The first time you log into your SonicWALL appliance, the
Setup Wizard
is launched automatically. To launch the Setup Wizard
at any time from the management interface, click the Wizards
button in the top right corner, and select Setup Wizard
.
The Setup Wizard helps you configure the following settings:
Using NAT to set up your SonicWALL eliminates the need for public 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. NAT also allows you to conceal the addressing scheme of your network. 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.
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.

Office Gateway
- Provide secure access for my wired and wireless users.

Tip
|
It is very important to choose a password which cannot be easily guessed by others.

Select the appropriate
Time Zone
from the Time Zone
menu. The SonicWALL’s internal clock is set automatically by a Network Time Server on the Internet. Click Next
.

You can choose:
|
•
|
Static IP
, if your ISP assigns you a specific IP address or group of addresses.
|
|
•
|
DHCP
, if your ISP automatically assigns you a dynamic IP address.
|
|
•
|
PPPoE
, if your ISP provided you with client software, a user name, and a password.
|
|
•
|
PPTP
, if your ISP provided you with a server IP address, a user name, and password.
|
DHCP
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.
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.
NAT with PPTP Client
mode uses Point to Point Tunneling Protocol (PPTP) to connect to a remote server. It supports older Microsoft implementations requiring tunneling connectivity.

The
LAN
page allows the configuration of the SonicWALL LAN IP Addresses
and the LAN Subnet Mask
.The SonicWALL LAN IP Addresses
are the private IP address assigned to the LAN port of the SonicWALL. The LAN Subnet Mask
defines the range of IP addresses on the LAN. The default values provided by the SonicWALL work for most networks. If you do not use the default settings, enter your preferred private IP address and subnet mask in the fields. Click Next
.

|
The
Optional-SonicWALL DHCP Server
window configures the SonicWALL DHCP Server. If enabled, the SonicWALL automatically configures the IP settings of computers on the LAN. To enable the DHCP server, select Enable DHCP Server
, and specify the range of IP addresses that are assigned to computers on the LAN.
|
If
Disable DHCP Server
is selected, you must configure each computer on your network with a static IP address on your LAN. Click Next
.
(SonicWALL wireless security appliances only) Select whether or not you want to configure Wi-
If Protected Access (WPA) security:

WPA/WPA2 Mode
- WPA is the security wireless protocol based on 802.11i standard. It is the recommended protocol if your wireless clients support WPA also.

|
Connectivity
- Caution! This mode offers no encryption or access controls and allows unrestrained wireless access to the device.
