IPSec NAT-T enables IPSec peers to negotiate and communicate when they are behind a NAT. To use IPSec NAT-T, both the remote access VPN client and the remote access VPN server must support IPSec NAT-T. IPSec NAT-T is supported by the Windows Server 2003 Microsoft L2TP/IPSec VPN Client and by the L2TP/IPSec NAT-T Update for Windows XP and the L2TP/IPSec NAT-T Update for Windows 2000. During the IPSec negotiation process, IPSec NAT-T-capable peers automatically determine whether both the initiating IPSec peer (typically a client computer) and responding IPSec peer (typically a server) can perform IPSec NAT-T. In addition, IPSec NAT-T-capable peers automatically determine if there are any NATs in the path between them. If both of these conditions are true, the peers automatically use IPSec NAT-T to send IPSec-protected traffic.

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.
When it comes to servers, more is always better. More servers mean that you're less likely to be shunted into a VPN server that is already filled to the brim with other users. NordVPN, Private Internet Access, and TorGuard currently lead the pack with well over 3,000 servers each—NordVPN is at the forefront with 4,875 servers. But the competition is beginning to heat up. Last year, only a handful of companies offered more than 500 servers, now it's becoming unusual to find a company offering fewer than 1,000 servers.

A traditional VPN can affect the user experience when applied to wireless devices. It's best to use a mobile VPN to avoid slower speeds and data loss. A mobile VPN offers you a high level of security for the challenges of wireless communication. It can provide mobile devices with secure access to network resources and software applications on their wireless networks. It's good to use when you're facing coverage gaps, inter-network roaming, bandwidth issues, or limited battery life, memory or processing power.
Anonymous internet access: Anonymity is preferable for many when surfing the web. We do not like the idea of someone watching our every more and monitoring our actions. We have a basic right to privacy and free VPN will help you achieve this. Using the VPN service, you can enjoy a trouble-free private browsing session with no traceability. Learn More
Update: We’ve received some feedback that 10Mbps is too slow to get good test results. We would argue that 10Mbps is quite average for home internet across the world, and we run tests for average people.  While our tests might not be a good indication of speed if you’re paying for a 50 Mbps or 100 Mbps connection, the results are varied enough to get a statistically significant indication of overall performance. Furthermore, all the VPNs on the list officially offer unlimited bandwidth, so if you happen to be on an uncongested nearby server, chances are you’ll still be able to max out your available bandwidth. Finally, there is no point in having a fast VPN if it is unstable, doesn’t protect your privacy, doesn’t unblock the content you want, or doesn’t have a good range of servers to connect to. We excluded providers like TotalVPN which were very fast but had awful customer service, for example.

We always advise our readers to take speed tests with a grain of salt; too many factors are at play but believe me there’s no such thing as the “fastest VPN,” no matter how many companies claim. While reviewing VPNs, we test the internet speed using different tools that measure three essential elements; latency, download speeds, and upload speeds. We compare VPNs, keeping these three areas into mind.

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.

Agree expressvpn is an absolute winner, even though nordvpn has more than twice servers (around 5000) it still loses in download speed and therefore streaming. One remark I noticed when tested average speed of different vpns is that the closer your own location is to vpn server you choose the better the speed and it seems to be obvious. The only big cons for expressvpn is of course the price but it seems that the guys from the company knows the best can’t be cheap  I would also like to share a good source for online vpn comparison chart I have found, check it here https://www.vpnhint.com/vpn-comparison-chart/


So our advice is to not use a free VPN unless it really is for occasional, very casual use. For the odd IP-hopping use case, they can work. But if you're planning on using the VPN a lot and for streaming video etc we'd highly recommend going for one of the overall best VPN services - they're not free but they're also pretty cheap in the grand scheme of things.

Spies—and, more frequently, advertisers—can glean a lot about your movements online. By capturing your IP address, an observer can divine your approximate geographic location. With a VPN it's a different story. Because your web traffic appears to be coming from the VPN's server and not your computer or mobile device (yes, there are Android VPN apps and iPhone VPN apps), any observer will see the VPN server's IP address and not yours. That makes it much harder to correlate your movements across the web.

Among last year's VPN apps for Android, Private Internet Access had the least impact on downloads, reducing speeds by just 10.3 percent. However, Private Internet Access had an enormous impact on latency. If that's your primary concern, TorGuard is your best bet. That service only increased latency by 12.5 percent. In our upload test, Private Internet Access fared well but TorGuard less so.

VPN technology was developed as a way to allow remote users and branch offices to securely access corporate applications and other resources. To ensure safety, data travels through secure tunnels, and VPN users must use authentication methods -- including passwords, tokens or other unique identification procedures -- to gain access to the VPN server.
We’ve shown you how to roll your own VPN using Hamachi, and even how to set up Privoxy to secure your web browsing once you have your personal VPN set up. Hamachi isn’t the only option: you can also download and configure OpenVPN (a free SSL VPN) on your own home server,, or if you have a router that supports it, enable OpenVPN on your home router so you can connect back to it when you’re abroad. Combined with Privoxy, you get the privacy and anonymity benefits of a VPN without spending a dime.
VPN connections help provide the required security to enable the network segment of the human resources department to be physically connected to the intranet. In this configuration, a VPN server can be used to separate the network segments. The VPN server does not provide a direct routed connection between the corporate intranet and the separate network segment. Users on the corporate intranet with appropriate permissions can establish a remote access VPN connection with the VPN server and gain access to the protected resources. Additionally, all communication across the VPN connection is encrypted for data confidentiality. For those users who are not authorized to establish a VPN connection, the separate network segment is hidden from view.
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.

Yet Mullvad is worth a look because it's extremely private and secure. It asks nothing about you when you sign up. Instead, it assigns you a random number that will be your combined username and password. You don't have to provide an email address, and you can pay by mailing cash to the company's headquarters in Sweden. (Mullvad also takes credit cards, PayPal, bitcoin and wire transfers.)


As the size of the link state database increases, memory requirements and route computation times increase. To address this scaling problem, OSPF divides the network into areas (collections of contiguous networks) that are connected to each other through a backbone area. Each router only keeps a link state database for those areas that are connected to the router. Area border routers (ABRs) connect the backbone area to other areas.

Even when browsing online in the comfort of your own home, using a VPN is a pretty good idea. For instance, you may want to buy your little nephew a birthday gift online without being bombarded with toy truck ads for next six months. Or perhaps you need to do a quick research of health clinics without attracting your employer’s attention. If you live in the US, you may simply want to know that your ISP will not be able to sell your entire browsing history to the highest bidder.


In many cases, each of these offices also have LANs. But how do the LANs connect? For some very specialized solutions, companies lease private lines to connect the offices. That can be very expensive. Instead, most companies opt to geographically connect separated private LANs over the public internet. To protect their data, they set up VPNs between offices, encrypting the data as it traverses the public internet.
Extensible Authentication Protocol (EAP) is a PPP authentication protocol that allows for an arbitrary authentication method. EAP differs from the other authentication protocols in that, during the authentication phase, EAP does not actually perform authentication. Phase 2 for EAP only negotiates the use of a common EAP authentication method (known as an EAP type). The actual authentication for the negotiated EAP type is performed after Phase 2.
To perform our fastest VPN speed test, experts at ReviewsDir have carefully taken a lot of essential factors into account. This includes setting up uniform criteria where each VPN service fighting for the spot in the fastest VPN service list will go through rigorous tests. Since VPN speed issues have a lot to contribute with the location, we have tested our fast VPN performance test from all the seven continents; America, Europe, Asia, and Africa.
One of the most common types of VPNs used by businesses is called a virtual private dial-up network (VPDN). A VPDN is a user-to-LAN connection, where remote users need to connect to the company LAN. Another type of VPN is commonly called a site-to-site VPN. Here the company would invest in dedicated hardware to connect multiple sites to their LAN though a public network, usually the Internet.
In conjunction with information security experts at The New York Times (parent company of Wirecutter), we reached out to our finalists with questions about their internal security practices. We asked how they handled internal security access, how they communicated securely with customers, in what ways they collected reports on security bugs, and of course whether their statements on logging policies matched their marketing and privacy policies. We also considered which companies had public-facing leadership or ownership, and which ones openly supported projects and organizations that promoted Internet security and privacy. (For a full breakdown of trust and VPNs, check out the section above.)
Even if a company is at fault for deceptive marketing practices, it still has to comply with legal requests for whatever information it does have. Jerome told us, “In the U.S., however, there is a big difference between a request for data regularly stored for business purposes and a demand that a company retain information. VPN providers are not required to keep records just in case law enforcement might need them some day.” That means many companies could provide a list of their customers, but if they practice what they preach when it comes to no-logging policies, innocent customers looking for privacy shouldn’t get swept up in these requests.
Second, what are the acceptable terms of use for your VPN provider? Thanks to the popularity of VPNs with torrent users, permissible activity on specific VPNs can vary. Some companies disallow torrents completely, some are totally fine with them, while others won’t stop torrents but officially disallow them. We aren’t here to advise pirates, but anyone looking to use a VPN should understand what is and is not okay to do on their provider’s network.
One of the most popular VPN services in the market, HideMyAss has a myriad of features that are sure to attract anyone who wants online anonymity. It uses a variety of servers that work with any operating system or mobile device. Aside from PPTP and OpenVPN protocols, the service supports L2TP, which is more difficult to block. Ideal for getting around censorship and firewalls.
The app likewise prevents websites from collecting users’ private data, allowing for safer and more secure web browsing. To make things even better, the solution automatically connects whenever an unsecure Wi-Fi connection is detected, ensuring constant protection. It connects to the nearest server, resulting in optimum speeds. But one can also connect manually and be able to choose a preferred server.
We believe privacy and security are fundamental human rights, so we also provide a free version of ProtonVPN to the public. Unlike other free VPNs, there are no catches. We don't serve ads or secretly sell your browsing history. ProtonVPN Free is subsidized by ProtonVPN paid users. If you would like to support online privacy, please consider upgrading to a paid plan for faster speeds and more features.
Kodi is becoming the next biggest platform for streaming world’s content, and it’s not possible that binge-watchers are unaware of this gigantic media center. Kodi community would relate the only reality that Kodi addons are geo-restricted; you need to be in the specific region to stream your desired or better to say all the best Kodi addons. Kodi is all about streaming content using addons, means if you’re planning to use a Kodi VPN to stream addons, make sure the VPN should be uber-fast.
Jurisdiction – ZenMate is based in Germany, which is a country with one of the freest Internet in Europe. Online freedom is protected in the country and it does not have a history of persecution against bloggers and social media activists. Nonetheless, it is still part of the 14 Eyes alliance, which implies that users should be careful when considering ZenMate.
TorGuard is incorporated in St. Kitts and Nevis, and operates out of offices mostly in the US. But most people shouldn’t be worried about the legal jurisdiction of their VPN’s offices—we detail the reach of government surveillance above. In short, we think a privacy-focused VPN with public leadership that can be trusted not to collect information about their customers is a better choice in any country, rather than an opaque company run from the most liberty-ensuring country on the planet.
Hi Sandra. I just gave VyprVPN a go and didn’t have any problems running the iPlayer. Try clearing your cache and cookies (you only need to clear all BBC and iPlayer related ones if you don’t want to clear them all) and run in an Incognito/Private browser window. That may fix it. Alternatively, it’s possible you just got unlucky and were assigned an IP blacklisted by the BBC.

VPNs can make your browsing private, but that doesn’t necessarily mean you’re anonymous. VPN services can and do log traffic (even the ones that say they don’t log do need to log some information, or they wouldn’t be able to function properly), and those logs can be requested by the authorities. Think of a VPN as being like curtains: people can’t peek through your curtains if you’ve got them closed, but curtains won’t hide your house.


Tests are run on connections ranging from 10 Mbps to 30 Mbps connections. Our testers are in different locations around the world, but we never plot the results of speed tests from different locations together. The internet in Buenos Aires will almost always be slower than in Berlin, for instance, so that wouldn’t be a fair comparison. We do add multiple tests to the same plot even if we ran them days or weeks apart, so long as they are from the same location.
When you're away from home or the office and you connect to the internet, you'll most often be doing so via Wi-Fi provided by your hotel or the restaurant, library, or coffee shop you're working out of in that moment. Sometimes, the Wi-Fi has a password. Other times, it will be completely open. In either case, you have no idea who else is accessing that network, and therefore, you have no idea who might be snooping on your traffic.

It is possible for some background services to send information across that initial, unsecured connection before the VPN loads. To be fair, the risk is relatively minor for most usage profiles. If you're establishing a connection automatically to your corporate server, you will definitely want to check with your IT team about how they want you to set things up.

Here you should remember that before being sent and received over the Internet, any data needs to first be split into packets. To ensure each data packet stays secure, a VPN service wraps it in an outer packet, which is then encrypted through a process called encapsulation. This exterior packet keeps the data secure during the transfer, and it is the core element of the VPN tunnel. When the data arrives at the VPN server, the outer packet is removed to access the data within, which requires a decryption process.


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.
Google Chrome has a built-in task manager to help users find out the runtime statistics of each tab. When you open up too many tabs and what to kill some of them to release more memory or CPU, task manager is a great tool. Let’s dive in. Open Task Manager You can access Task Manager by clicking on the three-dot icon on the right side of the address bar, going down to More Tools and then select Task Manager.

We hope that our take on fastest VPN service providers paid off well, and we were able to share all the important details on the subject. A little recap; VPN is undoubtedly a great invention, but when it comes to delivering high speed, a lot of VPNs fails. We have discussed many essential factors above that will help you with your search of high-speed VPNs. Remember, bandwidth is your biggest enemy in VPN speed also, and to give it a headshot requires a fast secure VPN installed on your PC and device.Throughout our fast VPN speed test, we have tested a dozen of VPNs, but if we have to recommend a single VPN only, then we would suggest you go with ExpressVPN – the all-rounder VPN!


It usually relies on either Internet Protocol Security (IPsec) or Secure Sockets Layer (SSL) to secure the connection. However, SSL VPNs can also be used to supply secure access to a single application, rather than an entire internal network. Some VPNs also provide Layer 2 access to the target network; these will require a tunneling protocol like PPTP (Point-to-Point Tunneling Protocol) or L2TP (Layer 2 Tunneling Protocol) running across the base IPsec connection.

That depends. VPN use is legal in most countries, but, according to VPN provider CyberGhost, VPN use is illegal in the United Arab Emirates, Turkey, China, Iran, North Korea, Saudi Arabia, and Russia. Vladimir Putin has recently banned VPN use in Russia. Also, be aware that the so-called proxy server alternative to VPNs is also illegal in many countries, which consider any form of IP spoofing to be illegal, not just those services labeled as VPN.


Hello Nathan, We are sorry for all the inconvenience you've experienced. Bunch of different factors might interfere with how VPN works: antivirus systems, firewalls, router settings, previous VPN services installed play their role just to name a few. Your mentioned behavior is uncommon, in most cases couple of mouse clicks is enough to get our apps up and running; however sometimes additional troubleshooting is required. This is why our customer support team is available 24/7, they aim to provide our clients with the best possible experience and help in any way we can. Please don't hesitate and reach out to them in case of any future issue.
A VPN client on a remote user's computer or mobile device connects to a VPN gateway on the organization's network. The gateway typically requires the device to authenticate its identity. Then, it creates a network link back to the device that allows it to reach internal network resources -- e.g., file servers, printers and intranets -- as though the gateway is on the network locally.
In addition to hiding your online activity from a snooping government it’s also useful for hiding your activity from a snooping Internet Service Provider (ISP). If your ISP likes to throttle your connection based on content (tanking your file downloads and/or streaming video speeds in the process) a VPN completely eliminates that problem as all your traffic is traveling to a single point through the encrypted tunnel and your ISP remains ignorant of what kind of traffic it is.
We spent more than 130 hours researching 32 VPN services, testing 12, interviewing the leadership of five, and consulting information security and legal experts. We found that a VPN shouldn’t be your first step toward online security, but for protecting your info on public Wi-Fi (and in some other cases), IVPN is the most trustworthy provider that offers fast, secure connections and easy setup.

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.


The service uses Advanced Encryption Standard with a 256-bit key, a common method employed by VPN services. Connections are protected using 2048-bit public key encryption. For privacy, the service offers a malware detection software. What is good about the software is that it can be downloaded and used without providing any personal information. This holds as long as you use the free version of the software and never contact customer support.
When we test VPNs, we generally start with the Windows client. This is often the most complete review, covering several different platforms as well as the service's features and pricing in depth. That's purely out of necessity, since most of our readers use Windows (although this writer is currently using a MacBook Air). We currently use a Lenovo ThinkPad T460s laptop running the latest version of Windows 10. We periodically upgrade to a newer machine, in order to simulate what most users experience.
