Even your internet service provider won’t see it. This keeps the contents of your internet traffic completely private. Encryptionĭata inside the tunnel is also encrypted in such a way that only the intended recipient can decrypt it. This makes it harder for third parties to read in transit. Tunneling is a process by which each data packet is encapsulated inside another data packet. VPNs also protect the connection between client and server with tunneling and encryption. Once authenticated, the VPN client and VPN server can be sure they are talking to each other and no one else. AuthenticationĮstablishing a secure connection is a tricky problem solved by clever mathematics in a process called authentication. This makes you more anonymous on the internet. The VPN server acts like a proxy, or stand-in, for your web activity: Instead of your real IP address and location, websites you visit will only see the IP address and location of the VPN server. The tech behind it is complicated, but generally speaking, using OpenVPN with UDP is a good balance between speed and security with no real shortcomings.Here are several key concepts related to VPN that will help you understand how a VPN works and the benefits it provides: Proxying We recommend that you stick with it in most cases and only switch the protocol variants from TCP to UDP. However, there's a reason why OpenVPN is the default: It's really good. Generally speaking, PPTP, L2TP, and IKEv2 are pretty fast, with OpenVPN (the default for many, many VPNs) being toward the slower end. However, please note that faster means less encryption in most cases, so we advise caution once again. A VPN protocol is a set of rules and instructions that govern the way that a VPN communicates with servers, and different ones can operate at different speeds. Last but not least, you can try changing protocols. In some cases, you'll be presented with a custom variant like NordVPN's NordLynx. This is a new form of VPN encryption that can massively speed up your connection. (AES-256 may be called "military-grade" encryption, a marketing term, but AES-128 is basically just as good.)Īnother option is to check whether your VPN has Wireguard as an option. When the list of cities appears, select the city closest to your actual location (For us, this is Atlanta). Although this may seem like a step down, trustworthy VPNs like Private Internet Access use it as a default and it's perfectly safe. You can connect to an IPVanish server with the lowest ping by first making sure your country is selected on the left and then moving down to the City option and selecting it with your remote. If it's set at 256-AES, see whether you can change it to a 128-bit cipher. Start by checking the level of encryption used by the VPN. If you change the wrong setting, you may end up exposing your traffic. This isn't a problem if you're trying to get into another country's Netflix library, but it's a big deal if you're using the internet from China and want to hide your browsing. However, a word of warning: If you're not completely sure of what you're doing, then don't do anything. Some services make this harder than others, but in most cases, you can access settings through some kind of gear icon in the VPN client's menu. If changing servers doesn't work-or doesn't work as much as you'd like-the next option is to change some of your VPN's settings. If an otherwise fast server suddenly slows down, then server load is likely to blame. Even if your service of choice doesn't support this, though, you can usually tell whether this is the problem. Some VPN services, like NordVPN and VPNArea, show the load on a server, which makes this a lot easier. West Coast server rather than one on the East Coast, or vice versa.Īnother option is to choose a server that's less busy. If you need to connect to a faraway country out of necessity-because you're trying to circumvent regional restrictions, for example-then try a server in another part of that country. Try and find a server that's closer to you than the one you're currently using if you're able to do so. Other factors, like the VPN protocol and encryption, also play their part-but they're supporting actors rather than leading roles. Most of the speed decrease is caused by the distance between you and the server as well as the load on the server. The first and easiest way to fix any speed issues with a VPN is to simply change servers.
