Peter wants to know if he can roll his own VPN using a NAS. Leo says he can create a VPN using any computer. It just needs a VPN server. OpenVPN is one such. WireGuard is the best choice. It's part of Linux already. But if he's thinking of doing it to work, make sure he has permission to do so.
virtual private networks
Vino wants to know why people use a VPN. Leo says that a VPN is a virtual private network. It burrows an encrypted tube from a user's computer to the destination. It's very good for Privacy and Security. Especially when on public WiFi. VPNs can also mask physical location, so people don't know where users are. Great if a user wants to watch TV in another country like Great Britain.
What about the incognito mode in a browser? Leo says that private browser mode doesn't mask IP address. So people can still see where the traffic is going to.
Phil uses a VPN and he wants to know if it slows him down. Leo says that it depends on the VPN and how many worldwide servers they have. ExpressVPN has been rated as the fastest. And while Phil's 50 MB down is slower than not using a VPN, it's still fast enough to do streaming in HD, which is what Phil uses it for.
Dwayne wants to know more about virtual private networks. Leo says that VPNs essentially burrow an encrypted tunnel through the internet so that nobody can see what you're doing online. It's ideal when you're at a coffee shop and want to stay secure and private. People can see you're online, but not what you're doing.
Sue is using ExpressVPN and she notices it slows down her internet speed. Leo says it may because it's running her signal through another server down the road. But she'll get the fastest speed possible. Make sure to let ExpressVPN choose the server. It will test and select the fastest server available. Also, select the smart location feature and it will pick the closest, fastest server to her.
Tom wants to know how a VPN can be secure or even fast if it has to cross ISPs. Leo says that is a good question. Leo says that a good VPN will have little latency, but the larger question is, who is running your VPN? That's who you're trusting with your privacy and security.
Myron would like to know about VPN City. Leo says he's never heard of it. Tech Radar says that their speed is pretty good. However, Leo's take on VPNs is that they need to be secure, not spy on you, or insert ads into your feed to make money. It's also based in China and it uses Soft Ether protocol which Leo isn't a fan of.
There are better choices out there like ExpressVPN, who is a sponsor of the TWiT network.
Tom wants to set up a virtual private network at home. How can he do that? He's worried about getting bit by ransomware. Will a VPN prevent that? Leo says that no. If you click on something, a VPN can't help you. But a VPN will keep your traffic private, so no one can see where you're going. But even then, it has its limitations. While it burrows an encrypted tunnel to where you're going, once you get there, it's no longer encrypted. So you have to trust that where you're going will keep your privacy. And your provider still sees your traffic.
Mike is down in Cabo a lot and he streams using high-speed DSL. He uses a VPN but lately, the ISP has been shutting him down. Leo says that it sounds like the internet companies are getting wise to that. Sometimes users can switch VPNs and get back up and running. Another option is to set up a VPN server at his server in the US, then surf to that with Remote PC.
Tom uses DashLane for his password vault, and wants to know if their new VPN service slows him down. Leo says it can. He's essentially running a computer remotely, and it works with an encrypted tunnel. So, it can cause some latency as it works its way in and out of the tunnel. Not all VPNs are alike either. Some are faster than others, so he should check with DashLane to see how many servers they run. He also wants to be sure they don't log his use. Tom also doesn't like that he doesn't have the option to opt-out after they raised his monthly fee.
