In other words, this feature will allow computers on a private network to establish outbound VPNs. On the client side, a common VPN setup is by design not a conventional VPN, but does typically use the operating system's VPN interfaces to capture a user's data to send through. This include virtual network adapters on computer OSes and specialized "VPN" interfaces on mobile operating systems.

The IPsec section contains example VPN Configurations that cover site to site IPsec configuration with some third party IPsec devices. If pfSense software is known to work in a site to site IPsec configuration with a third party IPsec device not listed, we would appreciate a short submission containing configuration details, preferably with screenshots where applicable.
IPSec VPN is a popular set of protocols used to ensure secure and private communications over Internet Protocol (IP) networks, which is achieved by the authentication and encryption of IP packets between two end-points.
IPsec versus MPLS. While there are several types of VPNs, enterprises generally use either an Internet Protocol security (IPsec) or Multiprotocol Label Switching (MPLS) VPN to connect their remote and mobile employees to data, apps, and other corporate resources. The terms “IPsec” and “MPLS” indicate the way each type of VPN transmits data. How does VPN tunneling work? To connect to the internet through a VPN tunnel, you'll first have to sign up with a virtual private network service, better known as a VPN. The VPN is the key to hiding your IP address and shielding your online activity from snoops. Before visiting websites, you'll log into your VPN provider’s service.

The two modes differ in the sense that the transport mode L2TP/IPSEC; General: Popular open-source VPN protocol with cross-platform capabilities: Basic VPN protocol. This is the first VPN protocol that was supported by Windows. Tunneling protocol that uses IPSec for security and encryption. L2TP works via UDP. Encryption strength: OpenVPN uses strong encryption via OpenSSL. A VPN allows you to use inherently non-private public Wi-Fi by creating an encrypted tunnel through which your data is sent to a remote server operated by your VPN service provider. The VPN server then sends the data to the site you’re seeking to connect with, encrypted and safe from the prying eyes of identity thieves and other cybercriminals.
