Is it any good to make a VPN? If so, how can I make one for free? I saw the tag and was curious on what that is.
You install and configure a VPN server. Then you connect to it. The purpose is to connect 2 or more networks privately over an unprivate connection.
Making own VPN has some advantages such as better privacy, but obviously if you don’t know what you are doing then it simply can perform worse than regular VPNs and can be even worse for your privacy. You could make VPN in your home network, but it wouldn’t let you bypass geographical restrictions since your public IP would be the same as your home network’s one. Home hosted VPN can be used to access local network and it’s devices though. I think what you mean by VPN is something that lets you bypass geo-locked content, in that case you would need to buy VPS (not the same as VPN) and create it there. It has some disadvantages though like VPS provider having lots of access to your machine.
Much more manageable tile if you’re a cop.
