Feature Overview
What is SonicWALL PortShield Architecture
The SonicWALL PortShield feature enables you to configure some or all of the 24 LAN switch ports on
the SonicWALL PRO 1260 into separate contexts or PortShield interfaces, providing protection from
traffic on the WAN and DMZ, and devices inside your network. Each context has its own wire-speed
switch ports that have protection of a dedicated, deep packet inspection firewall.
You can assign any combination of ports on the SonicWALL PRO 1260 into a PortShield interface. By
default, all 25 ports are part of the primary LAN interface. All ports you do not assign to a PortShield
interface remain assigned to the LAN interface. For example, if you assign ports 4 through 12 to a
PortShield interface, ports 1 through 3, ports 13 through 24, and the Uplink port all remain assigned to
the LAN interface.
You can create standard SonicWALL address objects and assign them to a PortShield interface,
harnessing the convenience of using single objects to apply ranges or groups of non-consecutive
addresses to a PortShield interface. For ranges and hosts, you conveniently can create the address object
inside the PortShield interface creation environment.
You cannot assign Port 1 and the Uplink Port to a PortShield interface. They can only be part of a LAN
interface. The following figure shows a basic view of what three PortShield interfaces on one device
might look like.

Using PortShield Interfaces
Benefits
The benefits of PortShield interfaces are:
Increased Manageability
•
Provides a helpful organization mechanism that enables you to easily group ports into logical units
reserved for topically-related traffic.
•
Enables software configurations to be made uniform across devices by collapsing like resources into
a single subnetwork. As an example, using PortShield interfaces can reduce the number of
implementations of local server resources like DHCP.
Increased Performance
•
Provides improved traffic efficiency by enabling you to reserve port groups for more demanding
traffic and other port groups for less demanding traffic.
•
Provides improved traffic efficiency by enabling you to group users into logical networks by
limiting traffic to users performing similar functions, improving efficiency.
Increased Security
•
It enables you to block designated ports from accepting sensitive information, segmenting the ports
from more general traffic targeted for other ports which may be more prone to performance
degrading packet analysis, and filtering mechanisms.
•
It enables you to insulate designated ports from distressed segments experiencing flutter or that have
failed, reducing the potential for data loss, degraded data, and floods of error messages.
Platforms
The PortShield interface feature is available on the SonicWALL PRO 1260 running SonicOS Enhanced
version 3.1 or newer.
Supported Standards and RFCs
The SonicWALL PortShield interface technology feature supports the IEEE 802.1q standard, although
802.1q-based VLAN support is not available to the SonicWALL PRO 1260 as a user-controllable
function. 802.1q tags are used internally by the PortShield interface function to direct packets to the
correct interface after they enter the device.
The SonicWALL PortShield interface technology is based on the following RFCs, IEEE and other
standards documents:
•
ISO/IEC 15802-3
•
IEEE 802.1q VLAN Tagging draft

Prerequisites
Prerequisites for configuring a PortShield interface are:
•
You have a SonicWALL PRO 1260 running properly and all ports are in working order.
•
Port 1 and the Uplink port need to be enabled.
•
All other ports must meet two conditions: they must be enabled and have both the HTTP and HTTPS
management options enabled that allow a management session to be established between the
interface they map to and a network console.
When configuring a PortShield interface, you must configure the following elements:
•
Zone. You must configure a zone either as Trusted, Public, or Wireless zone types.
•
Name. You must assign a name to a PortShield interface.
•
Address Assignment Mode. The manner in which the interface receives its IP address.
•
IP Address/Subnet Mask. You must supply a unique IP address in non-overlapping subnetwork
space. Assignments to a trusted or public zone allow for either Transparent or Static addressing.
Assignments to a wireless zone continue to require a minimum of eight bits for host addressing.
Configuration Tasks
You can configure a PortShield interface in three ways.
•
Interfaces and Port Mappings in Two Sessions. You can configure a PortShield interface first
from the Interfaces environment and then by mapping ports to it in either of the two portions of the
SwitchPort environment:
– by selecting ports in the device graphic.
– by clicking on the pen and paper icon in the switch ports list in the Configure column.
By separating interface creation and switch port selection, you can focus more on each task. The
Switch Port environment provides a graphical representation of the SonicWALL PRO 1260
interfaces. This provides an easy way to visualize where ports reside and how intuitive it will be to
have certain ports grouped together into one PortShield interface. By having the interface already
configured in a previous session, you can focus more on how to set up your different domains.
•
Interfaces and Port Mappings in One Session. You can configure a PortShield interface and map
ports to it both in the Interfaces environment. This approach provides the advantage of being able
to quickly complete the configuration in one session in one environment. SonicOS provides an
easy-to-use, tabbed environment to perform both tasks in the same session.

Configuration Outlines
The following task outlines detail the different tasks involved in the three methods of PortShield
interface creation.
From the Interfaces Environment Only
To create a PortShield interface by configuring an interface and selecting ports to map to the interface
in the interface environment, you perform the following tasks:
1.
Establish a management session with the SonicWALL PRO 1260 device and access the Interfaces
environment.
2.
Create and add a PortShield interface to the list of interfaces. After you select a zone, you select a
series of ports that you want to assign to the PortShield interface. You then select a method of IP
address assignment.
3.
Complete the configuration of the interface settings.

Using PortShield Interfaces
From Both the Interfaces and Switch Ports Environments
To create a PortShield interface using the from both the interface and switch ports environments, you
perform the following tasks:
1.
Establish a management session with the SonicWALL PRO 1260 device and access the Interfaces
environment.
2.
Create and add a PortShield interface to the Interface list.
3.
Go to the Switch Port environment and assign ports to the PortShield interface you created.
4.
You can select ports for your PortShield interface in one of the following ways:
– from the device graphic.
– from the dialog box displayed by clicking on the pen and paper icon (the same dialog box
displayed in the Interface environment).
From the PortShield Interface Wizard
To create a PortShield interface using the PortShield wizard, you perform the following tasks:
1.
Establish a management session with the SonicWALL PRO 1260 device.
2.
From one of the environments listed here, launch the PortShield interface wizard. You can select the
PortShield interface wizard from one of the following environments:
– the System > Status page - the default environment (Wizards button located in the top-right
corner).
– the Network > Interfaces page (Wizards button located in the top-right corner)
– the Network > Switch Ports page (PortShield Wizard button located in the top-right corner)
– the Wizards page (PortShield Interface Wizard radio button displayed by clicking on the
Wizards option in the navigation pane)
3.
Navigate through the wizard screens, selecting and verifying one of the options presented for switch
partitioning, which divides the ports up into preset ranges and enables IP address assignment to the
interface.
Understanding IP Assignment Modes
You can use two different types of address assignment modes to create PortShield interfaces. They are
Static and Transparent. Each has benefits to it depending on the number of addresses you want to assign
to a PortShield interface. The following two sections describe each.
Working in Static Mode
When you create a PortShield interface in Static Mode, you manually create an explicit address to be
applied to the PortShield interface. All ports mapped to the interface are identified by this address. Static
mode is available on interfaces assigned to Trusted, Public, or Wireless zones. This approach is
appropriate if you are configuring only one address for a PortShield interface as it gives you more
control over the address selected while not taking a lot of time to manually make the assignment.
Configuring PortShield Interfaces
6
SonicOS Enhanced 3.1 Release
Using PortShield Interfaces
!
When you create a PortShield interface in Static Mode, verify the IP address you assign to the
interface is not already in use by another PortShield interface.
Note
Working in Transparent Mode
Transparent Mode addressing allows for the WAN subnetwork to be shared by the current interface using
Address Object assignments. The interface’s IP address is the same as the WAN interface IP address.
Transparent mode is available on interfaces assigned to Trusted and Public Zones.
!
Note
Verify the IP address you assign to the PortShield interface is within the WAN subnetwork.
When you create a PortShield interface in Transparent Mode, you create a range of addresses to be
applied to the PortShield interface. You include these addresses in one entity called an Address Object.
Address Objects allow for entities to be defined one time and to be re-used in multiple referential
instances throughout the SonicOS interface. When you create a PortShield interface using an address
object, all ports mapped to the interface are identified by any of the addresses specified in the address
range. This approach is appropriate when adding multiple addresses because it saves time and reduces
the potential for address conflicts.
Note
Each statically addressed PortShield interface must be on a unique subnetwork. You cannot overlap
PortShield interfaces across multiple subnetworks.
Creating a PortShield Interface from the Interfaces Area
Before creating and adding a PortShield interface, think about why you are creating it and what role it
will play in your network. To create and add a PortShield interface to the list of interfaces, perform the
following steps:
1.
Click on the Interfaces option. The management software displays the Interfaces Settings screen.
2.
Note the interfaces in the list contain the following columns of information:
Column
Description
Name
A string that identifies the interface.
Zone
The zone to which the interface maps.
IP Address
The IP address assigned to the interface.
Subnet Mask
The subnetwork mask value assigned to the IP address to indicate a range of
addresses.
IP Assignment
The method in which the interface obtains its IP address:
Static. Manually creating an explicit address to which you will map ports.
Transparent. Allows for the WAN subnetwork to be shared by the current interface
using Address Object assignments. The interface’s IP address will be the same as
the WAN interface IP address. Transparent mode is available on interfaces assigned
to Trusted and Public Zones.

SonicOS Administration Guide.
12. Click on the Create Default DHCP Lease Scope in the DHCP Server field to indicate that the amount
of time allowed for an IP address issued by DHCP will be the default.
Note
This option only appears when creating a PortShield interface, not when editing an existing
PortShield interface. You can make changes to the interface’s DHCP settings after creating an
interface from the DHCP Server environment (Network>DHCP Server).
13. Click on the Switch Ports tab. The management software displays the PortShield Interface Ports
dialog box.
14. In the Available Ports list, click on the port numbers you want to assign to the PortShield interface
and click on the right arrow (->) button to move them into the Assigned Ports list.
15. Click Ok. The management software adds the PortShield interface to the interface list.
Creating a New Zone for the PortShield Interface
You may want to create a zone for a PortShield interface that has different attributes to it than any of the
default zones provide. To create a new zone for a PortShield interface, perform the following:
1.
Click on the Zone list box and click on the Create new zone option. The management software
displays the General Settings dialog box.
2.
Type a string in the Name field that will identify the new zone.
3.
Click on the Security Type list box and click on a security type option that will classify the zone as
having a certain level of access. The choices are:
– Trusted. This security type offers the highest level of security, indicating that only trust,
indicating that the least amount of scrutiny is applied to traffic coming from trusted zones.
Trusted security can be thought of as being on the LAN (protected) side of the device. The LAN
zone is always Trusted.
– Public. This security type offers a higher level of security than an Untrusted zone, but a lower
level of trust than a Trusted zone. Public zones can be thought of as being a secure area between
the LAN (protected) side of the device and the WAN (unprotected) side. The DMZ, for example,
is a Public zone because traffic flows from it to both the LAN and the WAN.
– Wireless. This security type applies to the WLAN zone or any zone where the only interface to
the network consists of SonicWALL SonicPoint devices. You typical use WiFiSec to secure
traffic in a wireless zone.
4.
After selecting the security level for the PortShield interface, click on one of the checkboxes that
enables a security service for the zone. The following table details:

Click on the Link Speed list box and click on a transmission and receiving speed you want to assign
the interface. The choices are:
– Auto negotiate
– 100Mbps Full Duplex
– 100 Mbps Half Duplex
– 10 Mbps Full Duplex
– 10 Mbps Half Duplex
The link speed value indicates the transmission rate at which the device sends and receives packets
to and from a sending device. The duplex variable indicates whether the connection between the
SonicWALL PRO 1260 and the sending device allows concurrent transmissions from both devices.
Note
Do not change this setting from the default of Auto negotiate unless your system requires you to do
so. Also, note that for any setting involving the Full Duplex feature to work properly, be sure to
configure Full Duplex on both ends of the link. By not having Full Duplex configured on both ends,
a duplex mismatch occurs, causing throughput loss.
7.
Click on the Rate Limit option and click on a value. The rate limit value enables you to throttle
traffic coming into the switch. Remember, these values apply to inbound traffic only. The rate limit
choices are:
– 64 Kbps
– 128 Kbps
– 256 Kbps
– 512 Kbps
– 1 Mbps
– 4 Mbps
– 10 Mbps
– 20 Mbps

Using PortShield Interfaces
Mapping Ports from the Switch Ports Window
Another way to create a PortShield interface is to configure the interface in the Interfaces window and
then assign ports to it in the Switch Ports window. Approaching it this way assumes you created a
PortShield interface first and then selected the ports from the device ports graphic and selected the
existing interface. This provides several advantages:
•
enables you to easily visualize the actual locations of ports.
•
separating the task of creating the interface, helps you focus more on how you want to separate the
ports into different domains.
To select ports and apply them to a previously configured interface, perform the following steps:
1.
Either identify an existing PortShield interface that you want to map ports to or create a PortShield
interface following the steps in the section previously described, but do not map ports to it by going
into the Switch Ports tab.
2.
Click the Networks > Switch Ports option. SonicOS displays the Switch Ports window.
3.
Note the color of the ports. While you can map any port, no matter what its color, to an interface,
you should be aware of whether it has been selected for use in another PortShield interface. Ports in
different PortShield interfaces appear in different colors.
– From the device graphic, see if any of the ports you want to select appear in black or another
color. If a port is black, it is unused by another PortShield interface. If it is another color, it is
in use by a PortShield interface. Just be cognizant of ones that are being used and what impact
your remapping the port will have on the existing interface.
– From the Switch Ports list, see if any of the ports in the PortShield Interface list have been
selected as a PortShield interface.
Be cognizant of ones that are being used and what impact your remapping the port will have on the
existing interface.
4.
On the device graphic, click on ports 3, 4, 5, and 6. The selected ports appear as yellow.
5.
Click the Configure button. SonicOS displays the Switch Port Settings dialog box. Note the Name
field displays the ports you selected (P3, P4, P5, P6).
6.
Click on the PortShield Interface list box. Look for the PortShield interface name to which you want
to map ports.
7.
Click on the PortShield interface entry to which you want to map ports. By selecting this entry, you
mapped ports 3, 4, 5, and 6to it.
8.
Click Ok. View the Status: field at the lower left portion of the window. It displays the following
message:
Please wait
The device takes a few moments while it adds ports to the PortShield interface. When the process
completes, SonicOS displays the Switch Ports dialog box, displaying the results of your session.
When the device completes adding the ports, it displays the following message:

Using PortShield Interfaces
Creating Transparent Mode PortShield Interfaces
You may find it useful to create address objects to bundle addresses into address objects and reference
these objects when creating a PortShield interface. Address objects allow for entities to be defined one
time and to be reused in multiple referential instances throughout SonicOS. The PortShield interface
creation environment provides a convenient way to reference address objects.
The following example takes a network with a series of addresses in the range 67.115.118.80/24 and
divides it into three PortShield Interfaces, mapping each to the following ports and address objects:
PortShield Interface Port Numbers Mapped
Address Object Type

To create these PortShield interfaces, using the prescribed address objects, perform the following steps:
1.
Click on the Networks->Interfaces option. The management software displays the Interfaces
Settings screen.
2.
Click the Add PortShield Interface button. The management software displays the Add Port Shield

Note that the IP address is the actual subnetwork address, not the specific address you entered. In this
example, the address is 67.115.118.0 and not 67.115.118.90. This is because in Transparent mode,
the interface appears to users as having the same address as the gateway. Therefore your explicit
address is invisible or transparent to Internet users. It lets you keep assigned IP addresses in the WAN
subnet while protecting those hosts with full SonicWALL firewall protection (including services,
etc.).

Deployment Scenario
A SonicWALL PRO 1260 with PortShield can be used in a small hotel or apartment setting. For example,
an apartment complex with 20 apartments could have a PortShield group for each individual room, two
sonicpoints to give wireless access to residents, a small office LAN, and a mail and web server in a DMZ.
With all SonicWALL Security Services enabled, the network behaves as if each apartment had a separate
firewall.
!
Note
The easiest way to configure this example is to use the PortShield Wizard. Configure it to have 24
PortShield interfaces, with one port each. Then reconfigure the LAN to include 2 ports and
reconfigure the wireless group to include 2 ports. For more details on the PortShield Wizard, see the
appropriate wizard chapter.

•
Configure the SonicPoint Profile
•
Configure the Zones
•
Configure the PortShield Interfaces with the PortShield Wizard
•
Set Up the DMZ
Configure the SonicPoint Profile
This example uses two SonicPoints to grant wireless access to users throughout the complex. Residents
can log in with their accounts, and guest users can log in using Wireless Guest Services. The SonicPoint
profile contains the settings that the security appliance automatically applies to all connected
SonicPoints.
Follow the procedures in the Administration Guide and configure the SonicPoint profile. Keep the
defaults except where appropriate for your installation. Set the SSID for both 802.11a and 802.11g radios
to a name that identifies the apartment complex or hotel, for example, “SonicWALL Arms Resident
Internet.”
Configure the Zones
This example uses three zones inside its network, LAN, DMZ, and a custom zone, Residents. Residents
is a Wireless zone with SonicPoint Enforcement disabled, thus allowing both wireless and wired access.
Guest services is enabled, allowing both wired and wireless guest users access to the Internet.
Configure the three Zones used in this example. Follow the procedures in the Zones chapter in your
SonicOS Administration Guide.
LAN and DMZ: Leave the default configuration for these two zones.
Residents: Configure the Residents zone with the following values:

Small Business
One good example deployment for PortShield interface groups is a small business office, with 25 or
fewer clients on the network. PortShield allows the business to separate its network into contexts.
In this example, the network is divided into five zones, each served by a PortShield interface:
•
Administration (including Accounting and Payroll) is on the LAN zone.
•
General users in a custom Wireless zone. With SonicPoint Enforcement disabled, users in the
company can have both wired and wireless access to the network. Wireless Guest Services is
enabled to allow visitors to have both wired and wireless access to the Internet without access to the
corporate network.
•
Warehouse in a custom Wireless zone with SonicPoint Enforcement disabled. The warehouse has
two stationary computers and warehouse users also have wireless access for handheld devices.
•
The company has a DMZ for their mail server and Web server.
•
Catalog kiosks are set up in the main building for customers to use. They are in a separate Kiosk
zone.
All zones have the full array of SonicWALL Security Services enabled.

Glossary
•
802.1q - An IEEE standard developed to address the problem of how to break large networks into smaller
parts so broadcast and multicast traffic would not obtain more bandwidth than necessary. The standard
also helps provide a higher level of security between segments of internal networks. The 802.1q
specification establishes a standard method for inserting virtual LAN membership information into
Ethernet frames.
•
802.1q Tags - Virtual markers assigned to a physical port on the device that indicate which collision
domain or PortShield interface to which the port belongs.
•
Address Object - An aggregation mechanism that allows entities to be defined one time and to be
reused in multiple referential instances throughout SonicOS. PortShield interfaces enable you to
take advantage of the convenience of address objects by allowing you to map them either to a
previously created address object or to an object that you create during the PortShield interface
configuration session. You need to be in Transparent Mode to assign an address object to an
interface.
•
PortShield Interfaces - A software mechanism in SonicOS that enables you to configure some or
all of the 24 LAN switch ports on the SonicWALL PRO 1260 into separate contexts, providing
protection from traffic on the WAN and DMZ, and devices inside your network.
•
Primary LAN Interface - The default base entity to which all ports on the SonicWALL PRO 1260
belong, acting as the single, collective interface on the device. You can select allowable ports in the
Primary LAN to partition into separate PortShield interfaces that work separately but concurrently
with the Primary LAN interface. The Uplink port and Port 1 are not allowable ports to be included
in a newly created PortShield interface and always belong to the Primary LAN. By default, all
standard addressing and zone assignment defaults apply to the Primary LAN.
•
Rate Limiting - A limit that enables you to throttle traffic coming into the SonicWALL PRO 1260.
By specifying a throughput value in SonicOS, you make that value fastest throughput rate by which
incoming traffic can enter the device. This can be helpful in freeing an interface when it is
overloaded with traffic, enabling it to operate more efficiently.
•
Static Mode - A method of address assignment that allows you to explicitly assign a single address
to a PortShield interface.
•
Transparent Mode - A method of address assignment that allows for the WAN subnetwork to be
shared by the current interface using Address Objects. The interface’s IP address is the same as the
WAN interface IP address. Transparent mode is available on interfaces assigned to Trusted and
Public Zones.
