Description This article describes an issue in which the FortiGate GUI displays an incorrect or misleading warning notification when the Phase 1 and Phase 2 VPN proposals are mismatched.
Scope FortiGate v7.6.3, v7.6.4.
Solution

Starting from v7.6.3, the following warning may appear if the Phase 1 and Phase 2 proposals do not include at least one common encryption/authentication pair:

If this warning is disregarded and the configuration is saved without aligning the encryption/authentication pairs, the GUI may then display:

This behavior is a GUI design issue. Despite the warnings, the VPN comes up successfully, and functionality is not impacted. Only the visual notifications are incorrect, but the underlying configuration operates as expected.

This issue has been resolved in:

  • v7.6.5 (available to download from the Fortinet Support portal). 
  • v8.0.0 (scheduled to be released in April 2026).

 

These timelines for firmware release are estimated and may be subject to change.
