Answer: In order for the Web cache cleaner to run, you must click on the Logout button. If you
close the Web browser using any other means, the Web cache cleaner cannot run.
What does the 'encrypt settings file' checkbox do?
30.
Answer: This setting will encrypt the settings file so that if it is exported it cannot be read by
unauthorized sources. Although it is encrypted, it can be loaded back onto the SonicWALL SSL-
VPN appliance (or a replacement appliance) and decrypted. If this box is not selected, the
exported settings file is clear-text and can be read by anyone.
What does the 'store settings' button do?
31.
Answer: By default, the settings are automatically stored on a SSL-VPN 2000 and SSL-VPN
4000 appliance any time a change to programming is made, but this can be shut off if desired.
If this is disabled, all unsaved changes to the appliance will be lost. This feature is most useful
when you are unsure of making a change that may result in the box locking up or dropping off
the network. If the setting is not immediately saved, you can power-cycle the box and it will
return to the previous state before the change was made.
What does the 'create backup' button do?
32.
Answer: This feature allows you to create a backup snapshot of the firmware and settings into
a special file that can be reverted to from the management interface or from SafeMode.
SonicWALL strongly recommends creating system backup right before loading new software,
or making significant changes to the programming of the appliance. This feature is available
only on the SonicWALL SSL-VPN 2000 and SSL-VPN 4000 appliances.
What is 'SafeMode'?
33.
Answer: SafeMode is a feature of the SonicWALL SSL-VPN appliance that allows
administrators to switch between software image builds and revert to older versions in case a
new software image turns out to cause issues. In cases of software image corruption, the
appliance will boot into a special interface mode that allows the administrator to choose which
version to boot, or load a new version of the software image.
How do I access the SafeMode menu?
34.
Answer: In emergency situations, you can access the SafeMode menu by holding in the Reset
button on the SSL-VPN appliance (the small pinhole button located on the front of the SSL-VPN
2000 or SSL-VPN 4000, and on the back of the SSL-VPN 200) for 12-14 seconds until the 'Test'
LED begins quickly flashing yellow. Once the SonicWALL has booted into the SafeMode menu,
assign a workstation a temporary IP address in the 192.168.200.x subnet, such as
192.168.200.100, and attach it to the X0 interface on the SSL-VPN appliance. Then, using a
modern Web browser (Microsoft IE6.x+, Mozilla 1.4+), access the special SafeMode GUI using
the appliance's default IP address of 192.168.200.1. You will be able to boot the appliance
using a previously saved backup snapshot, or you can upload a new version of software with
the Upload New Software image button.
Can I change the colors of the portal pages?
35.
Answer: This is not supported in the current releases, but is planned for a future software
release.
What authentication methods are supported?
36.
Answer: Local database, RADIUS, Active Directory, NT4, and LDAP.
I configured my SonicWALL SSL-VPN appliance to use Active Directory as the
37.
authentication method, but it fails with a very strange error message. Why?
Answer: The appliances must be precisely time-synchronized with each other or the
authentication process will fail. Ensure that the SonicWALL SSL-VPN appliance and the Active
Directory server are both using NTP to keep their internal clocks synchronized.
My Windows XPSP2 system cannot use the RDP-based connectors. Why?
38.
