An Introduction to Zones and Interfaces
Zones split a network infrastructure into logical areas, each with
its own set of usage rules, security services, and policies. Most
networks include multiple definitions for zones, including those
for trusted, untrusted, public, encrypted, and wireless traffic.
Some basic (default) zone types include:
The X1 and X0 interfaces are preconfigured as WAN and LAN
respectively. The remaining ports (X2-X6) are also LAN ports by
default, however, these ports can be configured to meet the
needs of your network, either by using basic zone types (WAN,
LAN, WLAN, DMZ, VPN) or configuring a custom zone type to
fit your network requirements (Gaming Console Zone, Wireless
Printer Zone, Wireless Ticket Scanner Zone, and more).
WAN—Untrusted resources outside your local network.
LAN—Trusted local network resources.f
X1 WAN
WLAN—Local wireless network resources originating from
SonicWALL wireless enabled appliances.
Hotel / Home Office
DMZ—Local network assets that must be accessible from the
WAN zone (such as Web and FTP servers).
VPN—Trusted endpoints in an otherwise untrusted zone, such
as the WAN.
The security features and settings that zones carry are
enforced by binding a zone to one or more physical interfaces
(such as, X0, X1, or X2) on the SonicWALL TZ 210 series
appliance.

SonicWALL Wireless Firewalling
When a wireless device uses an access point to communicate
with a device on another subnet or on a completely different
network, traffic between the devices is forced to traverse the
network gateway. This traversal enables Unified Threat
Management (UTM) services to be enforced at the gateway.
Standard practice for wireless firewalling (where one wireless
client is communicating with another) bypasses many of the
critical UTM security services. The illustration below shows the
standard practice for wireless firewalling.
SonicWALL addresses this security shortcoming by managing
the SonicPoint access points from the UTM appliance. This
allows complete control of the wireless space, including zone
enforcement of security services and complete firewalling
capabilities, as shown in the illustration below.

create a new network segment on this interface such as a
DMZ or secondary LAN, this value should be set to Static.
Enter a static IP Address for the interface. For private and
semi-private network segments, any private static IP
address such as 10.10.20.1 is appropriate. Ensure that the
static IP address you choose does not conflict with any
currently existing interfaces. The newly created interface
appears in the Interfaces list. You may now connect the
appropriate network resources to this interface.
TZ_210_GSG.book Page 25 Thursday, November 13, 2008 7:41 PM

TZ_210_GSG.book Page 29 Thursday, November 13, 2008 7:41 PM
5.
Click on the Advanced tab.
Address Objects
Address Objects are one of four object classes (Address, User,
Service, and Schedule) in SonicOS Enhanced. Once you define
an Address Object, it becomes available for use wherever
applicable throughout the SonicOS management interface. For
example, consider an internal Web server with an IP address of
67.115.118.80.
6.
7.
8.
Configure the other settings on the Advanced tab as
explained below:
•
In the TCP Connection Inactivity Timeout (minutes)
field, set the length of TCP inactivity after which the
access rule will time out. The default value is 15
minutes.
•
In the UDP Connection Inactivity Timeout (minutes)
field, set the length of UDP inactivity after which the
access rule will time out. The default value is 30
minutes.
•
In the Number of connections allowed (% of
maximum connections) field, specify the percentage
of maximum connections that is allowed by this access
rule. The default is 100%.
•
Select Create a reflexive rule to create a matching
access rule for the opposite direction, that is, from your
destination back to your source.
Click on the QoS tab to apply DSCP marking to traffic
governed by this rule.
Click OK to add the rule.
Rather than repeatedly typing in the IP address when
constructing Access Rules or NAT policies, you can create an
Address Object to store the Web server’s IP address. This
Address Object, “My Web Server,” can then be used in any
configuration screen that employs Address Objects as a
defining criterion.
Available Address Object types include the following:
•
Host – Define a single host by its IP address.
•
Range – Define a range of contiguous IP addresses.
•
Network – Network Address Objects are like Range
objects in that they comprise multiple hosts, but rather than
being bound by specified upper and lower range delimiters,
the boundaries are defined by a valid netmask.
•
MAC Address – Allows for the identification of a host by its
hardware address.
•
FQDN Address – Fully Qualified Domain Names (FQDN)
Address Objects allow for the identification of a host by its
domain name, such as www.sonicwall.com.
SonicWALL TZ 210 Series Getting Started Guide Page 29
TZ_210_GSG.book Page 30 Thursday, November 13, 2008 7:41 PM

in the Starting IP Address and Ending IP Address
fields.
- For Network, enter the network IP address and
netmask in the Network and Netmask fields.
- For MAC, enter the MAC address in the MAC Address
field.
- For FQDN, enter the domain name for the individual
site or range of sites (with a wildcard) in the FQDN
field.
Click OK.
Tip: SonicOS Enhanced provides a number of default
Address Objects that cannot be modified or deleted.
You can use the default Address Objects when creating
a NAT policy, or you can create custom Address
Objects to use. All Address Objects are available in the
drop-down lists when creating a NAT policy.
Creating an Address Object
The Network > Address Objects page allows you to create
and manage your Address Objects. You can view Address
Objects in the following ways using the View Style menu:

Network Address Translation
Configuring NAT Policies
The Network Address Translation (NAT) engine in SonicOS
Enhanced allows users to define granular NAT policies for their
incoming and outgoing traffic. By default, the SonicWALL
security appliance has a preconfigured NAT policy to perform
Many-to-One NAT between the systems on the LAN and the IP
address of the WAN interface. The appliance does not perform
NAT by default when traffic crosses between the other
interfaces.
NAT policies allow you to control Network Address Translation
based on matching combinations of Source IP address,
Destination IP address, and Destination Services. Policy-based
NAT allows you to deploy different types of NAT simultaneously.
The following NAT configurations are available in SonicOS
Enhanced:
You can create multiple NAT policies on a SonicWALL running
SonicOS Enhanced for the same object – for instance, you can
specify that an internal server uses one IP address when
accessing Telnet servers, and uses a different IP address for all
other protocols. Because the NAT engine in SonicOS Enhanced
supports inbound port forwarding, it is possible to access
multiple internal servers from the WAN IP address of the
SonicWALL security appliance. The more granular the NAT
Policy, the more precedence it takes.

Inbound Port Address Translation via WAN IP Address
Before configuring NAT Policies, you must create all Address
Objects that will be referenced by the policy. For instance, if you
are creating a One-to-One NAT policy, first create Address

This section describes how to configure a One-to-One NAT
policy. One-to-One is the most common NAT policy used to
route traffic to an internal server, such as a Web server. Most of
the time, this means that incoming requests from external IP
addresses are translated from the IP address of the SonicWALL
security appliance WAN port to the IP address of the internal
Web server. The following example configuration illustrates the
use of the fields in the Add NAT Policy procedure. To add a
One-to-One NAT policy that allows all Internet traffic to be
routed through a public IP address, two policies are needed:
one policy for the outbound traffic, and one policy for the
inbound traffic.
To add the components of a One-to-One NAT policy, perform
the following steps:

For Translated Destination, select Create new address
object and create a new address object using WAN for
Zone Assignment and Host for Type.
For Original Service, select HTTP.
For Translated Service, select Original.
For Inbound Interface, select X0.
For Outbound Interface, select Any.
For Comment, enter a short description.
Select the Enable NAT Policy checkbox.
Select the Create a reflexive policy checkbox if you want
a matching NAT policy to be automatically created in the

Connecting the SonicPoint
Public Server on DMZ
When a SonicPoint unit is first connected and powered up, it
attempts to find a SonicOS device with which to peer. If it is
unable to find a peer SonicOS device, it will enter into a standalone mode of operation with a separate stand-alone
configuration allowing it to operate as a standard Access Point.
This section provides instructions for configuring your
SonicWALL TZ 210 series appliance to support a public Web
server on a DMZ zone.
If the SonicPoint locates a peer SonicOS device, such as your
SonicWALL TZ 210 series appliance, the two units perform an
encrypted exchange and the profile assigned to the relevant
wireless zone is used to automatically configure (provision) the
newly added SonicPoint unit.
To connect the SonicPoint:
1.
2.
3.
Using a CAT 5 Ethernet cable, connect the SonicPoint to
the interface that you configured. Then connect the
SonicPoint to a power source.
In the SonicOS user interface on the SonicPoint >
SonicPoints page, click the Synchronize SonicPoints
button. The SonicWALL appliance downloads a SonicPoint
image from the SonicWALL back-end server.
Follow the instructions in the SonicPoint wizard. Be sure to
select the same authentication type and enter the same
keys or password that you configured in SonicOS.
Note: For more information about wireless configuration, see
the SonicOS Enhanced Administrator’s Guide.
Page 40 Public Server on DMZ
A Web server can be placed on the LAN by completing the
server wizard, which creates the proper address objects and
rules for safe access.

About High Availability
Initial HA Setup
In this scenario, one SonicWALL TZ 210 series appliance
operates as the Primary gateway device and the other acts as
the Backup. Once configured for High Availability, the Backup
SonicWALL contains a real-time mirrored configuration of the
Primary SonicWALL via an Ethernet link between the
designated HA interfaces on each appliance.
Before you begin the configuration of HA on the Primary
SonicWALL security appliance, perform the following setup:
During normal operation, the Primary SonicWALL is in Active
mode and the Backup SonicWALL is in Idle mode. If the
Primary device loses connectivity, the Backup SonicWALL
transitions to Active mode and assumes the configuration and
role of the Primary gateway device. This automatic failover
ensures a reliable connection between the protected network
and the Internet.
2.
After a failover to the Backup appliance, all the pre-existing
network connections must be re-established, including the VPN
tunnels that must be re-negotiated.

7.
Page 46 Configuring High Availability
On the back panel of the Backup SonicWALL security
appliance, locate the serial number and write the number
down. You need to enter this number in the High
Availability > Settings page.
Verify that the Primary SonicWALL appliance is registered
and licensed for SonicOS Enhanced and the desired
SonicWALL security services.
Associate the two SonicWALL appliances as HA Primary
and HA Secondary on MySonicWALL, for license
synchronization.
Make sure the Primary SonicWALL and Backup
SonicWALL security appliances’ LAN, WAN and other
interfaces are properly configured for failover.
Connect the X6 ports on the Primary SonicWALL and
Backup SonicWALL appliances with a CAT 5 Ethernet
cable. The Primary and Backup SonicWALL security
appliances must have a dedicated connection.
Power up the Primary SonicWALL security appliance, and
then power up the Backup SonicWALL security appliance.
Do not make any configuration changes to the Primary’s
X6 interface; the High Availability configuration in an
upcoming step takes care of this issue.
TZ_210_GSG.book Page 47 Friday, November 14, 2008 10:29 AM
HA License Synchronization Overview
You can configure HA license synchronization by associating
two SonicWALL security appliances as HA Primary and HA
Secondary on MySonicWALL. Note that the Backup appliance
of your HA pair is referred to as the HA Secondary unit on
MySonicWALL.
You need only purchase a single license for SonicOS
Enhanced, a single Support subscription, and a single set of
security services licenses for the HA Primary appliance. These
licenses are shared with the HA Secondary appliance. Only
consulting services such as the SonicWALL GMS Preventive
Maintenance Service license are not shared. See Registering
Note: After registering new SonicWALL appliances on
MySonicWALL, you must also register each appliance
from the SonicOS management interface by clicking the
registration link on the System > Status page. This
allows each unit to synchronize with the SonicWALL
license server and share licenses with the associated
appliance.
and Licensing Your Appliance on MySonicWALL page 10.
License synchronization is used during HA so that the Backup
appliance can maintain the same level of network protection
provided before the failover. To enable HA, you can use the
SonicOS UI to configure your two appliances as a HA pair in
Active/Idle mode.
MySonicWALL provides several methods of associating the two
appliances. You can start by registering a new appliance, and
then choosing an already-registered unit to associate it with.
You can associate two units that are both already registered. Or
you can select a registered unit and then add a new appliance
with which to associate it.
