To work around this problem, instead of having the client create a new default route when a connection is made, administrators can configure the client’s routing table with specific routes that direct packets to the organization’s network over the VPN connection. While connected to the intranet, the client can obtain Internet access using the default route that points to the Internet. This configuration is known as split tunneling.
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.
Two networks can be connected over an intranet using a site-to-site VPN connection. This type of VPN connection might be necessary, for example, for two departments in separate locations, whose data is highly sensitive, to communicate with each other. For instance, the finance department might need to communicate with the human resources department to exchange payroll information.
For two years running, Private Internet Access has performed the best in our network tests and remained the cheapest full-fledged VPN service we've tried. It has more than 3,000 servers worldwide, supports platforms ranging from Windows and Mac to open-source routers, and lets you customize your tunneling and encryption protocols. You can pay in bitcoin, and you don't have to provide your real name.
The best VPN services offer a robust balance of functions, server location, connectivity protocols, and price. Some are great for occasional use, others are geared towards surrounding location constraints that companies place on their apps and services, and others are focused on people who download a lot of content and want some privacy while they do.
 Return Policy: “Many issues can contribute to sub-optimal performance (ISP, location, censorship, settings, etc.). The TunnelBear team goes to exceptional lengths to satisfy users who experience sub-optimal performance or the occasional outage. However, TunnelBear does not offer financial reimbursement due to these issues.” In other words, they don’t offer refunds.
VPN services, while tremendously helpful, are not foolproof. There's no magic bullet (or magic armor) when it comes to security. A determined adversary can almost always breach your defenses in one way or another. Using a VPN can't help if you unwisely download ransomware on a visit to the Dark Web, or if you foolishly give up your data to a phishing attack.
