Can't connect to the Cisco VPN 3000 Concentrator with the Cisco VPN Client - client receives "remote peer terminated connection" message

Core issue

This message on the VPN Client indicates that no address pool is configured. Another option is that there is no assignment mode on the Cisco VPN 3000 Concentrator.

The following log is seen on the VPN Concentrator, in addition to the error message seen on the VPN Client:

826 11/28/2001 16:22:48.640 SEV=7 IKEDBG/42 RPT=1
Group [vpn3000] User [ciscouser]
IKE received response of type [FAILED] to a request from the IP address utility

Cannot obtain an IP address for remote peer


Proceed with the following steps on the VPN Concentrator:

  1. Go to Configuration > System > Address Management > Pools, and add a small pool of free addresses on the internal network.
  2. Go to Configuration > System > Address Management > Assignment, and select only Use Address Pools.
  3. Try connecting the VPN Client to the VPN Concentrator.
