SonicOS 5.9 Upgrade Guide

SonicWall™ SonicOS 5.9

Upgrade Guide
April 2017

This Upgrade Guide provides instructions for upgrading your SonicWall™ network security appliance to SonicOS 5.9 from a previous release.

 
* 
NOTE: On SonicWall TZ series and some smaller NSA series platforms such as the NSA 220, performance may be affected after upgrading to SonicOS 5.9.1.8. This is due to the large number of features, enhancements, and vulnerability fixes provided in SonicOS 5.9, as compared to the SonicOS 5.8 releases. These features and updates are essential to better secure your network.

This guide also provides information about importing the configuration settings from an appliance running SonicOS 5.8 or 5.9 to a different appliance. See Importing Configuration Settings for details about the platforms and firmware versions supported.

Topics:

Obtaining the Latest SonicOS Firmware

To obtain a new SonicOS firmware image file for your SonicWall security appliance:
1
In a browser on your management computer, log into your MySonicWALL account at https://www.mysonicwall.com/.
2
In MySonicWALL, click Downloads in the left navigation pane to display the Download Center screen.
3
Select your product in the Software Type drop-down list to display available firmware versions.
4
To download the firmware to your computer, click the link for the firmware version you want. You can also download the Release Notes and other associated files in the same way.

Creating a System Backup and Exporting Your Settings

Topics:

Creating a System Backup

Before beginning the update process, you can use the Create Backup button to make a system backup on your SonicWall appliance.

On SonicWall NSA 2400 and above, and on E-Class NSA appliances, the backup feature saves a copy of the current system state, firmware, and configuration settings on your appliance, protecting all your existing settings if you need to return to a previous configuration.

 
* 
NOTE: The TZ series, SOHO, NSA 220 series, NSA 240, and NSA 250M series do not support a full firmware image backup.

Creating Backup Settings

On SonicWall TZ series (except TZ 100 and TZ 200 series), SOHO, NSA 220 series, NSA 240, and NSA 250M series, you can use the Create Backup Settings button to save a copy of the configuration settings locally on the firewall. The saved settings can be used with the current firmware version or with a newly uploaded firmware version.

 
* 
NOTE: The TZ 100 series and TZ 200 series do not support saving a copy of the settings directly on the unit.

Exporting Settings

On all appliance platforms, you can export the appliance configuration settings to a file on your local management station. This file serves as an external backup of the configuration settings, and can be imported into another appliance or into the same appliance if it is necessary to reboot the firmware with factory default settings.

To save a system backup on your appliance and export configuration settings to a file on your local management station:
1
To save a system backup or backup settings in the System > Settings page, do one of the following:
On an NSA 2400 or above, click Create Backup. SonicOS takes a snapshot of your current system state, firmware, and configuration preferences, and makes it the new System Backup firmware image. Clicking Create Backup overwrites the existing System Backup image, if any. The System Backup entry is displayed in the Firmware Management table.
On a TZ series, SOHO, NSA 220 series, NSA 240, or NSA 250M series, click Create Backup Settings. SonicOS saves a small file on the appliance with all your configuration settings. Any previous backup settings file is overwritten. The Firmware Management table displays the Current Firmware with Backup Settings entry.
 
* 
NOTE: A Download button is displayed in the Firmware Management table for System Backup. However, the downloaded file cannot be imported into an appliance, nor can it be uploaded like firmware. Use Export Settings to save your configuration settings for import into another appliance.
2
To export your settings to a local file, click Export Settings.
3
Click Export in the popup window that displays the name of the saved file.

Upgrading Firmware with Current Settings

You can update the SonicOS image on a SonicWall security appliance by connecting your computer to the LAN (X0) port or you can update it remotely if the LAN or WAN interface is configured for remote management access.

To upload new firmware to your SonicWall appliance and use your current configuration settings upon startup:
1
Download the SonicOS firmware image file from MySonicWall and save it to a location on your local computer.
2
Point your browser to the appliance IP address, and log in as an administrator.
3
On the System > Settings page, click Upload New Firmware.
4
Navigate to the location where you saved the SonicOS firmware image file, select the file, and click Upload. After the firmware finishes uploading, it is displayed in the Firmware Management table.
5
On the System > Settings page, click the Boot icon in the row for Uploaded Firmware – New!
6
In the confirmation dialog box, click OK. The appliance restarts and displays the login page.
7
Enter your user name and password. Your new SonicOS image version information is displayed on the System > Status page.

Upgrading Firmware with Factory Default Settings

To upload new firmware to your SonicWall appliance and start it up using the default configuration:
1
Download the SonicOS firmware image file from MySonicWall and save it to a location on your local computer.
2
Point your browser to the appliance IP address, and log in as an administrator.
3
Navigate to the System > Settings page and click Upload New Firmware.
4
Navigate to the location where you saved the SonicOS firmware image file, select the file, and click Upload.
5
On the System > Settings page, click the Boot icon in the row for Uploaded Firmware with Factory Default Settings – New!
6
In the confirmation dialog box, click OK. The appliance restarts and then displays the options to launch the Setup Wizard or go to the login page of the SonicOS management interface.
 
* 
NOTE: The IP address for the X0 (LAN) interface reverts to the default, 192.168.168.168. You can log into SonicOS by connecting to X0 and pointing your browser to https://192.168.168.168/.
7
Enter the default user name and password (admin/password) to access the SonicOS management interface.

Upgrading Caveats for VPN Tunnel Interfaces

VPN tunnel interfaces created in SonicOS 5.8 are missing on some platforms after upgrading to SonicOS 5.9. This includes tunnel interfaces with or without advanced routing (OSPF and RIP) enabled.

An unnumbered tunnel interface does not have an IP address and can be used as an egress interface when defining a static route. If enabled for advanced routing, it must borrow an IP address from either a physical or logical (VLAN) interface. A numbered tunnel interface has an IP address specifically assigned to it.

On platforms supporting unnumbered tunnel interfaces in SonicOS 5.9, all VPN tunnel interfaces continue to function normally after upgrading.

However, the upgrading process does not automatically convert unnumbered tunnel interfaces in SonicOS 5.8 to numbered tunnel interface configurations in SonicOS 5.9.

 
* 
NOTE: To work around this issue, manually reconfigure VPN tunnel interfaces and routing settings after upgrading to SonicOS 5.9.

When using advanced routing in SonicOS 5.8, borrowed interfaces do not have to be in the same subnet on both ends of the VPN tunnel. However, it is a best practice to do so. When using numbered tunnel interfaces for advanced routing in SonicOS 5.9, the subnet must be the same on both ends of the VPN tunnel. Be sure to consider this when reconfiguring tunnel interfaces after upgrading to SonicOS 5.9.

Numbered and unnumbered tunnel interface implementations are mutually exclusive in SonicOS 5.9, so if numbered tunnel interfaces are supported on a device, unnumbered tunnel interfaces are not supported on that device and vice versa.

 

Tunnel Interface Support per Platform in SonicOS 5.9

Numbered Tunnel Interface supported, No Conversion from Unnumbered Tunnel Interfaces

Unnumbered Tunnel Interfaces Supported, Advanced Routing Supported

Unnumbered Tunnel Interfaces Supported, Advanced Routing Not Supported

NSA 240

 

 

NSA 220/220W

 

 

TZ 215/215W

 

 

 
* 
NOTE: When advanced routing is configured and OSPF is enabled on an unnumbered tunnel interface, the tunnel interface maximum transmission unit (MTU) in SonicOS 5.8 is different from the MTU in SonicOS 5.9:
SonicOS 5.8 – MTU is 1500
SonicOS 5.9 – MTU is 1446

If you have this type of tunnel between one appliance running 5.8 and another running 5.9, the OSPF tunnel interface MTU must be adjusted or set to be ignored.

Using SafeMode to Upgrade Firmware

If you are unable to connect to the SonicOS 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.

The SafeMode procedure uses a recessed reset button in a small pinhole:

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 connection on the back.
To use SafeMode to upgrade firmware on a SonicWall security appliance:
1
Connect your computer to the X0 port on the appliance and configure your computer with an IP 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 security appliance for more than 20 seconds.
On platforms with an LCD screen and control buttons on the front bezel, you can use the LCD control buttons to set the appliance to SafeMode. 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 appliance has rebooted into SafeMode.

 
* 
NOTE: Holding the reset button for two seconds sends a diagnostic snapshot to the console. Holding the reset button for six to eight seconds reboots the appliance in regular mode.
3
Point the browser on your computer to 192.168.168.168. The SafeMode management interface displays.
4
Click Upload New Firmware.
5
Navigate to where you saved the SonicOS firmware image, select the file, and click Upload.
6
Click 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 Default Settings – New!

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

7
In the confirmation dialog box, click OK to proceed.
8
If you booted with current configuration settings, reconfigure your computer as needed to automatically obtain an IP address and DNS server address, or reset it to its normal static values.
9
Connect the computer to your network or leave it connected to the X0 (LAN) interface of the appliance, and point your browser to the WAN or LAN (depending on how you are connected) IP address of the SonicWall appliance.
10
If you booted with factory default settings, enter the default user name and password (admin / password) to access the SonicOS management interface. The default IP address of the X0 interface is 192.168.168.168.

Importing Configuration Settings

You can import configuration settings from one appliance to another, which can save time when replacing an older appliance with a newer model. This feature is also useful when you need multiple appliances with similar configuration settings.

Importing configuration settings, or preferences (also called prefs), to SonicWall network security appliances running SonicOS 5.9 is generally supported from the following SonicWall appliances:

NSA E-Class Series
NSA Series
TZ 215/210/205/105 Series
TZ 200/100/190/180/170 Series
PRO Series

Preferences cannot be imported in the following situations:

Settings files containing Portshield interfaces created prior to SonicOS 5.0
Settings files containing VLAN interfaces are not accepted by the TZ 100/200 Series firewalls
Settings files from a PRO 5060 with optical fiber interfaces where VLAN interfaces have been created
To export the configuration settings from an appliance:
1
Navigate to the System > Settings page in SonicOS.
2
Click the Export Settings button.
3
Import the settings file to another appliance by clicking the Import Settings button on that page.

Refer to the related topics and import matrices in the following sections:

Importing Settings from SonicOS Standard to SonicOS 5.9 Enhanced

The SonicOS Standard to Enhanced Settings Converter is designed to convert a source Standard Network Settings file to be compatible with a target appliance running SonicOS Enhanced, such as SonicOS 5.9. 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 settings_converter@sonicwall.com 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.
2
Navigate to System > Settings.
3
Export your network settings to a file on your management computer.
4
On the management computer, point your browser to https://convert.global.sonicwall.com/.
5
Click the Settings Converter button.
6
Log in using your MySonicWall credentials and agree to the security statement.
7
Upload the source Standard Network Setting file 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.
8
Upload the source Standard Network Settings file:
a
Click Browse.
b
Navigate to and select the source SonicOS Standard Settings file.
c
Click Upload.
d
Click the right arrow to proceed.
9
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 to deploy it in a testing environment.

a
(Optional) Change the LAN IP address and subnet mask of the source appliance to that of the target appliance.
b
Click the right arrow to proceed.
10
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.

11
Complete the conversion by clicking the right arrow to proceed.
12
Optionally click the Warnings link to view any differences in the settings created for the target appliance.
13
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.
