IPsec is often used to secure L2TP packets by providing confidentiality, authentication and integrity checks. Compared to PPTP, which only establishes a single tunnel between the two end points, L2TP supports the use of multiple tunnels. L2TP (Layer Two Tunneling Protocol) is a combination of the Point-to-Point Tunneling Protocol (PPTP) and Layer 2 Forwarding (L2F). QNAP NAS supports L2TP/IPsec, PPTP and OpenVPN connections and you can select which one to use. Enable L2TP/IPsec, PPTP or OpenVPN services.
