Release Notes for 3Com X Family of Unified Security Platforms, Release 3.2 Page 8
Workaround: Configure the client browser to trust the X family certificate, as documented in Appendix
A of the LSM User’s Guide. Alternatively, go to http://3kb.3com.com
for a technical note explaining how
to remove these warnings across an Active Directory domain.
USER LOGIN AND POPUP BLOCKERS
When using the "User Login Status Window" feature (configured in Authentication > Preferences),
any popup blocker on the user’s browser may prevent display of the login status window. This can
result in users being logged out again once the first heartbeat is missed.
Workaround: Ensure that the popup blocker is configured to allow popups from the IP address of the X
family device's virtual interface.
APPLE IPHONE VPN TERMINATION
The Apple iPhone can create VPNs that can terminate in an X family device. For these VPNs to work,
the X family device must be using the Strong Encryption Service Pack, as documented in Chapter 7 of
the LSM User’s Guide.
IPS FILTER OVERRIDES
When you create a filter override to enable a filter, you must select an Action for the filter. Do not leave
the Action set to Recommended.
WEB-BASED SETUP WIZARD
IP Interface Setup
The web-based installation wizard allows you to configure basic X family settings. When you are initially
configuring the IP interfaces, do not select the option to set up the GRE Tunnel interface. This
advanced configuration option should not be selected or configured during initial setup.
After you complete the initial setup, you can configure GRE Tunnel interfaces from the IP Interfaces
page in the LSM (Network > Configuration > IP Interfaces). For details on configuring a GRE tunnel,
see the online help.
Error Message “Unable to configure while NTP client is enabled”
If the device has already been configured and you return to the Setup Wizard to make configuration
changes, you may see this error message: “Unable to configure while NTP client is enabled.” The
installation wizard is trying to set the system clock manually even though NTP is enabled. Ignore this
message and make any necessary configuration changes. When you save the changes, they will be
applied correctly.
WEB FILTER CONFIGURATION
Web Filter Firewall Rule
When you enable Web filtering (Firewall > Web Filter) either for the 3Com Web Content Filtering
Service or to use manual filtering, you must create a firewall rule in the correct position in the firewall
rule table. This rule must be placed such that no higher-precedence rules will match the traffic that
should be subject to the desired Web filter profile.
