Cisco VPN Client Random Disconnects

tohoken · ‎05-14-2008

I am connecting to our ASA5510 via Cisco VPN client version 5.x. I am getting continuous disconnects at random times. I have never had a connection last more than 10 minutes. The disconnects happen when the session is idle and also when the session is active. I have had the connection drop on me in the middle of a file transfer even. I have set the session timeout to unlimited but no help. Does anyone have any ideas?

Thanks,

Ken

The reason for that disconnection might be one of the following:

1) You reached an idle timeout.Increase the idle timeout value.

2) Someone cleared the tunnel.check for the tunnel configuration.

3) Your SA has a very short lifetime.

check if isakmp nat-t is enabled.If not enable the same and check for the issue.

check if TunnelEstablished Registry key is set to 0 which is the right one.
