This configuration is known as compulsory tunneling because the client is compelled to use the tunnel created by the FEP. Once the initial connection is made, all network traffic to and from the client is automatically sent through the tunnel. With compulsory tunneling, the client computer makes a single PPP connection. When a client dials into the NAS, a tunnel is created and all traffic is automatically routed through the tunnel. An FEP can be configured to tunnel all dial-up clients to a specific tunnel server. The FEP could also tunnel individual clients, based on the user name or destination.
This is important to understand. Consumer VPN services protect your transmission from your location to their location, not from your location all the way to the destination application you're using. If you think about it, this makes sense: A consumer VPN service is operated by a completely different company than, for example, Facebook or your bank.
However, you've got no choice but to run TunnelBear's client software (unless you use Linux), which may concern some privacy-minded users, and there's no option to set up TunnelBear connections on routers or other devices. Last but not least, this tiny Canadian firm is now owned by U.S. antivirus giant McAfee, which may mean TunnelBear is subject to U.S. search warrants.
Second on our list of fast VPN protocol is L2TP. It is more similar to PPTP protocol but with added layer of encryption that makes is more powerful in terms of security. L2TP/IPSec is easy to setup and considerably delivers high-speed VPN experience from any internet-connected devices. It comes built-in to Microsoft Windows, Android, and Apple devices. However, its offering is not extended to open-source routers and consoles. L2TP/IPSec is also considered as fast secure VPN protocol as it supports 256-bit encryption packets. The use of L2TP/IPSec protocol is more in practice for commercial uses to secure all the outgoing and incoming communication. It also acts as an alternative fast VPN protocol where PPTP fail to perform due to firewalls.
Mobile Apps: If you’re going to spend money on a VPN service provider (or even if you use a free one, frankly), you should be able to get a consistent experience across all of your devices. Most prominent providers offer desktop and mobile solutions for individual users, and while corporate and school networks may be a bit behind the curve here, they’re catching up too. Make sure you don’t have to use two different VPNs with two different policies and agreements just because you want to secure your phone along with your laptop.
To verify that each service effectively hid our true IP address, we looked at a geolocation tool, DNS leaks, and IPv6 leaks. When connected to each service’s UK servers, we noted whether we could watch videos on BBC iPlayer, and using US servers we noted whether we could stream Netflix. We also visited the sites of Target, Yelp, Cloudflare, and Akamai to check whether our VPN IP addresses prevented us from accessing common sites that sometimes blacklist suspicious IP addresses.
A VPN (Virtual Private Network) is a technology that creates a private tunnel over the internet. All your online traffic is redirected to the VPN server. All data passing between your device and the VPN server you have connected to is securely encrypted. This means that your internet service provider (ISP) and anyone else spying on your traffic cannot see your data. Your ISP is still needed to connect you to the internet, but all it does is connect you to the VPN server. After that, it cannot see which other websites you visit or other internet resources you connect to. For the more techy of you out there, the VPN server acts as a proxy.
Layer Two Tunneling Protocol (L2TP) is a combination of PPTP and Layer 2 Forwarding (L2F), a technology developed by Cisco Systems, Inc. Rather than having two incompatible tunneling protocols competing in the marketplace and causing customer confusion, the Internet Engineering Task Force (IETF) mandated that the two technologies be combined into a single tunneling protocol that represents the best features of PPTP and L2F. L2TP is described in RFC 2661 in the IETF RFC Database.
Betternet Free VPN is a free multi-platform app that allows users to connect anonymously to the internet. A VPN or virtual private network sends your internet connection through a separate server meaning that any website you visit will not be able to track your location. This can be used for a number of reasons from accessing region-locked content to simply wanting to avoid being tracked. While many VPN services have an annual charge Betternet Free VPN does not. In this article you will discover why Betternet for Windows is one of the most comprehensive, secure and transparent VPN services around!
A popular VPN service, TorGuard has servers in over 50 countries and enables users to unblock websites and get around censorship. This ensures that wherever you are in the world, there is bound to be a TorGuard server near you. By default, the service enables users to make five simultaneous connections. This lets users run the service on all their devices. To better protect users, the service has a kill switch. However, this feature is not available on mobile devices. Likewise, a Domain Name System leak protection works on Windows and OS X.
Not all the VPN protocols work fast. It is not that VPN doesn’t work fast, but all the protocols are designed to fulfill specific needs of the users. We have already discussed the fastest VPN protocols used in our VPN speed test. We are now detailing more features about each protocol to give you more reasons to choose the best one that fits your specific needs.
MPPE provides only link encryption between the VPN client and the VPN server. It does not provide end-to-end encryption, which is data encryption between the client application and the server hosting the resource or service that is being accessed by the client application. If end-to-end encryption is required, IPSec can be used to encrypt IP traffic from end-to-end after the PPTP tunnel is established.

Price: proXPN has a free plan, which limits your transfer speeds to 300kpbs and restricts you to one exit location (Miami) in the United States. Premium accounts unlock support for PPTP (if you want to connect a mobile device or a router,) remove the transfer cap, and allows you to choose from any of the company’s other exit locations. Premium plans start at $10/mo, and you can read more about their pricing and plans here.
To verify that each service effectively hid our true IP address, we looked at a geolocation tool, DNS leaks, and IPv6 leaks. When connected to each service's UK servers, we noted if we could watch videos on BBC iPlayer, and using US servers we noted if we could stream Netflix. We also visited the sites of Target, Yelp, Cloudflare, and Akamai to check if our VPN IP addresses prevented us from accessing common sites that sometimes blacklist suspicious IP addresses.
The service has around a hundred servers around the world, in all continents. Server switching is facilitated on the line from just about anywhere. This feature is ideal for use by those who need to reach different locations or those who are in obscure places. Connection speed is relatively fast, with the service offering unlimited bandwidth. Albeit significant lag can be experienced during connection, such is resolved in just a few minutes.
However, you've got no choice but to run TunnelBear's client software (unless you use Linux), which may concern some privacy-minded users, and there's no option to set up TunnelBear connections on routers or other devices. Last but not least, this tiny Canadian firm is now owned by U.S. antivirus giant McAfee, which may mean TunnelBear is subject to U.S. search warrants.
Speedify the third and final free VPN service that we recommend thinking about signing up to. It's a little different than the two options above in that it's designed from the ground up to absolutely maximise your connection speed. So if you're on a laptop with ethernet and wifi connections, it'll utilize both to pull bits out of the internet to the max. If you're on a phone it can use your 4G and WiFi connections at the same time to do the same time - to maximise throughput of data, improving download speeds and render times. In our tests this all proved to be more than just hot air - it really did work to speed up our download and browsing speeds. At the same time it's doing all the things you'd want from a VPN, ecrypting and obscuring, so you're private, safe and anonymous. The catch here is that you only get 1GB of free data. You get 4GB in the first month but that drops down to 1GB after that which just isn't enough if you're planning to use it a lot.
When choosing your VPN, do your research and mind the legal aspects. Countries like Germany, France or Japan are cracking down on copyright infringement, while the members of the 14 Eyes treaty have draconian data retention laws and extensive surveillance. So, if you’re looking to maximize your privacy, you might want to avoid connecting to servers in those countries.
People love to travel because they want to experience the beauty of life. If you’re one of them, then your backpack should always be loaded. A high-speed VPN should be on your checklist as it gives you the free hand to access to all your local apps and websites when you are offshore. A fastest VPN connection not only offers global access to websites, but this travel companion safeguards you from online identity theft. So don’t forget to install a fast secure VPN app in your mobile when you plan your vacations.

Fortunately, there are some brave companies that are still trying to stay one step ahead of Netflix’s VPN catchers. Currently, Windscribe Pro is our top choice. The service delivers good speeds on its U.S. servers, and has a very simple approach to Netflix: Just select the “Windflix” connection from the desktop app or browser extension and you’re good to go. Windflix is still technically in beta, but it works well and there’s even a Windflix U.K. option if you’d like to experience Netflix from the other side of the pond.


It is a common misconception that VPN connections require a dial-up connection. They require only IP connectivity between the VPN client and VPN server. Some clients (such as home computers) use dial-up connections to the Internet to establish IP transport. This is a preliminary step in preparation for creating a tunnel and is not part of the tunnel protocol itself.
Compatibility – ExpressVPN is compatible with a wide range of devices and operating system. This includes Windows, OS X, Linux, and Chrome OS. In mobile phones and tablets, it is compatible with Android, iOS, Amazon Kindle Fire. It is also compatible with gaming and streaming consoles such as Amazon Fire TV, Chromecast, Apple TV, PlayStation 4, PlayStation 3, Xbox, Xbox One, and Roku. In short, I don’t think there is any other VPN provider that has such a wide cross-compatibility with different platforms.
Welcome to the CNET 2018 Directory of VPN providers. In this directory, we're taking a look at a few of the very best commercial VPN service providers on the Internet like CyberGhost, IPVanish, Buffered, Private Internet Access and others. Rather than looking at the wide range of free providers, which often have a lot of limits (and dubious loyalties), we are looking at those vendors who charge a few bucks a month, but put your interests first, rather than those of shadowy advertisers and sponsors. Our VPN rankings are based more than 20 factors including number of server locations, client software, dedicated and dynamic IP, bandwidth caps, security, logging, customer support and price. 
We’ll get to the implications of a VPN’s location in a moment, but first, let’s get back to our secure tunnel example. Once you’re connected to the VPN and are “inside the tunnel,” it becomes very difficult for anyone else to spy on your web-browsing activity. The only people who will know what you’re up to are you, the VPN provider (usually an HTTPS connection can mitigate this), and the website you’re visiting.
The first runs in the VPN client app on your computer, so if the VPN connection fails while the VPN client app is running, that VPN client app can turn off the computer or mobile device's internet connection. However, if your VPN connection has failed because the VPN client app itself crashed, then the kill switch may not work, and your IP and data may leak onto the internet.
Put simply, a Virtual Private Network, or VPN, is a group of computers (or discrete networks) networked together over a public network—namely, the internet. Businesses use VPNs to connect remote datacenters, and individuals can use VPNs to get access to network resources when they’re not physically on the same LAN (local area network), or as a method for securing and encrypting their communications when they’re using an untrusted public network.

Because it is impossible to update separate user accounts on separate servers for the same user simultaneously, most administrators set up a master account database at a domain controller or on a RADIUS server. This enables the VPN server to send the authentication credentials to a central authenticating device, and the same user account can be used for both dial-up remote access and VPN-based remote access.

The download speed indicates how fast data can be pulled from the server to you. Since the majority of online activity – like loading web pages or streaming videos – consists of downloads, most connections are designed to download much faster than they upload. Download speed is measured in megabits per second (Mbps) and, generally, the higher the number the faster the connection.

Setting up a Virtual Private Network is a straightforward process. It's often as simple as entering a username and sever address. The dominant smartphones can configure Virtual Private Networks using PPTP and L2TP/IPsec protocols. All major operating systems can configure PPTP VPN connections. OpenVPN and L2TP/IPsec protocols require a small open source application (OpenVPN) and certificate download respectively.
The solution is also able to bypass firewalls through stealth connections. Additional security is provided through an ad and malware blocker, which can be switched on and off. For those who enjoy torrenting, the software supports such process, with certain servers optimized for P2P networks. This is designed to keep high-speed browsing on other connections. However, the service warns users to keep torrenting activities confined to specific cities around the world.

CHAP is an improvement over PAP because the clear-text password is not sent over the link. Instead, the password is used to create a hash from the original challenge. The server knows the client’s clear-text password and can, therefore, replicate the operation and compare the result to the password sent in the client’s response. CHAP protects against replay attacks by using an arbitrary challenge string for each authentication attempt. CHAP protects against remote-client impersonation by unpredictably sending repeated challenges to the remote client throughout the duration of the connection.

Hi Douglas, I don't want you to publish my previous comment particularly, I'm not trying to attack their company, the comment was mainly for your information - given your comment about ease of use. I finally got it connecting after reinstalling both NordVPN and Avast, then adding exceptions, with all the previously mentioned config mods having been made. I installed the software on a Windows 10 machine, and it still required some mods, but was easier than Windows 7. cheers Nathan


RIP routers can also communicate routing information through triggered updates. Triggered updates occur when the network topology changes and updated routing information is sent that reflects those changes. With triggered updates, the update is sent immediately rather than waiting for the next periodic announcement. For example, when a router detects a link or router failure, it updates its own routing table and sends updated routes. Each router that receives the triggered update modifies its own routing table and propagates the change.
Servers – ExpressVPN has a large server network that spans more than 94 locations across the world. The total number of servers of ExpressVPN has crossed 2,000. You can connect to servers in available locations in a matter of mere seconds. All servers are encrypted with the AES 256 standard, ensuring the security of user traffic. With these servers, you can gain access to any website, no matter how strong a firewall has been put up to prevent user traffic from accessing it.
The VPN server provides a routed connection to the network to which the VPN server is attached. On a site-to-site VPN connection, the packets sent from either router across the VPN connection typically do not originate at the routers. The calling router (the VPN client) authenticates itself to the answering router (the VPN server), and, for mutual authentication, the answering router authenticates itself to the calling router.
The service supports Windows, Mac, Android and iOS devices, but manual connection through Linux, BlackBerry, Boxee Box, HP WebOS or DD-WRT is also possible. It likewise allows users to use up to five devices using the account. PureVPN’s proprietary gigabit network ensures uptime and extremely fast speeds. It offers unlimited bandwidth, which is ideal for users who like video streaming or playing online games.
And they manage to do all of this without sacrificing performance, offering one of the fastest download speeds (83 Mbps out of 100 Mbps) and the best 24/7 customer support in the industry. The only downside? It’s a little on the pricey side, with monthly plans starting between $6.67 and $12.95/mo. But it’s a small price to pay for excellent performance in almost every category.
IPVanish is one of the few providers that owns and operates its own network of servers, rather than rents servers out from third parties. This guarantees customers a sturdy, uncongested connection and better privacy. The IPVanish apps include an auto-select feature that connects you to the fastest available server in a given country or city. You can monitor upload and download speed in real time. Traffic is protected by 256-bit AES encryption, and a zero logs policy ensures that no usage data is ever recorded. A single subscription allows users to connect up to five devices at once. IPVanish is particularly popular with Kodi users due to its fast speeds, great privacy features and because it is easy to install on most devices popular with Kodi users including the Amazon Fire Stick.
The free tier gives you the Windows, Mac, iOS, Android and Amazon Fire TV/Firestick client software (and the beta Linux software, should you wish to try it); the Windflix feature to (try to) watch U.S. or U.K. Netflix streams; the Chrome, Firefox and Opera Windscribe browser extensions to block ads and trackers; a separate firewall built in to the Windows and macOS clients; and the ability to connect to VPN servers in 11 countries, mostly in Europe and North America.
Since we first recommended IVPN in the spring of 2018, the company has added automatic server selection to its desktop applications, bringing it in line with other top-performing VPN apps. Alternatively, when you click on the location at the bottom of the app, you’ll see a list of all of the global IVPN server locations, color coded by speed. At the top of the list is an option to connect to the fastest one, and once selected, the app remembers your preference through future disconnects and reboots. You can also use IVPN’s multihop servers to route your traffic through two VPN servers—a feature unique to IVPN among the services we tested—though we don’t think this step is necessary for most people, given the slower speeds you’ll likely experience.
Our Free VPN Service is built on the cornerstones of freedom of speech and a basic right to privacy – We believe that every individual should have access to the internet without fear of an invasion of these rights. You should be able to surf the web, download files, and chat to your friends freely without reprisal. The internet is a vast wealth of information which should be readily available without restrictions. With a great understanding of these rights and beliefs, we have created an all-encompassing VPN service that provides you with the security you deserve.
Internet connection has changed the lives of many people. Today, they are more than 3.5 billion in the world to connect on this large public network. Some Internet users connect to the Internet for entertainment, information sharing, information, watching videos, etc., and others for purely business reasons. In both cases, Internet users should always use a VPN to secure their connection and surf more freely and anonymously on the Internet.
TunnelBear is the undisputed best free VPN service available today. It's a serious VPN that's serious about customer satisfaction, privacy and security. So the upside is that you're getting a VPN that works, and can be trusted not to hold loads of data on you and sell you out at the earliest opportunity! The downside is that the free tier of TunnelBear only gets you 500MB bandwidth each month. That means for many people having it always-on will leave you caught short well before the end of the month, and absolutely rules out using it to stream endless episodes of Rick and Morty on Netflix. The free VPN tear at TunnelBear is certainly designed as a gateway to the paid tier which offers unlimited data but will cost you real money. If you're going to pay for a VPN we'd suggest getting a premium one like Express, but if you're only interested in a free option then TunnelBear is the one for you unless you need loads of bandwidth.
PureVPN has a huge choice of 750 servers in 141 countries and counting. The sheer volume of features, toggles, and tools they provide makes it a top contender for the advanced users. There is a stealth browsing mode, online banking security, secure FTP access, multiple protocols and more. They have server lists optimized for P2P and video streaming, so switching is easy.

ExpressVPN earns a spot on our list thanks to its feature-filled service that is easy to use for both technical and non-technical users. ExpressVPN consistently ranks as one of the fastest VPN providers in our official BestVPN Speed Test. This makes it a fantastic option for streaming HD content. Robust encryption keeps hackers at bay and no usage logs means the company can’t share your personal browsing data. With servers in plenty of countries around the world, “stealth” servers to help users in China bypass the firewall, and Smart Domain Name System (DNS) service that keeps streaming sites like Netflix running smoothly, you can see why ExpressVPN continues to impress our experts and remains one of our most popular VPN providers. Try ExpressVPN today with a 30-day, no-quibble, money-back guarantee.

From a feature-to-dollar standpoint, TunnelBear’s premium offering doesn’t beat out our two previous recommendations. StrongVPN and SurfEasy are better bets if you’re willing to pay. But, TunnelBear does offer a free tier, doesn’t maintain logs, and it is extremely easy to get up and running with their dead-simple apps for desktop and mobile users alike.


Security when connecting to public Wifi networks: Many people use public Wifi networks – You can find them in airports, cafes, bars and public libraries for example. People use these Wifi networks freely and without any forethought for their security. How do you know that network is secure? How do you know there isn’t someone attempting to break into that network? A VPN can be used to securely connect to a Wifi network and protect your data integrity. Learn More

We used to advise people to do banking and other important business over their cellular connection when using a mobile device, since it is generally safer than connecting with a public Wi-Fi network. But even that isn't always a safe bet. Researchers have demonstrated how a portable cell tower, such as a femtocell, can be used for malicious ends. The attack hinges on jamming the LTE and 3G bands, which are secured with strong encryption, and forcing devices to connect with a phony tower over the less-secure 2G band. Because the attacker controls the fake tower, he can carry out a man-in-the-middle attack and see all the data passing over the cellular connection. Admittedly, this is an exotic attack, but it's far from impossible.
