Virtual private network (VPN) is a network architecture for virtually extending a private network (i.e. any computer network which is not the public Internet) across one or multiple other networks which are either untrusted (as they are not controlled by the entity aiming to implement the VPN) or need to be isolated (thus making the lower network invisible or not directly usable).

MPLS VPN is a family of methods for using Multiprotocol Label Switching (MPLS) to create virtual private networks (VPNs). MPLS VPN is a flexible method to transport and route several types of network traffic using an MPLS backbone. There are three types of MPLS VPNs deployed in networks today: 1. Point-to-point 2. Layer 2 (VPLS) 3.
A VPN service can log the user's traffic, although this depends on the VPN provider. [15] A VPN service does not make the user immune to cyberattacks. [15] A VPN service is not in itself a means for good Internet privacy. The burden of trust is simply transferred from the ISP to the VPN service provider. [16] [17] A VPN service is not a VPN.
Outline VPN is a free and open-source tool that deploys Shadowsocks servers on multiple cloud service providers. [1] [2] The software suite also includes client software for multiple platforms. Outline was developed by Jigsaw, a technology incubator created by Google. [3]
The process of setting up an L2TP/IPsec VPN is as follows: Negotiation of IPsec security association (SA), typically through Internet key exchange (IKE). This is carried out over UDP port 500, and commonly uses either a shared password (so-called " pre-shared keys "), public keys, or X.509 certificates on both ends, although other keying ...
