Release Notes for VPN Client, Release 4.0 through Release 4.0.5.D
OL-5450-10
Usage Notes
Use Zone Labs Integrity Server 2.1.052.0 or Higher with VPN
Client 4.0
Versions of the Zone Labs Integrity Server earlier than 2.1.052.0 exhibit the
following problem. If two or more VPN Clients (running on Windows 2000 or
XP) are connected to a VPN 3000 Series Concentrator and receive firewall policy
from a ZoneLabs Integrity Server, the Integrity Server registers only one
connection.
On the Integrity Flex (client agent), under “Policies”, the “Integrity Server”
column flashes “Connected” then “Disconnected” over and over. Also, the VPN
Client log includes the following event: “The firewall, configured for
Client/Server, returned a status of lost connection to server.” Zone Labs Integrity
Server version 2.1.052.0 fixes this issue (CSCea66549).
Restart VPN Client Service If You Install VPN Client Before Zone
Alarm
The Firewall Enhancement, “Prevent VPN Traffic Blocking”, automatically adds
the Loopback address (127.0.0.1) and the address of the VPN 3000 Concentrator
to the ZoneAlarm or ZoneAlarmPro trusted zone.
An exception to this, however, occurs if the VPN Client is installed before Zone
Alarm. Then the VPN Client’s service must be restarted by rebooting the PC or
stopping and restarting the service through the Control Panel (on Windows
NT-based PCs) (CSCea16012).
InstallShield Error Might occur during VPN Client Installation
The following error message might occur during VPN Client installation:
IKernel.exe - Application Error
The instruction at “0x771c741a” referenced memory at “0x00163648”. The
memory could not be “read”.
This error is caused by an InstallShield component, possibly because of a
run-once stale remnant. To recover, you must reboot.
