Platform Compatibility

The SonicOS 5.6.5.1 release is supported on the following SonicWALL security appliances:

SonicWALL NSA E8500

SonicWALL NSA E7500

SonicWALL NSA E6500

SonicWALL NSA E5500

SonicWALL NSA 5000

SonicWALL NSA 4500

SonicWALL NSA 3500

SonicWALL NSA 2400

SonicWALL NSA 240

SonicWALL TZ 210 / 210 Wireless-N

SonicWALL TZ 200 / 200 Wireless-N

This release supports the following Web browsers:

Internet Explorer 8.0 and higher

Chrome 4.0 and higher

Mozilla 3.0 and higher

Strong SSL and TLS Encryption Required in Your Browser

The internal SonicWALL Web server only supports SSL version 3.0 and TLS with strong ciphers (128 bits or

greater) when negotiating HTTPS management sessions. SSL implementations prior to version 3.0 and weak

ciphers (symmetric ciphers less than 128 bits) are not supported. This heightened level of HTTPS security protects

against potential SSLv2 roll-back vulnerabilities and ensures compliance with the Payment Card Industry (PCI) and

other security and risk-management standards.

TIP: By default, Mozilla Firefox 2.0 and Microsoft Internet Explorer 7.0 enable SSL 3.0 and TLS, and disable

SSL 2.0. SonicWALL recommends using the most recent Web browser releases. If you are using a previous

release of these browsers, you should enable SSL 3.0 and TLS and disable SSL 2.0. In Internet Explorer, go to

Tools > Internet Options on the Advanced tab and scroll to the bottom of the Settings menu. In Firefox, go to

Tools > Options on the Advanced tab, and then select the Encryption tab.

Link Aggregation Link Aggregation provides the ability to group multiple Ethernet interfaces to form a trunk

which looks and acts like a single physical interface. SonicOS 5.6.5.1 supports Static Link Aggregation, in which

the two ends of the trunk have the same configuration. Up to 4 ports can be grouped to form a single aggregate

link. If any of the ports fail, SonicOS continues to pass traffic (at a diminished throughput) while there is at least

one active interface.

Link Aggregation is useful in deployments requiring more than 1 Gbps throughput for traffic flowing between two

interfaces. This feature is available on all SonicWALL NSA E-Class appliances.

Link Aggregation is supported only on SonicWALL NSA E-Class appliances.

Port Redundancy Port Redundancy provides the ability to configure a second, redundant, physical interface

for any Ethernet interface on a SonicWALL NSA E-Class appliance. When the primary interface is active, it

handles all traffic to and from the interface. If the primary interface fails, the backup interface takes over and

handles all incoming and outgoing traffic. When the primary interface comes up again, it takes over all the traffic

handling duties from the backup interface.

This is very useful in high end deployments to avoid a single point of failure, such as the connection to a switch.

With Port Redundancy, a second interface can be connected to the same or another switch to provide an

alternate path for the traffic.

Port Redundancy is supported only on SonicWALL NSA E-Class appliances.

The following are the key features supported in all versions of SonicOS 5.6:

Deep Packet Inspection of SSL encrypted data (DPI-SSL) Provides the ability to transparently decrypt

HTTPS and other SSL-based traffic, scan it for threats using SonicWALL’s Deep Packet Inspection

technology, then re-encrypt (or optionally SSL-offload) the traffic and send it to its destination if no threats or

vulnerabilities are found. This feature works for both client and server deployments. It provides additional

security, application control, and data leakage prevention functionality for analyzing encrypted HTTPS and

other SSL-based traffic. The following security services and features are capable of utilizing DPI-SSL:

Gateway Anti-Virus, Gateway Anti-Spyware, Intrusion Prevention, Content Filtering, Application Firewall,

Packet Monitor and Packet Mirror. DPI-SSL is supported on SonicWALL NSA models 240 and higher.

3G and Modem Support SonicOS 5.6 supports 3G and Modem configurations for WAN Load Balancing

(WLB). (3G and Modem support is available on all NSA models except the SonicWALL NSA 2400.)

Command Line Interface Enhancements Provides increased support through the command line

interface to configure and modify Network Address Translation (NAT) Policies, Access Rules, Service

Objects, and Service Groups.

Diagnostic Improvements Includes a diagnostic tool which automatically checks the network

connectivity and service availability of several pre-defined functional areas of SonicOS. The tool also

returns results and attempts to describe causes, if any exceptions are detected.

Dynamic DNS per Interface Provides the ability to assign a Dynamic DNS (DDNS) profile to a specific

WAN interface. This allows administrators who are configuring WAN Load Balancing to advertise a

predictable IP address to the DDNS service.

Increased DPI Connection Support Provides the ability to increase the number of simultaneous

connections on which SonicWALL security appliances can apply Deep Packet Inspection (DPI) services

(Intrusion Prevention Service, Application Firewall, Gateway Anti-Virus, and Gateway Anti-Spyware). This

feature is intended for high-end (E-Class) customers who need to support a large number of concurrent

connections. (Note: There is a slight performance decrease when this option is enabled.)

FairNet for SonicPoint-N Provides the ability to create policies that equally distribute bandwidth for all

wireless users connected to a SonicPoint-N.

MAC-IP Spoof Detection and Prevention Provides additional protection against MAC address and IP

address based spoofing attacks (such as Man-in-the-Middle attacks) through configurable Layer 2 and

Layer 3 admission control.

Packet Mirroring Provides the ability to capture copies of specified network packets from other ports.

This is commonly used for network appliances that require monitoring of network traffic, such as an

intrusion detection system. Customers can now gather data from one of the other ports on a SonicWALL to

look for threats and vulnerabilities and help aid with diagnostics and troubleshooting.

Route-based VPN with Dynamic Routing Support Extends support for advanced routing (either OSPF

or RIP) to VPN networks. This simplifies complex VPN deployments by enabling dynamic routing to

determine the best path that traffic should take over a VPN tunnel.

Signature Download through a Proxy Server Provides the ability for SonicWALL security appliances to

download signatures even when they access the Internet through a proxy server. This feature also allows

for registration of SonicWALL security appliances through a proxy server without compromising privacy.

Single Sign-on for Terminal Services and Citrix Provides support for transparent authentication of

users logged in from a Terminal Services or Citrix server. This transparent authentication enables

Application Firewall and CFS policy enforcement in Terminal Services and Citrix environments.

NOTE: The SonicWALL Terminal Services Agent is not supported in SonicOS 5.6.5.1 due to limitations of

current SSO agent functionality that prevent its use with Active/Active Clustering.

SSL VPN Enhancements SonicOS 5.6 provides a number of SSL VPN enhancements:

Bookmarks for SSH and RDP Provides support for users to create bookmarks on the SSL VPN

Virtual Office to access systems using SSH, RDP, VNC, and Telnet services.

Granular User Controls Allows network administrators to configure different levels of policy

access for NetExtender users based on user ID.

One-Time Password Provides additional security by requiring users to enter a randomly

generated, single-use password in addition to the standard user name and password credentials.

Separate Port and Certificate Control Provides separate port access for SSL VPN and HTTPS

management certificate control, allowing administrators to close HTTPS management while leaving

SSL VPN open.

Virtual Assist Provides a remote assistance tool to SonicWALL security appliance users.

SonicWALL Virtual Assist is a thin client remote support tool provisioned via a Web browser. It

enables a technician to assume control of a customer’s PC or laptop for the purpose of providing

remote technical assistance.

Unbounded Multiple WAN Support Provides the ability to enable any number of WAN Ethernet

interfaces for WAN Load Balancing and Failover on SonicWALL appliances.

VPN Policy Bound to VLAN Interface Allows users to bind a VPN policy to a VLAN interface when

configuring a site-to-site VPN.

WebCFS Server Failover Provides the ability to enable WebCFS server failover, allowing a SonicWALL

security appliance to contact another server for URL rating information if the local server is unavailable. This

ensures performance continuity for Web navigation and Web content filtering functionality.

Known Issues

This section contains a list of known issues in the SonicOS 5.6.5.1 release.

Symptom

Condition / Workaround

Issue

In Active/Active clustering, a node cannot

access MySonicWALL for license

Occurs when the node does not own a Virtual Group,

which can occur when it is configured with factory

Default Gateway and DNS server fail.

when the license is activated, but the unit is not yet

configured to own a Virtual Group. Workaround:

Before connecting the node to the A/A Cluster, register

the units and synchronize with MySonicWALL.

The redundant port for the X1 WAN

interface does not pass traffic after X1 is

disconnected.

Occurs when High Availability is enabled for

Active/Passive mode, and X4 or another interface is

configured as a redundant port for X1, and then the X1

interface is physically disconnected. Workaround:

Disable High Availability and then traffic is passed on

the redundant port.

97883

The gateway IP address is wrong for

default routes received from OSPF.

Occurs when a remote router or firewall is connected to 97409

a SonicWALL appliance (X1 on router is connected to

a DMZ zone port (X2) on the appliance). OSPF is

enabled on both devices, the router advertises a

default route to the appliance, and the appliance adds

the default route to its routing table. However, the

gateway IP address for the default route is set to the IP

address of the router’s X1 interface, rather than to the

router’s gateway IP address.

In Active/Active clustering, the IP address

for interface X1, Virtual Group 2 reverts to

the IP address for X1, Virtual Group 1.

Occurs when verifying NAT policies after running the

Public Server Wizard. The IP address for X1-Virtual

Group 2 incorrectly displays the address for X1-Virtual

Group 1 instead.

unit in Node 2, although traffic continues to

pass and the active unit shows the tunnel.

When Active/Active clustering is enabled,

settings for the Packet Monitor filter are

copied to the Display filter. The Display

filter settings cannot be removed.

Occurs when the Packet Monitor filter settings are

added before enabling Active/Active clustering. The

Display filter contains these settings even after

manually clearing them and then restarting the

SonicWALL appliance.

93188

90256

When using Active/Active Clustering with

four nodes where each node is part of HA

pair, traffic from the HA idle units cannot

go out and they cannot connect to the

License manager.

Occurs on Active/Active clusters with four nodes

configured as HA pairs. Multiple WAN interfaces are

configured and probing/probe target is enabled. When

one of the WAN interfaces is down, the default route of

the idle units remain pointed to the down WAN

interface.

Symptom

Condition / Workaround

Issue

Traffic over static VPN routes is dropped

after a node level link failover.

Occurs after the X1 link on the Master node is

disconnected. Traffic will drop over the VPN tunnel,

but after flushing the connection, traffic will

recommence flowing through the tunnel.

should show as “BGP route.”

When a node is deleted from the

Active/Active Nodes table on the High

Availability page, the interface is not

deleted from the Network > Interfaces

page.

Occurs when deleting a node from the Active/Active

Nodes table and then viewing the Network > Interfaces

page. Workaround: Click the edit icon for the deleted

interface and then click OK. The interface will be

deleted.

89017

OSPF continues to advertise the Default

Route even after a WAN link failure due to

WAN Load Balancing logical probing.

Occurs when the option is enabled to advertise the

default route when the WAN is up, and WLB Probing is

enabled on the WAN. Upon a WAN link failure, OSPF

will still display the default route.

88371

68413

Incorrectly configured routes prevent the

user from connecting to or pinging the

directly connected network.

Occurs when a preferences file is uploaded containing

custom routes in which the Destination network is

pointing to a LAN subnet and the Default Gateway is in

the same subnet, or the Destination firewall interface IP

address is routed to the Default Gateway IP address.

Importing Preferences from SonicOS Standard to SonicOS 5.6 Enhanced

The SonicOS Standard to Enhanced Settings Converter is designed to convert a source Standard Network Settings

file to be compatible with a target SonicOS Enhanced appliance. Due to the more advanced nature of SonicOS

Enhanced, its Network Settings file is more complex than the one SonicOS Standard uses. They are not

compatible. The Settings Converter creates an entirely new target Enhanced Network Settings file based on the

network settings found in the source Standard file. This allows for a rapid upgrade from a Standard deployment to

an Enhanced one with no time wasted in re-creating network policies. Note: SonicWALL recommends deploying the

converted target Network Settings file in a testing environment first and always keeping a backup copy of the

original source Network Settings file.

The SonicOS Standard to Enhanced Settings Converter is available at:

https://convert.global.sonicwall.com/

If the preferences conversion fails, email your SonicOS Standard configuration file to

[email protected] with a short description of the problem. In this case, you may also consider

manually configuring your SonicWALL appliance.

To convert a Standard Network Settings file to an Enhanced one:

1. Log in to the management interface of your SonicOS Standard appliance, navigate to System > Settings,

and save your network settings to a file on your management computer.

2. On the management computer, point your browser to https://convert.global.sonicwall.com/.

3. Click the Settings Converter button.

4. Log in using your MySonicWALL credentials and agree to the security statement.

The source Standard Network Setting file must be uploaded to MySonicWALL as part of the conversion

process. The Setting Conversion tool uses MySonicWALL authentication to secure private network settings.

Users should be aware that SonicWALL will retain a copy of their network settings after the conversion

process is complete.

5. Upload the source Standard Network Settings file:

Click Browse.

Navigate to and select the source SonicOS Standard Settings file.

Click Upload.

Click the right arrow to proceed.

6. Review the source SonicOS Standard Settings Summary page.

This page displays useful network settings information contained in the uploaded source Network Settings

file. For testing purposes, the LAN IP and subnet mask of the appliance can be changed on this page in

order to deploy it in a testing environment.

(Optional) Change the LAN IP address and subnet mask of the source appliance to that of the

target appliance.

Click the right arrow to proceed.

7. Select the target SonicWALL appliance for the Enhanced deployment from the available list.

SonicOS Enhanced is configured differently on various SonicWALL appliances, mostly to support different

interface numbers. As such, the converted Enhanced Network Settings file must be customized to the

appliance targeted for deployment.

8. Complete the conversion by clicking the right arrow to proceed.

9. Optionally click the Warnings link to view any differences in the settings created for the target appliance.

10. Click the Download button, select Save to Disk, and click OK to save the new target SonicOS Enhanced

Network Settings file to your management computer.

11. Log in to the management interface for your SonicWALL appliance.

12. Navigate to System > Settings, and click the Import Settings button to import the converted settings to

your appliance.

Using SafeMode to Upgrade Firmware

The SafeMode procedure uses a reset button in a small pinhole, whose location varies: on the NSA models, the

button is near the USB ports on the front; on the TZ models, the button is next to the power cord on the back. If you

are unable to connect to the SonicWALL security appliance’s management interface, you can restart the

SonicWALL security appliance in SafeMode. The SafeMode feature allows you to quickly recover from uncertain

configuration states with a simplified management interface that includes the same settings available on the

System > Settings page.

To use SafeMode to upgrade firmware on the SonicWALL security appliance, perform the following steps:

1. Connect your computer to the X0 port on the SonicWALL appliance and configure your IP address with an

address on the 192.168.168.0/24 subnet, such as 192.168.168.20.

2. Do one of the following to restart the appliance in SafeMode:

Use a narrow, straight object, like a straightened paper clip or a toothpick, to press and hold the reset

button on the front of the security appliance for more than 20 seconds.

Use the LCD control buttons on the front bezel to set the appliance to Safe Mode. Once selected, the

LCD displays a confirmation prompt. Select Y and press the Right button to confirm. The SonicWALL

security appliance changes to SafeMode.

The Test light starts blinking when the SonicWALL security appliance has rebooted into SafeMode.

Note: Holding the reset button for two seconds will send a diagnostic snapshot to the console. Holding the

reset button for six to eight seconds will reboot the appliance in regular mode.

3. Point the Web browser on your computer to 192.168.168.168. The SafeMode management interface

displays.

4. If you have made any configuration changes to the security appliance, select the Create Backup On Next

Boot checkbox to make a backup copy of your current settings. Your settings will be saved when the

appliance restarts.

5. Click Upload New Firmware, and then browse to the location where you saved the SonicOS firmware

image, select the file, and click Upload.

6. Select the boot icon in the row for one of the following:

Uploaded Firmware – New!

Use this option to restart the appliance with your current configuration settings.

Uploaded Firmware with Factory Defaults – New!

Use this option to restart the appliance with default configuration settings.

7. In the confirmation dialog box, click OK to proceed.

8. After successfully booting the firmware, the login screen is displayed. If you booted with factory default

settings, enter the default user name and password (admin / password) to access the SonicWALL

management interface.
