Configuring the Network Mode on the SonicWALL Page 19

NAT with DHCP Client

NAT with DHCP Client is a networking mode that allows you to obtain an IP address for a specific
length of time from a DHCP server. The length of time is called a lease, which is renewed by the
DHCP server typically after a few days. When the lease is ready to expire, the client contacts the
server to renew the leas e. This is a common network configur ation for customers with cable or DSL
modems. You are not assi gned a specific IP address by your I SP.
Instructions for configuring NAT with DHCP Client mode begin on page 32.

NAT with L2TP Client

NAT with L2TP Client is a networking mode that allows you to connect to a remote L2TP server to
obtain IP address settings. L2TP (Layer 2 Tunneling Protocol) is a network protocol using IPSec to
encrypt transmitted data, and is only supported by Windows 2000. If yo u are running o ther ver sions
of Windows, you must use PPTP as your tunneling protocol.
Instructions for configuring NAT with L2TP Client mode begin on page37.

NAT with PPTP Client

NAT with PPTP Client is a networking mode supporting PPTP (Point to Point Tunneling Protocol) to
connect to a remote server. It uses Microsoft Point to Point Encryption (MPPE) to provide encry ptio n
of transmitted data. PPTP typically supports older Microsoft clients that require tunneling
connectivity or situations in which a tunnel passes through a firewall performing NAT.
Instructions for configuring NAT with PPTP Client begin on page 38.
