| Severity | Notification |
| Description | Client rejected NAT enabled IPSec request, falling back to standard IPSec |
| Explanation | This message indicates the client rejected an attempt by the Cisco ASA to use IPSec over UDP. IPSec over UDP is used to allow multiple clients to establish simultaneous tunnels to the Cisco ASA through a NAT device. The client may have rejected the request either because it does not support this feature or because it is configured to not use it. |
| User Action | Verify the configuration on the headend and peer. |
