L2TP/IPsec (Layer 2 Tunneling Protocol with Internet Protocol Security): L2TP is not secure itself, so it's generally paired with the IPsec secure-networking standard. The combination of the two was once thought to be very secure when properly implemented, but some VPN services suggest that you use OpenVPN instead. L2TP/IPsec has native support in Windows, OS X/macOS, Android, Chrome OS and iOS. Most VPN services support it.
Jurisdiction – From the point of view of privacy, nothing is more important than the jurisdiction in which a VPN provider operates. VPN providers based in countries like the UK, the US, Canada, New Zealand, and Australia have to follow data retention laws and cooperate with agencies for surveillance purposes. However, if a VPN provider truly follows a zero-logging policy, then users can consider their privacy secure even if the VPN is based in one of the countries as above. Nonetheless, given the choice, you should avoid VPNs that fall in the jurisdiction of agencies notorious for their surveillance programs.
Required only when the VPN server is acting as a VPN client (a calling router) in a site-to-site VPN connection. If all traffic from TCP port 1723 is allowed to reach the VPN server, network attacks can emanate from sources on the Internet that use this port. Administrators should only use this filter in conjunction with the PPTP filters that are also configured on the VPN server.
But even if you know who’s behind your VPN, you shouldn’t trust a free one. A free service makes you and your data the product, so you should assume that any information it gathers on you—whether that’s an actual browsing history or demographics like age or political affiliation—is being sold to or shared with someone. For example, Facebook’s Onavo provides an encrypted connection to Onavo’s servers like any VPN, shielding you from the prying eyes of your ISP or fellow network users. But instead of promising not to examine, log, or share any of your traffic, Onavo’s privacy policy promises the opposite. Covering the service, Gizmodo sums it up well: “Facebook is not a privacy company; it’s Big Brother on PCP.” Facebook collects information about your device, other applications you use, and even “information and other data from your device, such as webpage addresses and data fields.” And the company “may combine the information, including personally identifying information, that you provide through your use of the Services with information about you we receive from our Affiliates or third parties for business, analytic, advertising, and other purposes.” That means Facebook can collect anything it wants, and sell it to anyone it wants.

For VPN connections, however, IP datagrams sent across the Internet can arrive in a different order from the one in which they were sent, and a higher proportion of packets can be lost. Therefore, for VPN connections, MPPE changes the encryption key for each packet. The decryption of each packet is independent of the previous packet. MPPE includes a sequence number in the MPPE header. If packets are lost or arrive out of order, the encryption keys are changed relative to the sequence number.

When you're using a public Wi-Fi network, even a password-protected one, a VPN is your best friend. That’s because using public hotspots can be rife with hazards. From man-in-the-middle attacks to Wi-Fi sniffing, there are many different hacking methods that snoopers use to intercept your Internet traffic and steal your social media or banking passwords, files and photos.
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.
Advanced leak protection – Perfect Privacy offers very secure apps to ensure you are protected against any and all leaks. In the Perfect Privacy review I discuss the three different levels of the kill switch and DNS leak protection. Users are also protected from IPv6 leaks because Perfect Privacy offers full IPv6 support across their server network (giving you both an IPv4 and IPv6 address for all your devices).

If you are interested in an added level of protection, there are intriguing gadgets called Tiny Hardware Firewalls. These devices range from about $30 to $70 and connect via a network port or a USB slot to your laptop. They make the initial network connection, and so your computer's communication is always blocked before it calls out to the internet.
Also important is the protocol the VPN service uses. Connecting to a VPN service using the OpenVPN protocol generally yields a faster, more reliable experience. Plus, OpenVPN is, as the name implies, open-source. That means it has been picked over for flaws and exploits by thousands of volunteers. If you're concerned about speed and security, selecting a service that supports OpenVPN and makes it available by default is important.
Although the diminishing online privacy of users has been a long-running theme in the digital world, the recent Facebook-Cambridge Analytica scandal was the first exposure of our fragile privacy on a global level. It is in these circumstances that the search for best VPN services has become our answer to the continually shrinking privacy and security of the average netizen.
Proxies are also widely used, and there is always the question about how they differ from VPNs. The purpose of both methods is to protect the identities of the users or to falsify a place. While they are different technologies, many VPN providers also offer proxies.A proxy is the type of computer system that functions as an intermediary for your connected device and your web connection. These servers also have their own IP addresses, so the transfers cannot be traced directly to your computer.

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.
All VPNs have to do some kind of logging, but there are VPNs that collect as little data as possible and others that aren’t so minimalist. On top of that, some services discard their logs in a matter of hours or days while other companies hold onto them for months at a time. How much privacy you expect from your VPN-based browsing will greatly influence how long you can stand having your provider maintain your activity logs—and what those logs contain.
Add to that the volume of add-ons offered by TorGuard, especially access to a 10Gbit network and static IP addresses which aren't likely to be blocked, and it's a very competitive service. It also has greatly expanded its collection of servers and because it is so focused on serving BitTorrent, it's clear that the company cares about how fast data moves through its network.
IPSec – Internet Protocol Security (IPSec) can be utilized with Layer 2 Tunneling Protocol (L2TP) or Internet Key Exchange version 2 (IKEv2). While it is not open source, it does do well in the performance category and can be used natively (without apps) on most operating systems. IPSec/IKEv2 may be the best protocol to use with some mobile devices (iOS), which do not work as well with OpenVPN.
Since it takes research to find out if a VPN service has a history of good or bad behavior, we’ve done the legwork to find the best VPN out there. In order to win our seal of approval, the service has to protect online privacy; allow you to keep anonymity; offer a good variety of locations from which to direct your traffic; offer fast, reliable performance; and provide an easy-to-use interface.

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.)
These services offer many ways to connect, including without the service's client software; support operating systems and devices, such as routers or set-top boxes, beyond just the "big four" operating systems (Windows, Mac, Android and iOS); have hundreds, or even thousands, of servers in dozens of countries; and generally let the user sign up and pay anonymously.
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.

Like ProtonVPN, the VPN service built in to the Opera web browser gives you an unlimited amount of free data per month. But its network download and upload speeds were awful (download speeds were 3 percent of the baseline speed), and it's not even a real VPN; it's just a browser-specific encrypted proxy service. (The OperaVPN mobile apps no longer work.)
The service’s no logs policy means that it does not store user online activity data and promises not to release them unless required by law, ensuring that your information is in safe hands. What sets this service apart from others is its refund policy. Users are able to use it for up to 10 hours or 10GB of bandwith and still get a refund, a far more generous policy than what others have to offer.
Whether you’re you’re sick of your ISP throttling your connection, you want to secure your browsing sessions while on the road, or you just want to download whatever the heck you want without the man on your back, there’s no substitution for a securely deployed Virtual Private Network. Now that you’re armed with the knowledge necessary to pick a good VPN (and with three solid recommendations at that), it’s time to secure your internet traffic once and for all.
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/
If you are interested in an added level of protection, there are intriguing gadgets called Tiny Hardware Firewalls. These devices range from about $30 to $70 and connect via a network port or a USB slot to your laptop.

In such scenarios, you don’t need a beastly VPN provider with massive bandwidth to secure your email, Facebook, and web browsing activities. In fact, the same home VPN server model we highlighted in the previous section will serve you just as well as a paid solutions. The only time you might consider a paid solution is if you have high-bandwidth needs that your home connection can’t keep up with (like watching large volumes of streaming video through your VPN connection).
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.
The country connections, meanwhile, matter most to those who want to spoof their location; however, non-spoofers should also make sure there are connections in their home country. If you live in Los Angeles, for example, and want access to American content, then you’ll need a VPN that provides U.S. connections. It won’t work to try and watch Amazon Prime Video over a Dutch VPN connection, because as far as Hulu’s concerned your computer is in the Netherlands.
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.
In addition, in a spoke and hub frame relay topology, the frame relay interface for the hub router must have a router priority set to 1 or greater and the frame relay interfaces for the spoke routers must have a router priority set to 0. Otherwise, the hub router, which is the only router that can communicate with all of the spoke routers, cannot become the designated router and adjacencies cannot form across the frame relay network.
Regardless of what country you are from, encryption remains the best route to online safety. A private VPN is the surest tool to provide that secure encryption. TorGuard provides quality privacy services in over 50 countries world wide. Our VPN service will help you keep your search habits and personal information secret, protect your IP address so websites can’t associate them with your browsing habits, hide your activity on public Wi-Fi hotspots to keep crooks out, bypass censorship to access blocked websites, keep you anonymous on Bittorrent and safeguard your right to online privacy. If you want to keep unscrupulous companies and people from seeing and intercepting your online activity and sensitive personal information, you need private VPN encryption.

The main drawback with VyprVPN is their connection log policies. They keep connection logs for 30 days, but usage/activity logs are never kept. Another slight drawback is that they do not permit torrenting on their network. But on a positive note, they are very honest and straightforward about their policies, unlike some VPNs that falsely claim to be “no logs”.
The student/worker. This person has responsibilities to attend to, and uses a VPN provided by their school or company to access resources on their network when they’re at home or traveling. In most cases, this person already has a free VPN service provided to them, so they’re not exactly shopping around. Also, if they’re worried about security, they can always fire up their VPN when using airport or cafe WI-Fi to ensure no one’s snooping on their connection. Photo by Ed Yourdon.
To send on a LAN or WAN link, the IP datagram is finally encapsulated with a header and trailer for the data-link layer technology of the outgoing physical interface. For example, when an IP datagram is sent on an Ethernet interface, the IP datagram is encapsulated with an Ethernet header and trailer. When an IP datagram is sent over a point-to-point WAN link such as an analog phone line or ISDN, the IP datagram is encapsulated with a PPP header and trailer.
The problem with anonymity is there are so many issues to consider—most of which are beyond the scope of this article. Has the government surreptitiously installed malware on your PC in order to monitor your activity, for example? Does the VPN you want to use have any issues with data leakage or weak encryption that could expose your web browsing? How much information does your VPN provider log about your activity, and would that information be accessible to the government? Are you using an anonymous identity online on a PC that you never use in conjunction with your actual identity?

Classless static routes are implemented using DHCP scope option 249. Using classless static routes, each DHCP client can be configured with the route to any destination on the network, and the subnet mask can be specified. Because each scope represents a physical subnet, the scope can be viewed as the start location for any message that is to be sent by a client to another subnet. The parameters used to configure option 249 are Destination, Mask, and Router. One or more static routes can be configured with option 249. All DHCP-enabled clients on the network can be provided with routes to all other subnets using option 249.


In the most recent round of testing, we've also looked at how many virtual servers a given VPN company uses. A virtual server is just what it sounds like—a software-defined server running on server hardware that might have several virtual servers onboard. The thing about virtual servers is that they can be configured to appear as if they are in one country when they are actually being hosted somewhere else. That's an issue if you're especially concerned about where you web traffic is traveling. It's a bit worrisome to choose one location and discover you're actually connected somewhere else entirely.
