The initial PPP payload is encrypted and encapsulated with a PPP header to create a PPP frame. The PPP frame is then encapsulated with a modified GRE header. GRE is described in RFC 1701 and RFC 1702 in the IETF RFC Database and was designed to provide a simple, general purpose mechanism for encapsulating data sent over IP networks. GRE is a client protocol of IP using IP protocol 47.


This awesome Malaysian VPN provider has an excellent free service. Although users are limited to just three server locations (Singapore, the Netherlands, and Canada), users get a whopping 2GB per month of free use at up to 80Mbps. When reviewing hide.me, we found the lack of server locations means it isn’t good for unblocking content from all over the world. If you need US or UK servers, please look elsewhere. On the plus side, this VPN has a strong privacy policy and provides robust encryption to keep your data secure.
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.
IPVanish is one of the most recognisable names among all the VPN services out there. They've been going for years and if you've read about VPNs in the past you've probably seen some of their ads! IPVanish certainly isn’t going after the budget market here but it's still a bit cheaper than ExpressVPN. Like Express, IPVanish doesn’t offer a free trial (although there is a seven day money back guarantee if the service doesn’t live up to your expectations). It promises to be the world’s fastest VPN, with more than 40,000 IP addresses, 850 servers in 60 countries, unlimited peer to peer sharing and up to five simultaneous connections. That's certainly a bonus over ExpressVPN which only offers three connections at a time - IPVanish could be the better option for you if you want to get the whole family on one plan, for example. There’s a no logging policy, too, which means the service isn’t gathering stacks of data about what you’re doing.
An OSPF-routed network can be subdivided into areas, which are collections of contiguous networks. All areas are connected together through a common area called the backbone area. A router that connects an area to the backbone area is called an area border router (ABR). Normally, ABRs have a physical connection to the backbone area. When it is not possible or practical to have an ABR physically connected to the backbone area, administrators can use a virtual link to connect the ABR to the backbone.

There was a time when using a VPN required users to know about the built-in VPN client for Windows or universal open-source solutions such as OpenVPN. Nowadays, however, nearly every VPN provider has its own one-click client that gets you up and running in seconds. There are usually mobile apps as well to keep your Android or iOS device secure over public Wi-Fi.

Trust.Zone offers inconsistent speeds that vary considerably from one server to the other. Users might find it excellent for certain locations like the UK and Germany, but not fast enough for others. The privacy and security features of Trust.Zone are its strongest attributes, making it a great option for users seeking protection at acceptable speeds.


As we’ve mentioned, free doesn’t always mean ‘free’. Given the sensitive nature of your personal information, it’s tough to trust any company that are willing to waive a charge. The best free secure VPN will keep your information safe, without outrageous limitations to their speeds and features. Essentially, trust is the most important aspect, and you could end up being burned if you go with a dodgy provider.
ProtonVPN is available on all your devices including PC, MacOS, mobile, and even your router. A secure internet connection which you can trust is essential every day - for your PC at home, for your mobile device on the road, or your workstation at the office. ProtonVPN works on Windows, macOS and Android via our application, or on iOS, using any OpenVPN client.
TorGuard was consistently one of the fastest services we tested. When we averaged three tests performed at different times of the week with Internet Health Test, TorGuard was the fastest service when connecting in the UK and Asia, the second fastest in the US, and the third fastest in Central Europe. OVPN was the next most consistent, but that company’s small network doesn’t have any servers in Asia, and it ranked fifth in the UK. Our top pick, IVPN, was the third most consistently fast after TorGuard and OVPN. However, we tested with each app’s default settings—since we expect most people won’t change them—and TorGuard’s default 128-bit encryption gives it an advantage in speed tests over VPNs that default to 256-bit encryption, as most services do. Still, we think 128-bit encryption is fine for most people who prioritize speed, and TorGuard’s consistency makes it a good value as our budget pick.

There is a PPTP control connection between the IP address of the PPTP client using a dynamically allocated TCP port and the IP address of the PPTP server using the reserved TCP port 1723. The PPTP control connection carries the PPTP call control and management messages that are used to maintain the PPTP tunnel. This includes the transmission of periodic PPTP Echo-Request and PPTP Echo-Reply messages to detect a connectivity failure between the PPTP client and PPTP server. PPTP control connection packets consist of an IP header, a TCP header, a PPTP control message, and a data-link trailer and header as shown in the following figure:
A powerful VPN service, SaferVPN is very useful in hiding users’ IP addresses. It also allows access to blocked websites or safely share information. Privacy is also ensured as the service uses high security protocols. It offers a unique Automatic Wi-Fi Security feature which instantly activates a secure and encrypted VPN connection as soon as someone’s device connects to an unsecured Wi-Fi connection — automatically protecting them from public Wi-Fi threats. Likewise, it features single-click applications for Windows, Mac, iOS, Android and Chrome.
We're not cryptography experts, so we can't verify all of the encryption claims providers make. Instead, we focus on the features provided. Bonus features like ad blocking, firewalls, and kill switches that disconnect you from the web if your VPN connection drops, go a long way toward keeping you safe. We also prefer providers that support OpenVPN, since it's a standard that's known for its speed and reliability. It's also, as the name implies, open source, meaning it benefits from many developers' eyes looking for potential problems.
First I just want to say what a great website you have created, very informative. I am using Avast VPN on a Windows computer and Google Chrome browser. Without a VPN I am getting download speeds up to 180 MB, and 24 MB up, using Ookla to test speeds. Using Avast VPN drops that to 40-60 MB down and 2-3 MB up, and I have tried using multiple locations from Miami to Atlanta, NY, Chicago and Jacksonville. Miami and NY are classed as P2P. My location is S Florida. When I download torrents my speed falls drastically. With one torrent downloading I get 6 MB down and up. 2 torrents simultaneously 2.5 MB down and 1.4 MB up. 3 torrents 2 MB down and 1.5 up, and 4 torrents 1 MB down and up. I have conducted dozens of tests over the course of the day to get an average of the speeds. I had previously used Private Internet Access, which was faster at the beginning of my one year subscription, but the speeds deteriorated towards the end of that one year subscription to speeds similar to Avast’s. Do you have any suggestions for a fastest VPN for streaming and torrenting? I only download torrents once or twice a month.
Trust.Zone offers inconsistent speeds that vary considerably from one server to the other. Users might find it excellent for certain locations like the UK and Germany, but not fast enough for others.

The software supports Windows, Mac, iOS and Android devices. It also has plugins for browsers such as Chrome and Opera. This feature basically protects any device that can run a browser. Installation takes only seconds and does not require additional tweaking. The app’s Vigilant Mode prevents data from leaking while TunnelBear is reconnecting. The solution can also disguise VPN traffic as normal HTTPS traffic. As for security, the platform provides a list of Wi-Fi network that can be trusted.
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.
If your location limits you to use certain website and also stops you from streaming, in this case you need to install vpn software in your device which will enable you to unblock those websites and makes streaming easier anywhere around the globe. It will act as a shield to protect you from cyber goons. VPN is a tool which changes your virtual location as well as keeps your privacy protected. It is necessary to choose the vpn which is according to your need. Fast vpn service helps you in choosing the most remarkable vpn according to your need whether you want vpn for streaming, corporate business or personal use.
Tip for Chrome, Firefox, and Opera users: A feature called WebRTC can, in some Web browsers, inadvertently cause your true IP address to leak out even when you’re connected via a great VPN. WebRTC assists with peer-to-peer connections, such as for video chatting, but could be exploited in some cases. You can manually disable this function in Firefox, or use an extension to block most instances of it in Chrome or Opera. For more details and instructions, check out Restore Privacy.

Remote access data encryption does not provide end-to-end data encryption. End-to-end encryption is data encryption between the client application and the server that hosts the resource or service being accessed by the client application. To get end-to-end data encryption, use IPSec to help create a secure connection after the remote access connection has been made.
Central America isn’t the first place you’d think of when it comes to cutting edge technology, but NordVPN is up there with the best VPN services in 2018. It has 1015 servers in 59 countries, supports up to six devices simultaneously, runs 2048-bit encryption and has a feature list including an automatic kill switch, dedicated IP addresses, strong DNS leak protection and the ability to pay in Bitcoin. For relatively short connections performance was superb, although we did notice a little latency creeping in from time to time for very long distance connections. However, browsing remained snappy and performance wasn’t degraded significantly. We’d recommend hunting the site for its free trial and if you like it, signing up for the 3-year plan which is currently going for just $99!
We recommend against using any so-called free VPN. Free VPN services tend to be significantly slower than their premium counterparts. Their servers are usually congested and the apps often impose bandwidth limits or data caps. Server selection is more limited as well. Besides speed, free VPNs often use shady practices to make money, such as collecting your browsing data to sell to third parties and injecting ads into browsers. Some even carry malware payloads to infect your device.
The only downsides to Private Internet Access are that you can't select your own username — you've got to stick with an assigned random ID — and that you've occasionally got to reinstall a balky driver in Windows. (There's a button to do this.) Selecting Private Internet Access as our VPN service of choice was almost a no-brainer, but because it's based in the U.S., anyone wary of the FBI may want to consider another service.
 Return Policy: “Many issues can contribute to sub-optimal performance (ISP, location, censorship, settings, etc.). The TunnelBear team goes to exceptional lengths to satisfy users who experience sub-optimal performance or the occasional outage. However, TunnelBear does not offer financial reimbursement due to these issues.” In other words, they don’t offer refunds.
For the formal testing, we used an HP EliteBook X360 1020 G2 notebook, an Asus ZenPad S8 tablet (for Avira Phantom VPN) and a Samsung Galaxy Note 8 phone (for Speedify). Wi-Fi and Ethernet connections were provided by a 200-Mbps cable broadband line. Each time we connected to a VPN service, we recorded how long it took to get online and noted how many times the service disconnected us.
Among the most critical is how to communicate and exchange information securely between employees sitting at multiple locations. Here is where a VPN or a Virtual Private Network proves to be very handy. It is a fast, reliable, and secure way to exchange information across computer networks, and an excellent, secure mode of communication from remote locations.
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.
They left a vunerability up for 3 years. Never bothered to do anything about it and never bothered to see if anyone took advantage of the vulnerability.So either they're flat out lying and knew they were being hacked and couldn't do anything about it or it's actually a back door they put there purposely. Can someone explain Googles behavior makes any sense?
That said, many VPN providers are based outside the US, which complicates enforcement. Jerome continued: “Users can file complaints in a local jurisdiction, and local data protection laws may have more effective enforcement mechanisms. For example, privacy and confidentiality of communications are fundamental rights in the European Union. Data protection authorities in EU-member states are empowered to handle complaints brought by individuals and then provide users with information about the outcome of any investigation. But it is unclear how effective any of these remedies will be.”

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.

Since VPNs route your traffic through another network, you can also make it appear as if it’s coming from another location. That means if you’re in Sydney, Australia, you can make your traffic appear to come from New York City. This is useful for certain sites that block content based on your location (like Netflix). It also allows some people (we’re looking at you, Australians) have to deal with insanely high import taxes on software that see them paying twice (or more) what US consumers pay for the same products.


StrongVPN is a great choice, as it meets the needs of both power users and casual users alike. Prices start at $10 a month and drop quickly, when you purchase a year of service at a time, to $5.83 a month. The ease of setup is fantastic–if you’re new to VPNs and/or don’t have extra time to fuss with manual settings, you can just download their setup app for Windows, OS X, iOS, and Android to automate the setup process. If you want a more granular control or need to manually configure devices like your router, you can follow one of their many guides for different operating systems and hardware to do it manually.
Hello smith, to name a few fastest free VPN providers, Windscribe and Hide.me are the best in the business. Irrespective of what a free VPN can do to your online security, but there’s no denying that these two VPN providers have no impact on the speed of the internet. Windscribe gives you 11 different server, while Hide.me gives you 3 different servers for free.

Every user is going to have slightly different VPN needs, and the best way to pick the ideal VPN service is to take careful stock of what your needs are before you go shopping. You may even find you don’t need to go shopping because home-grown or router-based solutions you already have are a perfect fit. Let’s run through a series of questions you should ask yourself and highlight how different VPN features meet the needs highlighted by those questions.
However, network performance is another thing entirely. First, keep in mind that if you're using a VPN, you're probably using it at a public location. That Wi-Fi service is likely to range in performance somewhere between "meh" and unusable. So, just the fact that you're remotely working on a mediocre network will reduce performance. But then, if you connect to a VPN in a different country, the connection between countries is also likely to degrade network performance.

Cost: There are two plans here; Premium and Gold, but only the latter supports VPN while the other is just their DNS service. UnoTelly Gold costs $7.95/month if you buy it every month, but there are three other options if you want to purchase it for three months, six months, or one year. Those prices, respectively, are $6.65/month, $6.16/month, and $4.93/month (each, of course, being paid for in one lump sum). You can try it free for eight days through this link.
Many VPN services also provide their own DNS resolution system. Think of DNS as a phone book that turns a text-based URL like "pcmag.com" into a numeric IP address that computers can understand. Savvy snoops can monitor DNS requests and track your movements online. Greedy attackers can also use DNS poisoning to direct you to bogus phishing pages designed to steal your data. When you use a VPN's DNS system, it's another layer of protection.
