Platform Compatibility
The SonicWALL SSL-VPN 2.1 release is supported on the following platforms:
•SonicWALL SSL-VPN 2000
•SonicWALL SSL-VPN 4000
New Features
The following features are introduced in the SonicWALL SSL-VPN 2000/4000 2.1 release:
•File Shares Java Applet—The File Shares Java Applet is a Java Virtual Machine (JVM) Web
browser plug-in for remote users that provides improved navigation when using File Shares to
access to shared network resources. Using the File Shares Java Applet, files and folders can be
moved by drag-and-drop and multiple files and folders can be transferred with a single command.
From the SSL-VPN portal, select HTML or Java File Shares application to launch by default.
•LDAP Multiple Organizational Unit (OU) support—Provides LDAP authentication capability for
multiple organizational units (OUs) using multiple base distinguished names (baseDNs), including
authentication of LDAP accounts in nested sub-OUs without additional configuration. Additionally,
users can login as an LDAP user with a common name (CN) or user ID (UID), rather than a DN.
•Active Directory (AD) Group support—Provides access control based on existing AD group
memberships. If a SonicWALL SSL-VPN group has one or more AD groups associated with it,
only users from the associated AD groups will have access to that SSL-VPN group. SonicWALL
SSL-VPN groups that are not associated with AD group(s) can be accessed by any user from the
AD domain. By creating an “SSL-VPN User” group on the AD server and configuring the
SonicWALL SSL-VPN to only accept members from that group, administrators can effectively
limit SSL-VPN logins to specific AD users.
•RADIUS Filter-ID Group support—Provides access control based on existing RADIUS group
memberships using the RADIUS Filter-ID attribute. If a SonicWALL SSL-VPN group has one or
more RADIUS groups associated with it, only users from the associated RADIUS groups will have
access to the SonicWALL group. SonicWALL SSL-VPN groups that are not associated with
RADIUS groups can be accessed by any user from the RADIUS domain.

•Support for GMS/ViewPoint Reporting—SonicWALL SSL-VPN will support GMS and
ViewPoint 4.1, which will be available later in 2007, by routing Syslog messages to a ViewPoint
server for reporting and monitoring. Events that trigger a Syslog delivery to the server include:
Reverse proxy, NetExtender, RDP, VNC, FTP, SSH/SSHv2, Telnet, export diagnostics, export
config file, restart, and restore defaults.
•ViewPoint manual key licensing requirements—The SonicWALL SSL-VPN 2000 appliance
requires the purchase and manual entry of a key in order to enable ViewPoint functionality.
Support will be for ViewPoint 4.1, which will be available later in 2007.
•NetExtender enhancements—There are numerous enhancements to NetExtender in the
SonicWALL SSL-VPN 2.1 release, including:

•Various performance improvements, including cleaned up lock files, deletion of policies upon
disconnect, and removal of the netExtenderLog utility
•Classful subnet route removed by the NetExtender client after the client connects
•NetExtender does not re-launch with homepage CGI reloads
•Full compatibility with Windows Vista. When launched from the portal, select the option to
“run as administrator” and ensure that protected mode is turned off.
•Improved reconnection after a break in network connection: If the IP pool is exhausted, the
old connection is killed and the IP address from that connection is reused
•When NetExender is launched from a portal session, the portal timeout will only count down
when there is no traffic across the NetExtender tunnel
•When NetExtender is launched from the portal, upon user logout using the Logout button or
user logout by the administrator, the NetExtender session is also logged out
•Server-level control of user name and password storage in NetExtender standalone client,
allowing users to save user name and password if the server allows
•New administrator configuration options, including automatically exiting the NetExtender
client after disconnect, forcing an uninstall of the client after exit, creating a client connection
profile, and controlling username and password caching options
•Global tunnel-all control with added ability for user-level settings to inherit group and global
tunnel-all settings

Rev A 02/07
•Reverse Proxy enhancements—HTTP(S) reverse proxy now supports Windows SharePoint
Services 2.0, a Web portal management tool. All features in Windows SharePoint Services are
supported except those that require integration with the client program.
•Variable HTTP(S) and CIFS Bookmark settings—Provides the option to create a single
bookmark that allows multiple users to access paths that have variable usernames in them by
creating a bookmark with the case-sensitive variable %USERNAME%, where %USERNAME% is
replaced with the current user’s username. For example, if an administrator creates a bookmark
named %USERNAME%’s Home with a link to \\1.2.3.4\&USERNAME%, a user (with access to
the bookmark under policy) who logs in with the username BSmith will see a bookmark named
BSmith’s Home that links to \\1.2.3.4\BSmith. This variable can also be used for CIFS access
policies.
•RDP ActiveX enhancements—RDP ActiveX enhancements include RDP6 support, encryption
for sensitive parameters, proxy support that includes HTTPS proxy and automatic use of Internet
Explorer proxy settings, and RDP5 ActiveX bookmarks that now work with custom ports.
•SSHv2 Applet enhancements—SSHv2 Applet enhancements include a status bar that displays
SSHv2 activity, an option to automatically accept a server host key to more efficiently connect to
a trusted server, and an option to bypass the username requirement for SSHv2 servers without
authentication.
•New diagnostic utilities—DNS lookup and Traceroute diagnostic utilities have been added to
the management interface under System > Diagnostics.
•RADIUS Domain authentication support—Added support for the following RADIUS Domain
authentication methods: PAP, CHAP, MSCHAP, MSCHAPV2.
•Additional enhancements—Additional enhancements in the SSL-VPN 2.1 release include:
oAdministrator control over local users’ ability to change password
oSupport for changing passwords for LDAP domains
oFor Active Directory users, new error message if appliance clock is not in sync with the
AD server
oSupport for longer filenames in FTP

Known Issues
This section contains a list of known issues in the SonicWALL SSL-VPN 2000/4000 2.1 release.
•43379: Symptom: Digest access authentication fails with IIS 6.0 and the SSL-VPN security
appliance. Condition: Occurs when access to a Web server running IIS 6.0 is set to use digest
authentication, and a reverse proxy bookmark on the SSL-VPN is used to reach the Web server.
Workaround: For servers using IIS 6.0, reconfigure the server to use basic or anonymous HTTP
authentication. Alternatively, run IIS 5.0 or Apache on the Web server, either of which work with
digest authentication through the SSL-VPN.
•47266: Symptom: A NetExtender session launched from the portal does not connect when using
a proxy server with authentication. If no authentication is configured for the proxy server, the
NetExtender user interface does not display until the portal window is closed. Condition: Occurs
when using a proxy server with or without authentication configured.

Resolved Known Issues
The following issues are resolved in the SonicWALL SSL-VPN 2000/4000 2.1 release:
•41861: Symptom: The SSL-VPN security appliance does not authenticate user accounts in some
instances. Condition: Occurs when the user account is defined within a nested organizational
unit (sub-OU) and LDAP is used for authentication. Workaround: Configure a domain for each
OU, including each sub-OU.
•44868: Symptom: Users see a blank Web page when trying to access a Sharepoint portal
through the SSL-VPN security appliance. Condition: Occurs when an HTTP bookmark to the
Sharepoint portal is created on the SSL-VPN appliance, and the user selects the bookmark to
access Sharepoint. Workaround: Instead of using the bookmark, click NetExtender on the SSL-
VPN screen to access the internal network, and then use a local Web browser to access the
Sharepoint portal.
•46012: Symptom: Portal home page and login message files cannot be deleted from the SSL-
VPN security appliance after loading a configuration without the portal. Condition: Occurs when
you create a portal layout on the appliance, and then import a configuration that does not contain
the portal. The LoginMessage.txt, HomeMessage.txt, and HomeInclude.html files for the portal
cannot be deleted because the portal is gone. Workaround: Create another portal layout with the
same name as the missing one, and then delete it. The files are deleted when the portal layout is
deleted.
•46028: Symptom: CIFS Access Policy can fail to block access. Condition: Occurs when a CIFS
bookmark is created, and then a CIFS access policy is created that denies access to the file
share that is bookmarked.
•46881: Symptom: CIFS and HTTP bookmark paths containing spaces disappear after the
appliance is restarted. Condition: Occurs when a space is included in a CIFS or HTTP
bookmark.
•46533: Symptom: Delayed access to file shares when User policies are created to deny access
to an IP address or an IP address range. Condition: Occurs when deny policies are created for
an IP address or an IP address range and a simultaneous allow policy is created for an IP
address or IP address range that is also included in the deny policy.

Upgrading SonicWALL SSL-VPN Software Procedures
The following procedures are for upgrading an existing SonicWALL SSL-VPN image to a newer version.
•OBTAINING THE LATEST SONICWALL SSL-VPN IMAGE VERSION
•EXPORTING A COPY OF YOUR CONFIGURATION SETTINGS
•ARCHIVING OTHER CRITICAL INFORMATION
•UPLOADING A NEW SONICWALL SSL-VPN IMAGE
•RESETTING THE SONICWALL SSL-VPN 2000 OR 4000 USING SAFEMODE
Obtaining the Latest SonicWALL SSL-VPN Image Version
1. To obtain a new SonicWALL SSL-VPN image file for your SonicWALL security appliance, connect to
your mysonicwall.com account at <http://www.mysonicwall.com>.
Note: If you have already registered your SonicWALL SSL-VPN appliance, and you selected
Notify me when new firmware is available on the System > Settings page, you are automatically
notified of any updates available for your model.
2. Copy the new SonicWALL SSL-VPN image file to a directory on your management station.
Exporting a Copy of Your Configuration Settings
Before beginning the update process, export a copy of your SonicWALL SSL-VPN appliance
configuration settings to your local machine. The Export Settings feature saves a copy of your current
configuration settings on your SonicWALL SSL-VPN appliance, protecting all your existing settings in the
event it becomes necessary to return to a previous configuration state.
Perform the following procedures to save a copy of your configuration settings and export them to a file
on your local management station:
1. Click the Export Settings . . . button on the System > Settings page and save the settings file to
your local machine. The default settings file is named sslvpnSettings.zip. You can rename the file but
you should keep the .zip filename.
Tip: Rename the .zip file to include the version of the SonicWALL SSL-VPN image from which
you are exporting the settings. For example, if you export the settings from the SonicWALL SSL-VPN
1.5.0.0 image, rename the file using the format: [date]_[version]_[mac].zip to “041606_SSL-
VPN_1.5.0.0-19_0006B1223344.zip” (the [mac] format entry is the serial number of the SonicWALL
security appliance). Then if you need to roll back to that version of the SonicWALL SSL-VPN mage,
you can choose the correct file to import.

Resetting the SonicWALL SSL-VPN 2000 or 4000 Using SafeMode
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 reset the SonicWALL security appliance, perform the following steps:
1. Connect your management station to a LAN port on the SonicWALL security appliance and
configure your management station IP address with an address on the 192.168.200.0/24 subnet,
such as 192.168.200.20.
Note: The SonicWALL security appliance can also respond to the last configured LAN IP
address in SafeMode. This is useful for remote management recovery or hands off recovery in a
datacenter.
2. 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 five to ten seconds. The reset button is in a small hole
next to the power supply.
Reset Button – SSL-VPN
