    • Inbound Packets: Displays content of incoming IKE messages
    • Kernel Messaging: Displays communication messages with the Kernel
    • High Availability: Displays communication with other HA nodes

    In the L2TP Debugging section, if you select Enable debug mode, the IPsec VPN log file contains extended information about L2TP or PPP connection negotiation.
