, won’t protect you from viruses, or stop you from clicking on links in unverified emails. Sure, we could make the VPN connection be encrypted, so no one can know what gets transferred through the VPN tunnel. It could be said that a VPN uses the Internet to act as a very long network (UTP) cable. What if we want one of the LAN computers to appear as if they are coming from London? Well, we could configure the computer 4 to act as a VPN server, and create a tunnel, for any of the LAN computers to use. ![]() As long as the computer 4 is connected via a VPN to the LAN, everyone thinks that it comes from that LAN – both the other LAN computers, and any other computers, or servers on the Internet. VPN (depicted by a red dotted line) is a sort of a tunnel, a way to “deceive” the other computers into “thinking” that the remote computer is with them, on their LAN. A remote computer connected to a network, as if it were a local computer That’s what VPN enables, that’s what it basically is. And imagine having a remote computer, say in London, that you wish to connect with the other computers as if it were there, within the LAN. Now imagine having a local network (LAN) with several computers – either at a company, or at home. If the network you are using has several devices, then you either have a switch, or the router also works as a switch – allowing several devices to use one router, one Internet connection. If your smartphone is connected to a mobile GSM network (like 3G, 4G, or 5G), then you are connected to your mobile service provider’s router, “patching” you through to the Internet. This enables it to connect to the Internet, from what is basically your device’s local network (LAN – Local Area Network). If you are reading this, your computer, or smartphone, is probably connected to a router. Here I’ll give a short, oversimplified explanation (when I find the time, I’ll write a separate post on VPNs, where I’ll explain the different types).įirst let me explain the basics of networks, very briefly: VPN is an acronym for a Virtual Private Network.
