Caveats Resolved in Release 4.0.2.B
Release 4.0.2.B resolves the following issues:
CSCeb19862
VPN Clients, version 4.0.x, do not produce an informative Delete with
Reason message when the VPN Concentrator has been configured to
disconnect the Client due to “Type and Version Limiting”.
Type and Version Limiting was introduced with the 4.1 Concentrator code
and does not trigger an informative message from the VPN Client. The
current message is:
Secure VPN Connection terminated by Peer.
Reason: Unknown Error Occurred at Peer.
CSCeb40034
The VPN Client is terminating the connection prematurely during rekey.
The scenario is:
1. The initial IKE SA (SA1) comes up.
2. Rekey is initiated. P1 is complete by establishing SA2.
3. Xauth is in progress.
4. SA1 is deleted. In this case, the remote peer sends a Delete message.
5. The VPN Client detects that there is no user authenticated IKE SA in the
system and brings down the connection.
Although SA2 is not yet authenticated, it is still a valid IKE SA. The VPN
Client should not bring down the connection at this point and should let the
rekey complete.
