Configuring L2TP Servers and VPN Client Access

VPN > L2TP Server

The Dell SonicWALL network security appliance can terminate L2TP-over-IPsec connections from incoming Microsoft Windows or Google Android clients. In situations where running the Global VPN Client is not possible, you can use the Dell SonicWALL L2TP Server to provide secure access to resources behind the firewall.

You can use Layer 2 Tunneling Protocol (L2TP) to create VPN over public networks such as the Internet. L2TP provides interoperability between different VPN vendors that protocols such as PPTP and L2F do not, although L2TP combines the best of both protocols and is an extension of them.

L2TP supports several of the authentication options supported by PPP, including Password Authentication Protocol (PAP), Challenge Handshake Authentication Protocol (CHAP), and Microsoft Challenge Handshake Authentication Protocol (MS-CHAP). You can use L2TP to authenticate the endpoints of a VPN tunnel to provide additional security, and you can implement it with IPsec to provide a secure, encrypted VPN solution.
