With the single-adapter model, also known as the NBMA model, the network for the frame relay service provider (also known as the frame relay cloud) is treated as an IP network and the endpoints on the cloud are assigned IP addresses from a designated IP network ID. To ensure that OSPF traffic is received by all of the appropriate endpoints on the cloud, the frame relay interface must be configured to send unicast OSPF announcements to all of the appropriate endpoints. For the server running Routing and Remote Access, this is done by designating the interface as an NBMA network and adding OSPF neighbors.
Free anonymous VPN. Using the web anonymously can provide the confidence that your information is safe. The idea of someone following our every digital move in order to make a profit is not acceptable to us. We value anonymity and don’t believe in sacrificing value in order to achieve it. Using our services is like cleaning up the digital footprints so that no one can retrace your steps.
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.
Latency: This is closely tied to proximity, but is also affected by the amount of traffic on the networks between you and the VPN server. Latency measures the time it takes to send and receive a request from a server, also called ping time. Many VPN apps will allow you to see which server offer the least latency, usually measured in milliseconds. If not, you can connect to the server and use a terminal or command prompt to ping a website and view the time.
If you’re unsure about whether you should get a VPN, check out our post that explains what a VPN is and when one makes sense as a privacy and security tool. But most people leave their privacy and security vulnerable in ways that can be addressed with methods other than signing up for a VPN—methods that are potentially more effective. If you have a drafty house with paper-thin walls and halogen light bulbs, you’d get far more value out of every dollar by sealing up cracks, insulating, and switching to LEDs than you would by putting solar panels on your roof. Similarly, before you rush to sign up for a VPN subscription, you should consider these other ways to up your privacy game.
Some countries don't have the same protections for freedom of press, speech, and expression that most democratic countries have. In fact, some regimes resort to oppressive measures to monitor and take action against those they see as threats to the government. People who dare to stand up have to take extra precautions to protect their communications. Journalists and researchers also send messages containing data that some people may want to try very hard to intercept.
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.
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.
Bandwidth restrictions might not have been a big deal in the pre-streaming era, but now that everyone is streaming videos, music, and more, the bandwidth burns up really fast. Avoid VPNs that impose bandwidth restrictions unless the bandwidth restrictions are clearly very high and intended only to allow the provider to police people abusing the service.
When we ran our recent Hive Five on VPN service providers, we heard from VPN providers begging to be included, angry CEOs who claimed their company was maliciously left out, and others accusing some of the contenders of illegal or unethical behavior. We took at look at the poll and the claims, and while there’s no definitive proof the poll was gamed, we decided to come up with our own top five, based on our own research rather than reader feedback, that are great whether you’re the privacy advocate, the student, or the downloader.
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.
A client running the Microsoft Windows XP or Windows Server 2003 operating systems uses a DHCPINFORM message after the connection to request the DHCP Classless Static Routes option. This DHCP option contains a set of routes that are automatically added to the routing table of the requesting client. This additional information is available only if the Windows Server 2003 DHCP server has been configured to provide the DHCP Classless Static Routes option and if the VPN server has the DHCP Relay Agent routing protocol component configured with the IP address of the DHCP server.
In short, it's time to start thinking about protecting your personal information. That's where virtual private networks, or VPNs, come in. These services use simple software to protect your internet connection, and they give you greater control over how you appear online, too. While you might never have heard of VPN services, they are valuable tools that you should understand and use. So who needs a VPN? The short answer is that everyone does. Even Mac users can benefit from a VPN.
