1 Secure Remote Access SonicWALL SRA Contents Platform Compatibility... 1 Known Issues... 1 Resolved Issues... 2 Deploying the SRA Virtual Appliance... 3 Related Technical Documentation Platform Compatibility The SonicWALL SRA release is supported on the following platforms: SRA 4200 SRA 1200 SRA Virtual Appliance When deploying the SonicWALL SRA Virtual Appliance, the elements of basic VMware structure must be implemented prior to deployment. The SonicWALL SRA Virtual Appliance is supported on the following VMware platforms: ESXi 4.0 Update 1 (Build and newer) ESX 4.0 Update 1 (Build and newer) Known Issues The following is a known issue in the SonicWALL SRA release: Symptom Condition / Workaround Issue DNS requests are not handled by the correct DNS server while NetExtender is connected, preventing consistent access to external sites and causing slow response times and inability to use certain applications. Occurs when NetExtender is used on a Mac running OS X 10.6.x. The SRA SSL-VPN appliance is configured to use one or two DNS servers, with corporate and ISP DNS servers also configured on the network. While NetExtender is running on the Mac, the remote DNS servers are not always used. This may be related to DNS resolution behavior changes in OS X 10.6.x meant to optimize DNS by allowing variable DNS server precedence

2 Resolved Issues The following issues are resolved in the SonicWALL SRA release: Symptom Condition / Workaround Issue Upgrading from the System > Settings page is not possible for the SRA Virtual Appliance. Virtual Appliance upgrade requires exporting and re-importing the SRA settings while deploying a new OVA template, and then resetting the license. NetExtender does not get installed on client systems when using the latest Firefox. NetExtender does not get installed on client systems when using the latest Chrome. An administrator using SonicWALL GMS to manage the SRA Virtual Appliance cannot login to the Virtual Appliance. SonicWALL GMS and ViewPoint do not generate reports about the SRA Virtual Appliance. Attempting to access a Citrix bookmark causes a blank window to pop up. Occurs when attempting to upgrade the SRA Virtual Appliance to a newer version. Occurs when using Firefox 4 to access the SRA Virtual Office portal and then clicking the NetExtender button. The browser requests the installation of an add-on, but after the user allows it, an error message is displayed. Occurs when using Chrome 10 to access the SRA Virtual Office portal and then clicking the NetExtender button. The NetExtender installation starts, but does not finish. Occurs because the SRA Virtual Appliance does not send its serial number to SonicWALL GMS or ViewPoint with its syslog messages or heartbeats. Occurs when using Internet Explorer with ActiveX to access a Citrix bookmark for XenApp6 and Citrix 4.5, while Cross Site Request Forgery (CSRF) protection is set to PREVENT. Workaround: Use Firefox, or select the IE option "Always use Java in Internet Explorer", then access the Citrix bookmark

The Open Virtualization Format (OVF) is a file format created by VMware and other leaders in the virtualization field that describes an open, secure, portable, efficient, and flexible format for the packaging and distribution of one or more virtual machines. VMware vsphere is VMware's first cloud operating system, able to manage large pools of virtualized computing infrastructure, including software and hardware. VMware vsphere 4 was originally developed as VMware Infrastructure (VI) 4, then became its own product called vsphere. VMware, Inc. is a leading provider of virtualization software. An Installation of VMware ESX or ESXi 4.0 is required to use the SonicWALL SRA Virtual Appliance. Introduction The SonicWALL SRA Virtual Appliance is a virtual machine that runs the SonicWALL SRA series software on a VMware platform. Deploying the SonicWALL SRA as a virtual appliance allows leveraging of shared computing resources to optimize utilization, easy migration and reduced capital costs. The SonicWALL SRA Virtual Appliance provides the following benefits: Cost savings: o Multiple virtual machines can run on a single server, reducing hardware costs, power consumption, and maintenance costs. o Microsoft Windows Server is not required, eliminating the cost of the Windows license. Operational ease: o In a virtual environment, it is easy to commission new servers or decommission old ones, or to bring servers up or down. o Installation is accomplished by importing a file into the virtual environment, with no need to run an installer. Security: o SonicWALL SRA Virtual Appliance provides the same hardened operating system that comes with the SonicWALL SRA 4200 appliance. 3

4 Installing the SonicWALL SRA Virtual Appliance The SonicWALL SRA Virtual Appliance is installed by deploying an OVA file to your ESX/ESXi server. Each OVA file contains all the necessary software components related to SonicWALL SRA software. You can deploy the OVA files multiple times as needed for your environment.

10 The name of the new SonicWALL SRA Virtual Appliance appears in the left pane of the vsphere window. Powering the Virtual Appliance On or Off There are multiple ways to power the SonicWALL SRA Virtual Appliance on or off. To power the virtual appliance on (or off), do one of the following: Right-click the SonicWALL SRA Virtual Appliance in the left pane and navigate to Power > Power On (or Power > Power Off) in the right-click menu. Select the SonicWALL SRA Virtual Appliance in the left pane and then click Power on the virtual machine (or Shut down the virtual machine) on the Getting Started tab in the right pane. Select the SonicWALL SRA Virtual Appliance in the left pane and then click Power On (or Shut down guest) on the Summary tab in the right pane. Configuring Interface IP and Route Settings on the Console After powering on the SonicWALL SRA Virtual Appliance, perform the following steps to open the console and configure the IP address and default route settings: 1. In vsphere, right-click the SonicWALL SRA Virtual Appliance in the left pane and select Open Console in the right-click menu. 10

11 2. When the console window opens, click inside the window, type admin at the sslvpn login: prompt and then press Enter. Your mouse pointer disappears when you click in the console window. To release it, press Ctrl+Alt. 3. Type password at the Password: prompt and then press Enter. The CLI prompt is displayed. 4. Configure the IP Address, Subnet, Gateway, and DNS with appropriate values for your network. 5. Refer to the Using the Command Line Interface section for information about changing the settings. Using the Command Line Interface The Command Line Interface (CLI) is a text-only mechanism for interacting with a computer operating system or software by typing commands to perform specific tasks. It is a critical part of the deployment of the SRA Virtual Appliance, where basic networking needs to be configured from the console. Note: The SonicWALL SRA 5.0 CLI allows configuration of only the X0 interface on the SonicWALL SRA 4200, SRA 1200, or SRA Virtual Appliance. While the SonicWALL SRA 1200 and 4200 physical appliance products have a default IP address and network configuration that requires a client s network settings to be reconfigured to connect, the network settings in the VMware virtual environment might conflict with the SonicWALL defaults. The CLI utility remedies this by allowing basic configuration of the network settings when deploying the SonicWALL SRA Virtual Appliance. After the Virtual Appliance firmware has fully booted, the following login prompt is displayed:,,,,,,,,,,,,,,,,,,mmbbbbbb bbbbbmm,,,,,,b PPPPPPP '''''''''''''''' PPPPPPPPP bbm,, '''''' '''''PPPP bm, '''PP bm, 'PP111111b, : Copyright (c) 2010 SonicWALL, Inc. SonicWALL SRA 4200 sslvpn login:.1111p.,b1pp ',, ''' To access the CLI, login as admin. The password is the same as the password for the admin account that is configured on the appliance. The default is password. sslvpn login: admin Password: <password> Note: User input used in the examples highlighted in red indicates text entered by the user. There is no coloring of text done on the real CLI. If the incorrect password is entered, the login prompt is displayed again. If the correct password is entered, the CLI is launched. Basic system information and network settings are displayed along with the main menu, as in the example below: System Information Model: SRA Virtual 4200 Serial Number: 0017C54172D4 Version: SonicOS SSL-VPN sv CPU (Utilization): l.8 GHz Via C7 Processor (2%) Total Memory: 2 GB RAM, 1 GB Flash System Time: 2010/09/21 13:39:51 Up Time: 0 Days 00:40:51 X0 IP Address: X0 Subnet mask: Default Gateway:

12 Primary DNS: Secondary DNS: n/a Hostname: sslvpn Main Menu 1. Setup Wizard 2. Reboot 3. Restart SSL-VPN Services 4. Logout Press <Ctrl-c> at any time to cancel changes and logout. Select a number (1-4): You can press Ctrl-C at any time to log out and exit the CLI, returning to the login prompt. The main menu has four selections: 1. Setup Wizard This option launches a simple wizard to change the basic network settings, starting with the X0 IP Address, X0 subnet mask, default gateway, primary and secondary DNS, and the hostname. The following CLI output illustrates an example where each field is changed: X0 IP Address (default ): X0 Subnet Mask (default ): Default Gateway (default ): Primary DNS: Secondary DNS (optional, enter "none" to disable): Hostname (default sslvpn): sra4200 New Network Settings: X0 IP Address: X0 Subnet mask: Default Gateway: Primary DNS: Secondary DNS: Hostname: sra4200 Would you like to save these changes (y/n)? If a field is not filled out, the prior value is retained, allowing you to change only a single field. After each field has been prompted, the new network settings are shown and a confirmation message is given for the user to review and verify the changes before applying them. The following shows the result when you save the changes: Would you like to save these changes (y/n)? y Saving changes...please wait... Changes saved! Press <Enter> to continue... After saving the changes, press Enter to return to the original display of the System Information and Network Settings and verify that the changes have taken effect: System Information Model: SRA 4200 Serial Number: 0017C54172D4 Version: SonicOS SSL-VPN sv CPU (Utilization): l.8 GHz Via C7 Processor (2%) Total Memory: 2 GB RAM, 1 GB Flash System Time: 2010/09/21 13:39:51 Up Time: 0 Days 00:40:51 X0 IP Address: X0 Subnet mask: Default Gateway: Primary DNS: Secondary DNS: Hostname: sra4200 Main Menu 1.

14 Configuring Settings on the Appliance Web Interface After configuring the IP address and default route settings on the SonicWALL SRA Virtual Appliance console, the next steps are to configure the rest of the appliance settings as you would for the SonicWALL SRA 4200 or SRA 1200 appliance. Perform the following steps to complete host configuration for the virtual appliance: 1. Launch a browser and enter the URL of the virtual appliance as configured in the steps above, such as: 2. On the appliance login page, type in the default credentials and then click Login to log in. The default credentials are: User: admin Password: password After login, you will see the familiar SRA management interface: 14

15 Licensing the SonicWALL SRA Virtual Appliance SonicWALL SRA provides for user based licensing. By default, the virtual appliance comes with a 5-user license. Extra licenses can be added in 5, 10, and 25 user denominations, up to a maximum that allows for 50 concurrent user sessions. Licensing is controlled by SonicWALL s license manager service, and customers can add licenses through their MySonicWALL accounts. Unregistered units support the default license allotment for their model, but the unit must be registered in order to activate additional licensing from MySonicWALL. License status is displayed in the SSL VPN management interface, on the Licenses & Registration section of the 'System > Status' page. If a user attempts to log in to the Virtual Office portal and there are no more available user licenses, the login page will display the error, No more User Licenses available. Please contact your administrator. The same error is displayed if a user launches the NetExtender client when all user licenses are in use. These login attempts are logged with a similar message in the log entries, displayed in the 'Log > View' page. To activate licensing for your virtual appliance, perform the following steps: 1. Login as admin, and navigate to the System > Licenses page. 2. Click the Activate, Upgrade or Renew services link. The MySonicWALL login page is displayed. 3. Type your MySonicWALL account credentials into the fields to login to MySonicWALL. This must be the account to which the virtual appliance is, or will be, registered. If the serial number is already registered through the MySonicWALL web interface, you will still need to login to get the license information updated on the virtual appliance itself. 4. Type the serial number of the virtual appliance into the Serial Number field. The serial number and authentication code are provided when the software is purchased. 5. Type the authentication code into the Authentication Code field. 6. Type a descriptive name for the virtual appliance into the Friendly Name field, and then click Submit. 7. Click Continue after the registration confirmation is displayed. 8. Optionally upgrade or activate licenses to other services displayed on the System > Licenses page. 9. After activation, view the System > Licenses page to see a cached version of the active licenses. 15

16 Important Differences between the SRA Virtual Appliance and SRA 4200/1200 All of the major features of the SonicWALL SRA 4200 and SRA 1200 appliances are supported, including the Virtual Office, NetExtender, Virtual Assist, Virtual Access, Application Offloading, and Web Application Firewall. Important differences are: System > Status The SRA Virtual Appliance by default does not have a serial number. The serial number must be imported. System > Settings The SRA Virtual Appliance does not have a ROM image or any of the SafeMode features found on the SRA 4200/1200. The System > Settings page therefore has no Firmware Management section. Currently, the SRA Virtual Appliance does not support any upgrade mechanism other than to deploy a new version of the SRA Virtual Appliance OVA file via vsphere. The export/import of settings paths works as expected, and the importing of settings from SRA 4200/1200 appliances into the SRA Virtual Appliance is supported. 16
