4 What version of Java do I need?
Answer: You should install SUN's JRE 1.6.0_10 or higher (available at http://www.java.com) to use
some of the features on the SMA/SRA appliance. On Google Chrome, you need Java 1.6.0 update 10 or
higher.
5 What operating systems are supported?
Answer:
• Microsoft Vista
• Microsoft Windows 7
• Apple OSX 10.6.8 and newer
• Linux kernel 2.6.x and newer
6 Why does the 'File Shares' component not recognize my server names?
Answer: If you cannot reach your server by its NetBIOS name, there might be a problem with name
resolution. Check your DNS and WINS settings on the SMA/SRA appliance. You might also try manually
specifying the NetBIOS name to IP mapping in the Network > Host Resolution section, or you could
manually specify the IP address in the UNC path, for example \\192.168.100.100\sharefolder.
Also, if you get an authentication loop or an error, is this File Share a DFS server on a Windows domain
root? When creating a File Share, do not configure a Distributed File System (DFS) server on a Windows
Domain Root system. Because the Domain Root allows access only to Windows computers in the domain,
doing so disables access to the DFS file shares from other domains. The SMA/SRA appliance is not a
domain member and is not able to connect to the DFS shares. DFS file shares on a stand-alone root are
not affected by this Microsoft restriction.
7 Does the SMA/SRA appliance have an SPI firewall?
Answer: No. It must be combined with a Dell SonicWALL security appliance or other third-party
firewall/VPN device.
8 Can I access the SMA/SRA appliance using HTTP?
Answer: No, it requires HTTPS. HTTP connections are immediately redirected to HTTPS. You might wish
to open both 80 and 443, as many people forget to type https: and instead type 
http://. If you block 80, it is not redirected.
9 What is the most common deployment of the SMA/SRA appliances?
Answer: One-port mode, where only the X0 interface is utilized, and the appliance is placed in a
separated, protected "DMZ" network/interface of a Dell SonicWALL security appliance, such as a Dell
SonicWALL TZ or NSA appliance.
10 Why is it recommended to install the SMA/SRA appliance in one-port mode with a Dell SonicWALL
security appliance?
Answer: This method of deployment offers additional layers of security control plus the ability to use
Dell SonicWALL's Unified Threat Management (UTM) services, including Gateway Anti-Virus, Anti-
Spyware, Content Filtering and Intrusion Prevention, to scan all incoming and outgoing NetExtender
traffic.
11 Is there an installation scenario where you would use more than one interface or install the appliance in
two-port mode?
Answer: Yes, when it would be necessary to bypass a firewall/VPN device that might not have an
available third interface, or a device where integrating the SMA/SRA appliance might be difficult or
impossible.
12 Can I cascade multiple SMA/SRA appliances to support more concurrent connections?
Answer: No, this is not supported.
13 Why can't I log in to the Secure Mobile Access management interface of the SMA/SRA appliance?
Answer: The default IP address of the appliance is 192.168.200.1 on the X0 interface. If you cannot
reach the appliance, try cross-connecting a system to the X0 port, assigning it a temporary IP address of
Dell SonicWALL Secure Mobile Access 8.5
