Developed by Institute of Electrical and Electronics Engineers, Virtual LANs (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.
For local VPN issues, you have a couple of options. First, consider installing VPN software on your router and not using a VPN on your local machines. Alternatively, many VPN services offer browser plug-ins that only encrypt your browser traffic. That's not ideal from a security perspective, but it's useful when all you need to secure is your browser information.
Ideally, every VPN service provider would subject itself to independent audits to verify that it logs and operates as it claims. Right now, audits aren’t common practice in the VPN industry, though there’s a push to change that. Joseph Jerome, policy counsel at the Center for Democracy & Technology, told us about that group’s efforts to bring transparency to the VPN industry: “We would like to see security audits released publicly so security researchers can review them and attest to their veracity, as well as learn from the issues being identified.” The few companies we found that currently performed these types of audits had other dismissal-worthy failings, despite their valiant efforts toward transparency. And while such reports may increase your confidence when you're shopping, there’s no guarantee that an audit makes a VPN service trustworthy: In other industries, conflicts of interest have led auditors and rating agencies (PDF) to miss or ignore major problems.
After you choose your VPN, you must install and maintain it correctly to enjoy all the benefits a VPN can provide. In addition to using a sufficiently long key length, you must properly secure keys and access to VPN concentrators. If you store your keys in plaintext files on Internet-connected computers, all the bits of key length in the world won't help you if someone compromises those computers. You should also change your shared base keys on a regular basis, preferably every 3 months. This practice limits your exposure if a key is compromised.
PureVPN has servers in more than 140 countries and can be very inexpensive if you pay for two years up front. It also lets you "split-tunnel" your service so that some data is encrypted and other data isn't. But PureVPN was at or near the back of the pack in almost all of our 2017 performance tests. In October 2017, the U.S. Department of Justice disclosed in a criminal complaint that PureVPN had given the FBI customer logs in reference to a cyberstalking case, which kind of negates the entire point of using a VPN.
Routers – When you install the VPN on your router, all the devices that connect to your router will be using the encrypted VPN tunnel – without the need to install VPN software on each device. The router will only count as one VPN connection under your subscription, even if there are numerous devices using the router’s encrypted VPN connection. There are some important considerations before you do this – see my popular VPN router guide for setup tips.
While you're connected to a VPN, all your network traffic passes through this protected tunnel, and no one—not even your ISP—can see your traffic until it exits the tunnel from the VPN server and enters the public internet. If you make sure to only connect to websites secured with HTTPS, your data will continue to be encrypted even after it leaves the VPN.
VPNs also only do so much to anonymize your online activities. If you really want to browse the web anonymously, and access the dark web to boot, you'll want to use Tor. Unlike a VPN, Tor bounces your traffic through several server nodes, making it much harder to trace. It's also managed by a non-profit organization and distributed for free. Some VPN services will even connect to Tor via VPN, for additional security.
This again singles out NordVPN from the rest, as it boasts the largest server database in the marketplace. However, things do not just end here; you also receive multiple protocol support, which includes PPTP, L2TP/IPSec, OpenVPN, and IKEv2. Moreover, you have native apps for all platforms/devices, along with manual setup guides and built-in VPN routers. This comes in handy for configuring a secure connection around your house.
It should come as no surprise, then, that Australia is a market ripe for VPN providers. A VPN, or virtual private network, encrypts a device’s internet traffic and routes it through an intermediary server in a location of the user’s choosing. This can allow Australians to access content that’s geolocked in their own country. It can also provide a private tunnel through which to use P2P filesharing applications.
The number and distribution of those servers is also important. The more places a VPN has to offer, the more options you have to spoof your location! More importantly, having numerous servers in diverse locales means that no matter where you go on Earth you'll be able to find a nearby VPN server. The closer the VPN server, the better the speed and reliability of the connection it can offer you. Remember, you don't need to connect to a far-flung VPN server in order to gain security benefits. For most purposes, a server down the street is as safe as one across the globe.
Buffered VPN doesn't disclose much about the size of its network, but the 30-day money back guarantee means that you can take their service for a test drive and really get a feel for how well it performs for you. The company lost a few points from us because they do keep some connection information. They gained points for their client support, unlimited bandwidth, and generous number of simultaneous sessions allowed.
