Yes. Are you connecting thru the VP41? or with it? If you are going thru it, you need to set up IPsec passthru, and make sure your settings are correct for the connection to the other end. If you are using the VP41 to make the connection, then you cannot use the client on top of that, that is a VPN tunnel inside of a VPN tunnel, which I would like to say is not going to work using the 3000 series as the only termination point. Provide more information about how you are connecting and what you are trying to do, and we can better help you. Also make sure that you can see, i.e. ping, the cisco 3000 series concentrator.
