The IPsec protocol provides very strong encryption to data exchanged between the VPN server and with the VPN client machine. IPsec stands for Internet Protocol security. So we use another protocol called IPsec in conjunction with L2TP.
By default L2TP does not provide strong encryption or authentication by itself. L2TP or Layer 2 Tunnelling Protocol is a tunnelling protocol which originated by the merger of Microsoft (PPTP) and Cisco L2F.
Using RRAS as VPN remote users can connect to their company organisation networks internally and securely over public internet. Microsoft RRAS server and VPN client supports PPTP, L2TP, IPSec, SSTP and IKEv2 based VPN connections. So using RRAS we can convert a regular Windows Server as VPN server. It is a suite of network services in the Windows Server family that enables a server to perform the services of a conventional router.It is also a Windows proprietary server role, that supports remote user or site to site connectivity by using virtual private network or dial-up connections. The full form of RRAS is Routing and Remote Access Service. Microsoft servers provided with RRAS server roles for implementing such remote access services. A VPN can also be used to connect computers to isolated remote computer networks that is usually inaccessible, by using the Internet or another intermediate network. A VPN service masks our ISP IP so your online actions are virtually untraceable. A VPN is short form of virtual private network, which gives us a privacy, anonymity and security over public internet.
