VPN Concentrator 3005 drops connections

[CSCO10662744_2]

We have a VPN Concentrator 3005 for employees to connect from home or off sites. Recently some users have reported dropped VPN connections, even though their Internet connection is ok. Below is part of th log, could someone please tell me what needs to be done to fix it?

First, turn on the Cisco VPN client logging and up the logging level:

Log | Enable (if not already enabled)

Log | Log Settings (set all items to 3 - High, select ok)

Have the user select Log | Window in their VPN client so it is visible. Have them login to your VPN. Check the users logs for any errors.

=Cisco Concentrator=

- check for version limitations on what client they can use (users get disconnected w/out a message and concentrator does not point this little item out when it happens)

Configuration | User Management | Groups | IPSec (Client Type & Version limiting)
