Downgrade signature version

[JayChang]

Hi,

  Is there any way to downgrade WAF signature version to lower version except re-initial firmware ? Thanks.

Hi Jay,

Do you mean downgrade firmware from stock firmware? If that's the case then yes, you can upload a lower version via gui (status-> Update firmware). Afterwards go to Maintenance -> backup & restore and choose the boot firmware.

Hope this helps.

No experience with a FortiWeb but can't you just manually load a signature? Download from Support website. If it isn't there it won't be possible.

Hi Ede,

 Yes, I can download from support website and upload manually. But it failed if upload lower signature version.

Hi Heyro,

  No, I mean downgrade the signature version not firmware version. Thank you.
