Where can I see Cisco IPSec VPN logs?
This information is available in the Console application. The logging for Cisco IPSec VPN type is associated with the "racoon" service heading (note: only one c in racoon); the logging for IKEv2 is associated with the nesessionmanager service. It is unclear to me whether these messages are captured in a persistent log, but they do at least show up when Console is open and a VPN connection is created/initiated.
