Virtual Office Overview

This chapter provides an overview of the SonicWALL SSL VPN user portal. It also includes an introduction to the SSL-VPN and its features and applications. This chapter contains the following sections:
“Virtual Office Overview” section on page 9
“Browser Requirements” section on page 10
“Web Management Interface Overview” section on page 12

Virtual Office Overview

SonicWALL SSL VPN Virtual Of fice provides secure remote access to network resources, such as applications, files, intranet Web sites, and email through Web access interface such as Microsoft Outlook Web Access (OWA). The underlying protocol used for these sessions is SSL.
With SSL VPN, mobile workers, telecommuters, partners, and customers can access information and applications on your intranet or extranet. What information should be accessible to the user is determined by access policies configured by the SonicWALL SSL VPN administrator.

Accessing Virtual Office Resources

Remote network resources can be accessed in the following ways:
Using a standard Web browser - To access network resources, you must log into the SSL
VPN portal. Once authenticated, you may access intranet HTTP and HTTPS sites, offloaded portals, Web-based applications, and Web-based email. In addition, you may upload and download files using FTP or Windows Network File Sharing. All access is performed through a standard Web browser and does not require any client applications to be downloaded to remote users’ machines.
Using Java thin-client access to corporate desktops and applications – The
SonicWALL SSL-VPN security appliance includes several Java or ActiveX thin-client programs that can be launched from within the SonicWALL SSL-VPN security appliance. Terminal Services and VNC Java clients allow remote users to access corporate servers and desktops, open files, edit and store data as if they were at the office. Terminal Services provides the ability to open individual applications and support remote sound and print services. In addition, users may access Telnet and SSH servers for SSH version 1 (SSHv1) and SSH version 2 (SSHv2), from the SSL VPN portal.

Browser Requirements

Using the NetExtender SSL VPN client – The SonicWALL SSL VPN network extension
client, NetExtender, is available through the SSL VPN Virtual Office portal via an ActiveX control or through stand-alone applications for Windows, Linux, MacOS, Windows Mobile, and Android smartphone platforms. To connect using the SSL VPN client, log into the portal, download the installer application and then launch the NetExtender connector to establish the SSL VPN tunnel. The NetExtender Android client has a different installation process, described in this guide. Once you have set up the SSL VPN tunnel, you can access network resources as if you were on the local network.
The NetExtender standalone applications are automatically installed on a client system the first time you click on the NetExtender link in the Virtual Of fice portal. The st andalone client can be launched directly from users’ computers without requiring them to log in to the SSL VPN portal first.
For SSL VPN to work as described in this guide, the SonicWALL SSL-VPN security appliance must be installed and configured according to the directions provided in the SonicWALL SSL- VPN Getting Started Guide for your model.
Browser Requirements
The following Web browsers are supported for the SSL VPN Virtual Office portal:
Internet Explorer 7.0+, 8.0+
Firefox 3.0+
Safari 5.0+

The administrator may also define bookmarks, or preconfigured links, to Web sites or computers on the intranet. Additional bookmarks may be defined by the end user.
SonicWALL NetExtender is a software application that enables remote users to securely connect to the remote network. With NetExtender, remote users can virtually join the remote network. Users can mount network drives, upload and download files, and access resources in the same way as if they were on the local network.
If the SSL-VPN appliance uses a self-signed SSL certificate for HTTPS authentication, then it is recommended to install the certificate before establishing a NetExtender connection. If you are unsure whether the certificate is self-signed or generated by a trusted root Certificate Authority, SonicWALL recommends that you import the certificate. The easiest way to import the certificate is to click the Import Certificate button at the bottom of the Virtual Office home page.

Verifying User One-Time Password Configuration

If you are successfully logged in to Virtual Office, you have correctly used the One-Time Password feature.
If you cannot login using the One-Time Password feature, verify the following:
Are you able to login to the Virtual Office without being prompted to check your email for a
one-time password? You have not been enabled to use the One-Time Password feature. Contact your SSL VPN administrator.
Is your email address correct? If your email address has been entered incorrectly, contact
your SSL VPN administrator to correct it.
Is there no email with a one-time password? Wait a few minutes and refresh your email
inbox. Check your spam filter. If there is no email after several minutes, try to login again to generate a new one-time password.
Have you accurately typed the one-time password in the correct field? Re-type or copy and
paste the one-time password.

Troubleshooting Common Errors

Using NetExtender

Symptom I see an error message indicating that an email configuration is invalid, and I have
verified that the One-Time Password feature is configured correctly.
Possible Cause The SonicWALL SSL VPN One-Time Password feature does not support
email servers that require passwords or other authentication. Your email server must allow anonymous access to allow the One-Time Password feature to successfully send a one-time password.

The easiest way to import the certificate is to click the Import Certificate button at the bottom of the Virtual Office home page.
Prerequisites for Windows Mobile Clients
NetExtender supports the following Windows Mobile platforms:
Windows Mobile 5 PocketPC version
Windows Mobile 6 Professional/Classic version
Windows Mobile 5 Smart Phone version and Windows Mobile 6 Standard version are not currently supported.
Prerequisites for MacOS Clients:
MacOS clients meet the following prerequisites in order to use NetExtender:
MacOS 10.5 and higher
Java 1.5 and higher
Both PowerPC and Intel Macs are supported.
Prerequisites for Linux Clients:
Linux 32-bit or 64-bit clients are supported for NetExtender when running one of the following distributions (32-bit or 64-bit):
Linux Fedora Core 8 or higher, Ubuntu 7 or higher, or OpenSUSE 10.3 or higher
Sun Java 1.4 and higher is required for using the NetExtender GUI.

SonicWALL SSL VPN 5.0 User Guide
Page 25
Using NetExtender
As new features are added, users must install the updated client to access all the features supported by the new firmware. Likewise, if a new client is used with older firmware, some client features may not be functional. For best results, the latest firmware should always be used with the latest client.
Note Only rooted devices are supported for NetExtender Android in SonicWALL SSL VPN 5.0.
The rooting requirement is due to limitations and restrictions of the Android platform. A layer 3 VPN client like NetExtender requires root permission for certain necessary OS level operations. Until a future version of the Android OS provides a flexible API to do these operations without root access, the rooting requirement will remain.
Warning
Rooting your phone may void your warranty. Consult your contract or User’s Guide, or call your service provider for more information.

Using Virtual Assist

Virtual Assist is an easy to use tool that allows SonicWALL SSL VPN users to remotely support customers by taking control of their computers while the customer observes. Virtual Assist is a lightweight, thin client that installs automatically using Java from the SonicWALL SSL VPN Virtual Office without requiring the installation of any external software. For computers that do not support Java, Virtual Assist can be manually installed by downloading an executable file from the Virtual Office.
The following sections describe how to use Virtual Assist:
“Understanding Virtual Assist” section on page 77
“Installing and Launching Virtual Assist” section on page 78
“Configuring Virtual Assist Settings” section on page 79

“Using the Request Assistance Feature” section on page 97

Understanding Virtual Assist

Virtual Assist is fully supported on Windows platforms. Virtual Assist is certified to work on Windows 7, Windows Vista and Windows XP. Limited functionality is supported on MAC OS where customers can request for assistance via web-requests.
Note When a user requests service as a customer, Virtual Assist should not be run while
connected to the system via RDP for Windows 7 and Windows Vista platforms. V irtual Assist runs as a service for proper access to the customer’s system, so correct permissions cannot be set if it is run from an RDP connection.
There are two sides to a Virtual Assist session: the customer view and the technician view . The customer is the person requesting assistance on their computer. The technician is the person providing assistance. A Virtual Assist session consists of the following sequence of events:
1. The technician launches Virtual Assist from the SonicWALL SSL VPN Virtual Office.
2. The technician monitors the Assistance Queue for customers requesting assistance.
3. The customer requests assistance by one of these methods:
Logs into the SonicWALL SSL VPN Virtual Office and clicks on the Virtual Assist link.

6. The technician clicks on the customers name and launches a Virtual Assist session.
7. The technician’s Virtual Assist window now displays the customers entire display. The
technician has complete control of the customer computer’s mouse and keyboard. The customer sees all of the actions that the technician performs.
8. If at anytime the customer wants to end the session, they can take control and click on an
End Virtual Assist button in the bottom right corner of the screen.
9. When the session ends, the customer resumes sole control of the computer.

This is useful if one technician needs to hand the user off to another technician, because of differing areas of expertise or the end of shift.

Using File Shares

Using File Shares
File shares provide remote users with a secure Java applet or HTML-based interface to Microsoft File Shares using the CIFS (Common Internet File System) or SMB (Server Message Block) protocols. Using a Web interface similar in style to Microsoft’s familiar Network Neighborhood or My Network Places, File Shares allow users with appropriate permissions to browse network shares, rename, delete, retrieve, and upload files, and to create bookmarks for later recall.
The File Shares Applet mimics Windows Explorer navigation and provides functionality not available in HTML-based File Shares, including the ability to overwrite existing files and upload directories.
This section contains the following subsections:
“Using the File Shares Applet” section on page 97
“Using HTML-Based File Shares” section on page 111

Using the File Shares Applet

The File Shares Applet has a similar look and feel to the Windows Explorer tool, featuring drag­and-drop and multiple file selection capabilities. It also provides the user the ability to set up bookmarks to quickly navigate through networks from the portal level. This feature saves time lost moving through network and server paths. The File Shares Applet leverages Sun’s Java platform browser plug-in to increase usability by mimicking the common Windows Explorer interface. With the help of the HTTPS protocol, the applet securely transfers encrypted files and information to and from the SSL-VPN appliance. The appliance communicates this data to the individual machines on the remote network.
