  • Hi,

    Are you using certificates or pre-shared keys for L2TP connection?

    If you are using certificates for client and server authentication, do you configure the certificate correctly? We need to use IPsec template to create L2TP certificate.

    Please provide more information about how you configure L2TP connection, it may be of help.

    Besides, you may provide the error code logged in NPS event log.

    Best Regards,
