required memory. Note that gzip compression is not available on the local (clear text side) of the
SMA/SRA appliance, or for HTTPS requests from the remote client.
17 The SMA/SRA appliance is application dependent; how can I address non-standard applications?
Answer: You can use NetExtender to provide access for any application that cannot be accessed using
internal proxy mechanisms - HTTP, HTTPS, FTP, RDP5, Telnet, SSHv1, and SSHv2. Application Offloading
can also be used for Web applications. In this way, the SMA/SRA appliance functions similar to an SSL off
loader and proxies Web applications pages without the need for URL rewriting.
18 Why is it required that an ActiveX component be installed?
Answer: NetExtender is installed through an ActiveX-based plug-in from Internet Explorer. Users using
Firefox browsers can install NetExtender through an XPI installer. NetExtender can also be installed
through an MSI installer. Download the NetExtender MSI installer from mysonicwall.com.
19 Does NetExtender support desktop security enforcement, such as AV signature file checking, or Windows
registry checking?
Answer: Not at present, although these sorts of features are planned for future releases of NetExtender.
20 Does NetExtender work with the 64-bit version of Microsoft Windows?
Answer: Yes, NetExtender supports 64-bit Windows 7 and Vista.
21 Does NetExtender work 32-bit and 64-bit version of Microsoft Windows 7?
Answer: Yes, NetExtender supports 32-bit and 64-bit Windows 7.
22 Does NetExtender support client-side certificates?
Answer: Yes, Windows NetExtender client supports client certificate authentication from the stand-
alone client. Users can also authenticate to the Secure Mobile Access portal and then launch
NetExtender.
23 My firewall is dropping NetExtender connections from my SonicWALL SMA/SRA as being spoofs. Why?
Answer: If the NetExtender addresses are on a different subnet than the X0 interface, a rule needs to be
created for the firewall to know that these addresses are coming from the SMA/SRA appliance.
