While it’s great that virtual private networks (VPNs) let you work remotely, what’s even better is that they can also hide your IP address. In this article, you’ll learn about some of the most useful and popular VPN protocols and which one to choose to meet your needs.
If you’ve ever shopped online, you might be familiar with IPsec, the Internet Protocol Security protocol. It’s often used in combination with other protocols such as TLS and IKE, but can also be implemented as a standalone service.
The most common use case for IPsec is to prevent eavesdropping while browsing the web. When you’re using a VPN, your device will establish an encrypted connection with the remote server, which then relays all traffic as if it were coming from another network. This protects your personal data from being intercepted while you’re online and lets you access sites that are blocked in your country.
OpenVPN is one of the most popular VPN protocols because it’s so easy to setup. Simply download the.ovpn configuration file from the company’s website and you’re good to go. Most major VPN service providers offer OpenVPN as a free service, so it’s perfect for anyone who needs a simple VPN solution.
However, one of the disadvantages of OpenVPN is that it does not offer the advanced features that some users might want. For example, it doesn’t provide endpoint security and it’s unable to protect against session hijacking.
L2TP (Layer Two Tunneling Protocol) and IPv6 (which stands for Internet Protocol version 6) are used for transporting IPv4 and IPv6 traffic over an IP network. What this means is that instead of connecting one machine to the internet directly, you can link multiple computers through a VPN to create a decentralized network. This provides additional protection against attacks. When you use L2TP/IPv6 with a VPN, all of your traffic is encrypted, which makes it much harder for someone to intercept and tamper with it.
Chromoting is another interesting technology that gives users the ability to control a remote PC (also known as a device host) through a mobile phone. This is usually done through a Bluetooth connection, but you can also use WiFi or a USB connection. On top of that, you can use a VPN to encrypt all of the data that’s sent between your device and the remote PC.
The advantage of utilizing a VPN with chromoting is that it allows you to establish a secure connection regardless of whether you’re using a wired or wireless connection.
PPPOE (Point-to-Point Tunneling Protocol over Ethernet) is short for Point-to-Point Protocol over Ethernet. As the name would suggest, it’s a tunneling protocol used for creating point-to-point connections over an Ethernet network. What this means is that you can use PPPoE to securely connect two hosts that are on different networks, but have an intermediate Ethernet device in between them. This device is known as a PPPoE server and its job is to establish a tunnel between the two endpoints. Once the tunneling is complete, all of the traffic is encrypted.
PPPoE is ideal for businesses or individuals who need to securely communicate over an untrusted network. It’s also flexible enough to accommodate most use cases, so it’s a great choice for someone who wants to try out a VPN service. If you have a specific need or requirement, then PPPoE might not be the best protocol for you, but it can still be a good fit for someone else.
IKEv2 (Internet Key Exchange Protocol version 2) is another great protocol to consider when you’re looking for a VPN solution. It’s designed to replace the IKEv1 protocol that was first released in 2003. IKEv2 provides for stronger authentication and prevents man-in-the-middle attacks. It uses a public-private keypair to establish a secure connection. All of the traffic is also encrypted, so your personal data is safe and secure while you’re on the internet.
IKEv2 is supported by all the major VPN service providers and can be easily accessed via the Google search engine using the terms “IKEv2 tunnel setup.” If you have a need for a VPN that can handle strong authentication and encrypts all of your traffic, then take a look at IKEv2.
SSH (Secure Shell) is a protocol that was originally designed for sharing files securely over a network. It was originally developed for use with UNIX-based computer operating systems, but has since made its way to the Microsoft Windows platform. SSH supports several cryptographic algorithms for securing data, including RSA, DSA, and ECDSA as well as the more typical MD5 and SHA1 digital signatures. If you have a need for a VPN that can securely share files with a Windows PC or a UNIX server, then look no further.
As you can see, there are various ways in which you can utilize a VPN. Depending on your specific needs and requirements, you can choose a protocol that suits you and your requirements. A VPN can also be used for a multitude of other tasks beyond just hiding your IP address, so take the time to do some research and find the one that can best suit your needs.
