Detailed explanation-1: -Layer Two Tunneling Protocol (L2TP) is an extension of the Point-to-Point Tunneling Protocol (PPTP) used by internet service providers (ISPs) to enable virtual private networks (VPNs). To ensure security and privacy, L2TP must rely on an encryption protocol to pass within the tunnel.
Detailed explanation-2: -ExpressVPN As one of the best VPN services, ExpressVPN supports L2TP as a legacy protocol for Windows and macOS.
Detailed explanation-3: -IPsec is often used to secure L2TP packets by providing confidentiality, authentication and integrity. The combination of these two protocols is generally known as L2TP/IPsec (discussed below). The two endpoints of an L2TP tunnel are called the L2TP access concentrator (LAC) and the L2TP network server (LNS).
