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 lease. This is a common network configuration for customers with cable or DSL
modems. You are not assigned a specific IP address by your ISP.
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 you are running other versions
of Windows, you must use PPTP as your tunneling protocol.
Instructions for configuring NAT with L2TP Client mode begin on page 37.
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 encryption
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.
Configuring the SonicWALL in Standard Mode
This section describes configuring the SonicWALL in Standard mode. You must have a single, static
IP address to begin configuration. Follow the instructions below.
TIP Be sure to have your network information including your WAN IP address, subnet mask, and DNS
settings ready. This information is obtained from your ISP.
1. Open a Web browser and enter the default SonicWALL IP address, 192.168.168.168, in the
Location or Address field.
2. The Login window appears. Enter admin in the User Name field, and password in the Password
field.
3. Click Cancel on the initial Installation Wizard page to cancel the wizard.
4. Click Network in the General section.
5. Select Standard from the Network Addressing Mode menu.
6. Enter 192.168.168.1 in the SonicWALL LAN IP Address field.
7. Enter 255.255.255.0 in the LAN Subnet Mask field.
8. Enter your WAN router or default gateway IP address in the WAN Gateway (Router) Address field.
If you have DSL or cable, your WAN router is typically located at your ISP.
9. Enter your DNS IP address(es) in the DNS Server fields.
10. Click Update. Once the SonicWALL is updated, you must restart the SonicWALL for the changes
to take effect.
