SonicOS 5.8.1 Administrator Guide
increases the efficiency of your SonicWALL security appliance by providing you the ability 
to configure user view settings and filter junk messages before users see it in their inboxes. 
The following enhancements are now available with CASS 2.0: 
  –
The Email Security Junk Store application can now reside outside the Exchange Server 
system. Unlike in version 1.0, Junk Store can now be installed on another remote 
server. 
  –
Dynamic discovery of Junk Store user interface pages has been added. This feature 
allows the Junk Store to inform SonicOS of a list of pages to display under Anti-Spam 
in the SonicOS left hand navigation pane. For example, the pane might show Junk Box 
View, Junk Box Settings, Junk Summary, User View Setup, and/or Address Books.
  –
User-defined Allow and Deny Lists can now be configured with FQDN and Range 
address objects in addition to Host objects.
  –
A GRID IP Check tool has been added in the Anti-Spam > Status page. The SonicWALL 
administrator can specify (on-demand) an IP address to check against the SonicWALL 
GRID IP server. The result will either be LISTED or UNLISTED. Connections from a 
LISTED host will be blocked by the SonicWALL security appliance running CASS 
(unless overridden in the Allow List).
  –
A parameter to specify the Probe Response Timeout is added in the Anti-Spam > 
Settings page Advanced Options section. There are deployment scenarios where a 
longer timeout is needed to prevent a target from frequently being marked as 
Unavailable. The default value is 30 seconds.
  •
Enhanced Connection Limiting - Connection Limiting enhancements expand the original 
Connection Limiting feature which provided global control of the number of connections for 
each IP address. This enhancement is designed to increase the granularity of this kind of 
control so that the SonicWALL administrator can configure connection limitation more 
flexibly. Connection Limiting uses Firewall Access Rules and Policies to allow the 
administrator to choose which IP address, which service, and which traffic direction when 
configuring connection limiting.
  •
Dynamic WAN Schedule - SonicOS 5.8.0.0 supports scheduling to control when Dynamic 
WAN clients can connect. A Dynamic WAN client connects to the WAN interface and 
obtains an IP address with the PPPoE, L2TP, or PPTP. This enhancement allows the 
administrator to bind a schedule object to Dynamic WAN clients so that they can connect 
when the schedule allows it and they are disconnected at the end of the configured 
schedule. In the SonicOS management interface, a Schedule option is available on the 
WAN interface configuration screen when one of the above protocols is selected for IP 
Assignment. Once a schedule is applied, a log event is recorded upon start and stop of the 
schedule.
  •
NTLM Authentication with Mozilla Browsers - As an enhancement to Single Sign-On, 
SonicOS can now use NTLM authentication to identify users who are browsing using 
Mozilla-based browsers (including Internet Explorer, Firefox, Chrome and Safari). NTLM is 
part of a browser authentication suite known as "Integrated Windows Security" and should 
be supported by all Mozilla-based browsers. It allows a direct authentication request from 
the SonicWALL appliance to the browser with no SSO agent involvement. NTLM 
authentication works with browsers on Windows, Linux and Mac PCs, and provides a 
mechanism to achieve Single Sign-On with Linux and Mac PCs that are not able to 
interoperate with the SSO agent.
  •
SSL VPN NetExtender Update - This enhancement supports password change capability 
for SSL VPN users, along with various fixes. When the password expires, the user is 
prompted to change it when logging in via the NetExtender client or SSL VPN portal. It is 
supported for both local users and remote users (RADIUS and LDAP).
