STATUS_FWP_INVALID_TRANSFORM_COMBINATION
The IPsec transform set is not a valid combination
IPsec policy is a set of related transforms, not a list of independent algorithms. This status means the selected authentication, cipher, mode, or proposal components cannot be used together.
Inspect the complete transform set as one proposal. Individual cipher, integrity, and key-exchange transforms can each be valid while their combination is disallowed for the selected IPsec mode.
What to inspect
- Inspect the full transform combination, not only the failing algorithm.
- Compare local and peer proposals.
- Check whether AH, ESP, transport, tunnel, or AuthIP-specific settings were mixed incorrectly.
