Checking Link LEDs
The WAN Link LED and the LAN Link LED light up when the SonicWALL is properly
connected to the LAN and WAN ports of the computer and the modem.
Important:
You may have to switch the red crossover cable with the standard grey cable
to establish a connection. Switch cables until a link is established. Switching between a
crossover cable and a standard cable does not damage your SonicWALL or your computer.
Setting Up a Management Station
To access the SonicWALL Management interface, you must set up a PC on your LAN to be in
the same subnet (network) as the SonicWALL. This computer is called the “Management
Station”.
Accessing the SonicWALL from your PC
The SonicWALL is preconfigured to have an IP address of 192.168.168.168. To contact the
SonicWALL for the first time, you must change the Management Station (your PC) IP address
to 192.168.168.X where X is any number between 0 and 254, except 168 which is the
SonicWALL IP address. In this section, you configure your Management Station IP address to
192.168.168.200.

Setting up your Management Station
All management functions on the SonicWALL are performed from a Web browser-based user
interface. Management can be performed from any computer connected to the LAN port of the
SonicWALL. The computer used for managing the SonicWALL is referred to as the Management
Station.
The following steps describe how to configure the Management Station TCP/IP settings in order
to initially access the SonicWALL. It is assumed that the Management Station can access the
Internet through an existing connection.
Note
: If you are running Windows XP, consult your operating system documentation for
configuring TCP/IP settings.

Configuring TCP/IP Settings
The SonicWALL is pre-configured with the IP address “192.168.168.168". During the initial
configuration, it is necessary to temporarily change the IP address of the Management Station
to one in the same subnet as the SonicWALL. For initial configuration, set the IP address of the
Management Station to "192.168.168.200".
Make a note of the Management Station current TCP/IP settings. If the Management Station
accesses the Internet through an existing broadband connection, the TCP/IP settings are
helpful when configuring the IP settings of the SonicWALL.

Connecting the SonicWALL to the Network
The following diagram illustrates how the SonicWALL is connected to the network:
Important
: Before installing the SonicWALL on your network, register your appliance on the
user registration web site located at http://www.mysonicwall.com. It is strongly recommended
that you create a user account before installing your SonicWALL and register any services and
upgrades for your SonicWALL.
As a registered user, you have access to the SonicWALL
technical support website.
Configuring your SonicWALL to Access the Internet
Three common network configurations,
NAT Enabled, NAT with PPPoE Client,
and
NAT
with DHCP
Client are included in this chapter. For more network configurations, please refer
to Chapter 2,
Installation
, of the SonicWALL Internet Security Appliance User’s Guide.
Network Address Translation (NAT) Enabled
Using NAT to set up your SonicWALL eliminates the need for separate IP addresses for all
computers on your LAN. It is a way to conserve IP addresses available from the pool of IPv4
addresses for the Internet. If you do not have enough individual IP addresses for all computers
on your network, you can use NAT for your network configuration.
Essentially, NAT translates the IP addresses in one network into those for a different network.
As a form of packet filtering for firewalls, it protects a network from outside intrusion from
hackers by replacing the internal (LAN) IP address on packets passing through a SonicWALL
with a “fake” one from a fixed pool of addresses. The actual IP addresses of computers on the
LAN are hidden from outside view.
Instructions for configuring
NAT Enabled Mode
begin on page 24.
NAT with PPPoE Client
Page 25 / 88
Page 24
NAT with PPPoE Client
is a network protocol that uses Point to Point Protocol over Ethernet
to connect with a remote site using various Remote Access Service products. This protocol is
typically found when using a DSL modem with an ISP requiring a user name and password to
log into the remote server. The ISP may then allow you to obtain an IP address automatically
or give you a specific IP address.
Instructions for configuring
NAT with PPPoE Client
mode begin on page 31.
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 onpage 36.
Configuring the SonicWALL in NAT (Network Address Translation)
Enabled Mode
This section describes configuring the SonicWALL appliance in the NAT mode. If you are
assigned a single IP address by your ISP, follow the instructions below. If you do not want to
use
NAT Enabled
mode for your network, please follow the installation instructions for
Standard
mode in the SonicWALL Internet Security Appliance User’s Guide.
Note
: 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.
Accessing the Wizard
1.
Open a Web Browser. Then type the default SonicWALL IP address, "192.168.168.168",
into the Location or Address field in the Web browser.
Note
: Your Web browser must be Java-enabled and support HTTP uploads in order to fully
manage SonicWALL. Internet Explorer 5.0 and above as well as Netscape Navigator 4.0 and
above are recommended
.
