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

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
