Release Notes for VPN Client, Release 4.0 through Release 4.0.5.D
OL-5450-10
• CSCdy70168
A user with the VPN Client cannot establish an IPSec tunnel to a VPN
Concentrator running over an Internet satellite connection.
There are three observed results:
– User is never prompted for XAUTH username and password.
– After successfully authenticating, the user cannot transmit/receive any
data.
– After successfully transmitting data for approximately 5 minutes, the
VPN session is disconnected regardless of the user activity at the time of
disconnect.
This problem occurs only if IPSec over TCP is used.
Workaround:
Use IPSec over UDP.

The following error might occur on Windows 98 when making many VPN
connections without closing the VPN Client between connections:
VPNGUI caused an invalid page fault in module MSVCRT.DLL at
0167:78002f52.
To avoid this error, exit the VPN Client after disconnecting.
• CSCdz48584
The VPN Client on Windows XP using native XP PPPoE client fails to
connect when using IPSec/TCP.
Workaround:
Make sure that the Windows XP Internet Connection Firewall is disabled for
the PPPoE connection. This feature defaults to enabled when the connection
entry is created. To disable it do the following:
Step 1 Run Control Panel, then click on Network Connections.
Step 2 Right click on the PPPoE connection entry (may be called “Broadband”) and
select “Properties”.
