Network tunneling is a method that enables the secure transfer of data from one network to another. Tunneling is a technique frequently used in virtual private networks (VPNs). Tunneling works by encapsulating packets and enveloping them inside other packets. (Packets are little chunks of data that can be reassembled at their destination into a larger file.)
In tunneling, as the packets move through the tunnel, they are encrypted and secure. For transmission, private network data and protocol information are encased in public network transmission units. The units appear to be public data, allowing them to be sent via the Internet. Packets can reach their intended destination thanks to encapsulation. Decryption and decapsulation take place at the destination.
Tunneling is enabled via a variety of protocols, including:
Point-to-Point Tunneling Protocol (PPTP): PPTP ensures the security of proprietary data even when it is communicated via public networks. An Internet service provider can provide authorized customers with access to a private network known as a virtual private network. Because it is being built in a tunneled environment, this is a "virtual" private network.
Layer Two Tunneling Protocol (L2TP): This tunneling protocol combines the use of PPTP and Layer 2 forwarding.
Tunneling is a method of communicating over a private network while passing via a public network. This is especially handy in a business situation and includes security measures such as encryption choices.
NOTE: Betternet employs a proprietary technological protocol that is very similar to Open VPN but with superior performance and functionality. Because Betternet configures every option automatically, our application is incompatible with PPTP, SSTP, L2TP, or any other network tunneling protocol that requires manual configuration.
