STATUS_FWP_EM_NOT_SUPPORTED

The IKE policy cannot contain an Extended Mode policy

Extended Mode is an additional IPsec/AuthIP policy component. This status reports a policy-construction error: the selected IKE policy type does not accept Extended Mode settings.

Determine which Extended Mode requirement the policy selected and whether the current platform and peer support it. Fall back only through a documented compatible policy, not by suppressing the returned status.

What to inspect

  • Remove Extended Mode from policy types that cannot carry it.
  • Check whether the policy was intended for AuthIP rather than plain IKE.
  • Record the exact policy provider and layer where the policy was added.
