Translations:IPsec L2TP VPN server/1/en

Many operating systems support an L2TP/IPsec VPN out-of-the-box. By combining the confidentiality- and authentication services of IPsec (Internet Protocol security), the network tunneling of the Layer 2 Tunnel Protocol (L2TP) and the user authentication through pppd, administrators can define VPN networks across multiple, heterogeneous systems. This allows setting up a VPN across Android, Windows, Linux, MacOS and other operating systems without any commercial software requirements.
