SonicWALL TZ 190 Manuale Utente

Chapter 51: 

The SonicWALL security appliance can terminate L2TP-over-IPsec connections from incoming 
Microsoft Windows 2000 and Windows XP clients. In situations where running the SonicWALL 
Global VPN Client is not possible, you can use the SonicWALL L2TP Server to provide secure 
access to resources behind the SonicWALL security appliances. 

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 is supported on Microsoft Windows 2000 Operating System. 

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. 

For more complete information on configuring the L2TP Server, see the technote
