Developed by Institute of Electrical and Electronics Engineers, VLANs allow multiple tagged LANs to share common trunking. VLANs frequently comprise only customer-owned facilities. Whereas VPLS as described in the above section (OSI Layer 1 services) supports emulation of both point-to-point and point-to-multipoint topologies, the method discussed here extends Layer 2 technologies such as 802.1d and 802.1q LAN trunking to run over transports such as Metro Ethernet.
Hi Martin, the list of VPN providers that we have highlighted in the table above are the 5 fastest paid VPN providers. PureVPN and NordVPN is amongst the list that are very much affordable, but that doesn’t mean other VPN providers are expensive. Their increased online security and increased internet speed makes other VPN providers’ price to differ.
Logging Policy – The logging policy of any VPN provider is the first thing you should read before you decide to purchase it. This is especially true for users whose primary objective for purchasing a VPN is to maintain and protect their privacy. Many VPN providers deliberately write overly complicated and ambiguous privacy policies to confuse users. Stay far away from such VPN providers as these are most likely trying to hide their actual practices for how they treat their users’ privacy. 

Hotspot Shield VPN works in most countries, but that doesn’t mean it’s always legal to use a VPN in a specific country. If you have any doubts about the legality of using a VPN in a certain country, always consult a qualified lawyer because laws can change quickly. If you’re still unsure, then it’s best to play it safe and abide by the most conservative guidelines of a country.
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.
A “kill switch” goes by many names, but the term describes VPN software that shuts off all network traffic in and out of your computer if the encrypted connection fails. A hiccup in your Wi-Fi or even with your ISP can cause a VPN to disconnect, and if you then maintain an unsecure connection—especially if the VPN software doesn’t alert you that it’s no longer protecting your traffic—that wipes out all the benefits of your VPN. We considered kill switches to be mandatory. And although we looked for apps that made it easy to add rules about when to activate kill switches, we considered special config files or manual firewall tweaks to be too complex. (iOS doesn’t support any kill-switch features; we address a few iOS-specific problems that apply to all VPN services in a separate section.)
But for a company that bills itself as "the world's fastest VPN," Hide.me was kind of mediocre, with our download speeds dropping to a third of the non-VPN baseline. Free users are limited to 2GB of monthly data and can connect to servers in only three countries; either of those limitations would be more acceptable if the network speeds were faster.

It is possible to create Windows-based L2TP connections that are not encrypted by IPSec. However, this does not apply to a VPN connection because the private data being encapsulated by L2TP is already not encrypted. Non-encrypted L2TP connections can be used temporarily to troubleshoot an L2TP over IPSec connection by eliminating the IPSec authentication and negotiation process.
We also like how easy it is to connect, and how clear and accessible the settings are, on all platforms when using the IVPN app. (ChromeOS has an option to use a less-secure VPN protocol with most providers, including IVPN. But TorGuard, our budget pick, supports the more secure OpenVPN on Chromebooks and tablets.) If you do want to tweak some settings, IVPN has easy-to-understand checkboxes for most options. For example, the kill switch (labeled “firewall”) has an easy on/off toggle. Anytime it’s on and the app is open, all traffic in and out of your computer will cut off if you forget to connect to the service or the secure connection drops for some reason.
If you're using a service to route all your internet traffic through its servers, you have to be able to trust the provider. Established security companies, such as F-Secure, may have only recently come to the VPN market. It's easier to trust companies that have been around a little longer, simply because their reputation is likely to be known. But companies and products can change quickly. Today's slow VPN service that won't let you cancel your subscription could be tomorrow's poster child for excellence.
We didn’t find any problems when we tested other aspects of TorGuard’s performance. Each time we checked our location via IP address, it accurately resolved to the location of a TorGuard server. Neither our true IP address nor our location was exposed when we tested for DNS leaks and IPv6 leaks. TorGuard runs its own DNS servers—a requirement for all the VPNs we tested—so the routing that happens when you go to a website isn’t released to your ISP, Google, or anyone else. And since TorGuard doesn’t support IPv6, the app disables it completely, just like IVPN.
VPNs, or Virtual Private Networks, are a quick and easy solution to making your computer appear to be coming from a different location. They accomplish this by creating a virtual network that routes all of your PC or smartphone’s network traffic through an encrypted tunnel and out the other side, making it seem to the world that you’re actually in whatever location the VPN server is located. This can help you bypass geographic restrictions, avoid censors, or keep you (relatively) anonymous online.

Use IP packet filters on the VPN remote access policy profile to discard both inbound traffic on the VPN connection that has not been sent from the VPN client and outbound traffic that is not destined to the VPN client. The default remote access policy, named “Connections to Microsoft Routing and Remote Access server in Windows Server 2003” has these packet filters configured and enabled by default.


One of the most important skills any computer user should have is the ability to use a virtual private network (VPN) to protect their privacy. A VPN is typically a paid service that keeps your web browsing secure and private over public Wi-Fi hotspots. VPNs can also get past regional restrictions for video- and music-streaming sites and help you evade government censorship restrictions—though that last one is especially tricky.
Think about it this way: If your car pulls out of your driveway, someone can follow you and see where you are going, how long you are at your destination, and when you are coming back. They might even be able to peek inside your car and learn more about you. With a VPN service, you are essentially driving into a closed parking garage, switching to a different car, and driving out, so that no one who was originally following you knows where you went.
