Benefits
NetExtender provides remote users with full access to your protected internal network. The experience is
virtually identical to that of using a traditional IPSec VPN client, but NetExtender does not require any manual
client installation. Instead, the NetExtender Windows client is automatically installed on a remote user's PC by
an ActiveX control when using the Internet Explorer browser or Firefox. On Linux systems, supported browsers
use Java controls to automatically install NetExtender from the Virtual Office portal.
The NetExtender Windows client also has a custom-dialer that allows it to be launched from the Windows
Network Connections menu. This custom-dialer allows NetExtender to be connected before the Windows
domain login. The NetExtender Windows client also supports a single active connection, and displays real-time
throughput and data compression ratios in the client.
After installation, NetExtender automatically launches and connects a virtual adapter for SSL-secure
NetExtender point-to-point access to permitted hosts and subnets on the internal network.
NetExtender Concepts
The following sections describe advanced NetExtender concepts:
• Stand-Alone Client
• Multiple Ranges and Routes
• NetExtender with External Authentication Methods
• Point to Point Server IP Address
• Connection Scripts
• Tunnel All Mode
• Proxy Configuration
Stand-Alone Client
Secure Mobile Access provides a stand-alone NetExtender application. NetExtender is a browser-installed
lightweight application that provides comprehensive remote access without requiring users to manually
download and install the application. The first time a user launches NetExtender, the NetExtender stand-alone
client is automatically installed on the user's PC. The installer creates a profile based on the user's login
information. The installer window then closes and automatically launches NetExtender. If the user has a legacy
version of NetExtender installed, the installer first uninstalls the old NetExtender and installs the new version.
After the NetExtender stand-alone client has been installed, Windows users can launch NetExtender from their
PC's Start > Programs menu and configure NetExtender to launch when Windows boots.
NetExtender can establish a VPN session before the user logs into the Windows domain. For Windows Vista or
later, users can click Switch User on the Windows login screen and click the blue computer icon that appears at
the right bottom of the screen to view the dialup connection list, and then can select NetExtender to connect.
On Linux systems, the installer creates a desktop shortcut in /usr/share/NetExtender. This can be dragged to
the shortcut bar in environments like Gnome and KDE.
NetExtender is compatible with the following Dell SonicWALL appliances:
• SMA 400/200
• SRA 4600/1600
• SMA 500v Virtual Appliance

connectivity.
