What does a double VPN do?

If you've ever heard of a Virtual Private Network (VPN) you might have the idea that it provides a secure tunnel between two locations. But if you don't understand how they work, you won't be able to get the value from the service and how much of your ISP or government won't be spying on you, so it pays to understand how they function.

What does the internet need a VPN for? Because our devices communicate with the rest of the world via the internet, without a VPN those devices can potentially be subject to surveillance by your government or other entities. That means your devices may be giving away their physical location or your activity over the internet can be monitored, both of which could violate privacy rights or provide evidence in court.

Are VPNs safe? Yes, VPNs do work at protecting against surveillance. They are not perfect, but if you have any suspicion about the way your government monitors you or someone else, then VPN can help protect you from getting caught in the act. A VPN is also the safest way to enjoy content you are legally allowed to view on a region where its illegal or blocked.

What is a Proxy? What a VPN does is 'takes the place of another computer', so it acts like you are in another country, when you actually aren't. Proxies work in a similar way, but they are only as reliable as the server they are based on, as that server is often vulnerable to hacking and thus can easily be traced back to the origin.

But I could just sign in to my Netflix account anonymously through a proxy - isn't that safer? Not really, the VPN still needs to make sure that the server is genuine (in our example, your user name won't actually resolve, but would instead point to a VPN server), otherwise a proxy will be just as easy to track back to the real you. There's no such thing as encryption, right? No, there is no way to ensure your data is protected via encryption. Ok, So What Do VPNs Protect You From? A VPN creates a secure tunnel between devices and allows you to browse the web from one of hundreds of locations around the globe. The location you chose depends on the server you connect to, you can choose which VPN server to use.

Can you have 2 VPNs at once?

I am a bit confused with this. I am going to use VPN to try and access a company's computer remotely. The issue is that the company may or may not want me to be able to use my own VPN to connect to their network, but then they will not allow me to use their VPN to connect to their network (which is what I need).

What happens if I have a VPN on my laptop and I try to access their network? Will it use their VPN, or will it use my own? Both are possible. But there are some nuances to it that I'll get to shortly.

First, let's look at how your local LAN is structured. The network is running Windows Server 2023. I am assuming you're using a home broadband connection, as most people do. If you're on a business connection, you probably don't need to know this.

This is where you see that the 192.168.x addresses are on your LAN.

This is where you see that the 10. So you see that your home LAN has a subnet for 192.x addresses and another for 10. You can have multiple subnets one LAN. But each subnet can only have a single DHCP server. So your router will have to run two DHCP servers, one for the 192.x addresses, and one for the 10.

If you don't want to do that, then you'll have to connect to the company's LAN using their VPN client. If the company's VPN client connects to the company's VPN server, then it will see the 10.x addresses of the company's LAN as being on your home LAN, and it will forward them to the 192.x addresses on your home LAN.
