In compulsory tunneling, the client computer places a dial-up call to a tunneling-enabled NAS at the ISP. For example, a corporation might have contracted with an ISP to deploy a nationwide set of FEPs. These FEPs can establish tunnels across the Internet to a tunnel server connected to the organization’s private network, thus consolidating calls from geographically diverse locations into a single Internet connection at the organization network.
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.
This is when the VPN uses a gateway device to connect to the entire network in one location to a network in another location. The majority of site-to-site VPNs that connect over the internet use IPsec. Rather than using the public internet, it is also normal to use career multiprotocol label switching (MPLS) clouds as the main transport for site-to-site VPNs.
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.
Password Authentication Protocol (PAP) is a clear-text authentication scheme. The NAS requests the user name and password, and PAP returns them in clear text (unencrypted). Obviously, this authentication scheme is not secure because a malicious user could capture the user's name and password and use it to get subsequent access to the NAS and all of the resources provided by the NAS. PAP provides no protection against replay attacks or remote client impersonation once the user's password is compromised.
ProtonVPN is a superb service provided by the developers of Proton Mail. It is a secure VPN provider that lets people use the service on an unlimited basis. This makes it perfect for privately surfing the web on a daily basis. On the downside, it throttles free-users’ bandwidth. This means that the free ProtonVPN service will not provide the speeds necessary for doing data-intensive tasks such as streaming in HD. ProtonVPN is a superb VPN that many people may find useful for unblocking censored news.

Using the methods above does not prevent unwanted traffic if a malicious Internet user is remotely controlling the VPN client computer. To prevent this, ensure that the VPN client computer has a firewall enabled (such as Internet Connection Firewall in Windows XP) and an anti-virus program installed and running with the latest virus signature file installed. These are also settings that can be enabled and enforced when using Network Access Quarantine Control.

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.
