Release Notes for VPN Client, Release 4.0 through Release 4.0.5.D
OL-5450-10
Network ICE BlackICE Defender Configuration
Network ICE's BlackICE Defender is a traffic monitoring security product. If you
properly configure it, BlackICE Defender can work with the VPN Client. You
must configure BlackICE Defender for Trusting, Nervous, or Cautious mode. If
you use Nervous or Cautious mode, add the public IP address of the VPN
Concentrator to the list of trusted addresses. You can now configure the VPN
Client to work with BlackICE Defender configured for Paranoid mode when in
Tunnel-everything mode. Split Tunneling requires BlackICE to be in Trusting,
Nervous, or Cautious mode.
The Cisco VPN Client firewall has the following requirements for BlackICE
(BlackICE Defender 2.5 or greater or BlackICE Agent 2.5 or greater). For
BlackICE Defender 2.5, copy the BICTRL.DLL file from the Cisco installation
release medium to the BlackICE installation directory on the VPN Client PC. This
is a mandatory step for making a connection requiring BlackICE.
BlackICE Defender version 2.9 and greater includes the BICTRL.DLL file in the
Network ICE distribution medium, so that you do not need to copy it from the
Cisco installation release medium.
Microsoft Outlook Error Occurs on Connection or Disconnect
The following Microsoft Outlook error might occur when the VPN Client
connects or disconnects:
“Either there is no default mail client, or the current mail client cannot fulfill the
messaging request. Run Microsoft Outlook and set it as the default mail client.”
This message does not affect operation of the VPN Client. The issue occurs when
Microsoft Outlook is installed but not configured for email, although it is the
default mail client. It is caused by a Registry Key that is set when the user installs
Outlook.
To eliminate this message, do one of the following:
• Right-click the Outlook icon, go to Properties, and configure it to use
Microsoft Exchange or Internet Mail as the default mail client.
• Use Internet Explorer to configure the system to have no default mail client.
• Configure Outlook as the default mail client (CSCdv67594).
