Virtual Office Overview

This chapter provides an overview of the SonicWALL SSL VPN user portal. It also includes an introduction to the SRA appliance 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 underly ing 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 SRA security appliance includes several Java or ActiveX thin-client programs that can be launched from within the SonicWALL SRA 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.

SonicWALL SSL VPN 5.5 User Guide

Browser Requirements

For SSL VPN to work as described in this guide, the SonicW ALL SRA security appliance must be installed and configured according to the directions provided in the SonicWALL SRA Getting Started Guide for your model.

• 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 standalone client can be launched directly from users’ computers without requiring them to log in to the SSL VPN portal first.

• Using the SonicWALL Mobile Connect app – SonicWALL Mobile Connect is an app for

iPhone and iPad that, like NetExtender, uses SSL VPN to enable secure, mobile connections to private networks protected by SonicWALL security appliances. For information about installing and using SonicWALL Mobile Connect, see the SonicWALL Mobile Connect User’s Guide available on www.sonicwall.com, at:

http://www.sonicwall.com/app/projects/file_downloader/document_lib.php?t=PG&id=482

Logging into the SSL VPN Virtual Office Using RSA Two-Factor Authentication

To log in to the SonicWALL SSL VPN Virtual Office using RSA two-factor authentication, perform the following steps.

Step 1 Enter the IP address of the SRA appliance in your computers browser. The authentication

window is displayed.

Step 2 Enter your username in the Username field. Step 3 The first time you log in to the Virtual office, your entry in the password field depends on

whether your system requires a PIN:

Using Two-Factor Authentication

–

If you already have a PIN, enter the passcode in the Password field. The passcode is

the user PIN and the SecurID token code. For example, if the user’s PIN is 8675 and

the token code is 30966673, then the passcode is 867530966673.

–

If a PIN is required, but you do not yet have a PIN, enter the SecurID token code in the

Password field. You will be prompted to create a PIN.

–

If the RSA server does not require a PIN, simply enter the SecurID token code.

Note Consult with your network administrator to determine if your configuration reqiures a PIN.

Step 4 Select the appropriate Domain.

VASCO Two-Factor User Authentication Process

The following sections describe user tasks when using RSA two-factor authentication:

• “Logging into the SSL VPN Virtual Office Using VASCO Two-Factor Authentication” on

page 21

• “Creating a New PIN” on page 20

Logging into the SSL VPN Virtual Office Using VASCO Two-Factor Authentication

To log in to the SonicWALL SSL VPN Virtual Office using VASCO two-factor authentication, perform the following steps:

Step 1 Enter the IP address of the SRA appliance in your computer ’s browser. The authentication

window is displayed.

Step 2 Enter your username in the Username field. Step 3 Enter the passcode in the Password field. Y our entry in the password field depends on whether

your system requires a PIN:

–

If you already have a PIN, enter the passcode in the Password field. The passcode is

the user PIN and the VASCO Digipass token code. For example, if the user’s PIN is

8675 and the token code is 30966673, then the passcode is 867530966673.

–

If a PIN is required, but you do not yet have a PIN, enter the VASCO Digipass code in

the Password field. You will be prompted to create a PIN.

–

If the RSA server does not require a PIN, simply enter the VASCO Digipass code.

Note Consult with your network administrator to determine if your configuration reqiures a PIN.

Step 4 Select the appropriate Domain.

Note If manually entering the Domain, it is case-sensitive.

Step 5 Click Login.

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.

Using One-Time Passwords

• 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

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.

SonicWALL SSL VPN 5.5 User Guide

Using NetExtender

Note Only rooted devices are supported for NetExtender Android in SonicWALL SSL VPN.

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.
