SSL_VPN SSL_VPN SSL VPN This section provides information on how to configure the SSL VPN features on the Dell SonicWALL network security appliance. SonicWALL’s SSL VPN features provide secure remote access to the network using the NetExtender client. NetExtender is an SSL VPN client for Windows, Mac, or Linux users that is downloaded transparently and that allows you to run any application securely on the company’s network. It uses Point-to-Point Protocol (PPP). NetExtender allows remote clients seamless access to resources on your local network.
Users can access NetExtender two ways: • Logging in to the Virtual Office web portal provided by the Dell SonicWALL network security appliance and clicking on the NetExtender button. • Launching the standalone NetExtender client.
The NetExtender standalone client is installed the first time you launch NetExtender. Thereafter, it can be accessed directly from the Start menu on Windows systems, from the Application folder or dock on MacOS systems, or by the path name or from the shortcut bar on Linux systems.

Topics: • • • What is SSL VPN NetExtender? SonicWALL’s SSL VPN NetExtender feature is a transparent software application for Windows, Mac, and Linux users that enables remote users to securely connect to the remote network. With NetExtender, remote users can securely run any application on the remote network. Users can upload and download files, mount network drives, and access resources as if they were on the local network.
The NetExtender connection uses a Point-to-Point Protocol (PPP) connection. 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 with the XPCOM plugin when using Firefox. On MacOS systems, supported browsers use Java controls to automatically install NetExtender from the Virtual Office portal. Linux systems can also install and use the NetExtender client.
After installation, NetExtender automatically launches and connects a virtual adapter for secure SSL-VPN 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 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 or Mac. 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 will first uninstall the old NetExtender and install the new version. Once 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. Mac users can launch NetExtender from their system Applications folder, or drag the icon to the dock for quick access. 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. Client Routes NetExtender client routes are used to allow and deny access for SSL VPN users to various network resources. Address objects are used to easily and dynamically configure access to network resources. Tunnel All Mode Tunnel All mode routes all traffic to and from the remote user over the SSL VPN NetExtender tunnel—including traffic destined for the remote user’s local network. This is accomplished by adding the following routes to the remote client’s route table: IP Address Subnet mask 0.0.0.0 0.0.0.0 0.0.0.0 220.127.116.11 18.104.22.168 22.214.171.124 NetExtender also adds routes for the local networks of all connected Network Connections.
These routes are configured with higher metrics than any existing routes to force traffic destined for the local network over the SSL VPN tunnel instead. For example, if a remote user is has the IP address 10.0.67.64 on the 10.0.*.* network, the route 10.0.0.0/255.255.0.0 is added to route traffic through the SSL VPN tunnel. Tunnel All mode is configured on the SSL VPN >Client Routes page. Connection Scripts SonicWALL SSL VPN provides users with the ability to run batch file scripts when NetExtender connects and disconnects. The scripts can be used to map or disconnect network drives and printers, launch applications, or open files or Web sites.
NetExtender Connection Scripts can support any valid batch file commands. Proxy Configuration SonicWALL SSL VPN supports NetExtender sessions using proxy configurations. Currently, only HTTPS proxy is supported. When launching NetExtender from the Web portal, if your browser is already configured for proxy access, NetExtender automatically inherits the proxy settings. The proxy settings can also be manually configured in the NetExtender client preferences. NetExtender can automatically detect proxy settings for proxy servers that support the Web Proxy Auto Discovery (WPAD) Protocol.
NetExtender provides three options for configuring proxy settings: • Automatically detect settings - To use this setting, the proxy server must support Web Proxy Auto Discovery Protocol (WPAD)), which can push the proxy settings script to the client automatically. • Use automatic configuration script - If you know the location of the proxy settings script, you can select this option and provide the URL of the script. • Use proxy server - You can use this option to specify the IP address and port of the proxy server. Optionally, you can enter an IP address or domain in the BypassProxy field to allow direct connections to those addresses and bypass the proxy server. If required, you can enter a user name and password for the proxy server.
If the proxy server requires a username and password, but you do not specify them, a NetExtender pop-up window will prompt you to enter them when you first connect. When NetExtender connects using proxy settings, it establishes an HTTPS connection to the proxy server instead of connecting to the firewall server directly. The proxy server then forwards traffic to the SSL VPN server.
All traffic is encrypted by SSL with the certificate negotiated by NetExtender, of which the proxy server has no knowledge. The connecting process is identical for proxy and non-proxy users. Configuring Users for SSL VPN Access For users to be able to access SSL VPN services, they must be assigned to the SSLVPN Services group. Users who attempt to login through the Virtual Office who do not belong to the SSLVPN Services group will be denied access. The following sections describe how to configure user accounts for SSL VPN access: • • • Configuring SSL VPN Access for Local Users To configure users in the local user database for SSL VPN access, you must add the users to the SSLVPN Services user group. To do so, perform the following steps: 1. Navigate to the Users >Local Users page.
