What happend when licence expired

You can' t use Webfilter and so on and you don' t get newer AV/IPS Signatures (But the old one keep working).

let provide more details . All fortiguard service will cease to update and things like webfilter and categories will NOT work 100% correctly. If my memory serve me right of you enable webfilter and category on an " unlicensed" fortigate you will get a warning of traffic being potentially blocked if you select categories The IPS will continue to function with the last installed IPS-DB. You can always manually update the IPS-signature DB if you had access & the same for AV, but that would not be un-ethical. With both IPS and url-filtering, you can write custom rules and apply those and have limited protection. Email AS rating will also not work. So back to your problem, you probably have a webfilter policy in placed. You will need to remove ALL webfiltering from any security profile or if you have any custom url filtering, you just uncheck the category box. btw: I manage a private 1st grade school like that, they have a few FGT models with no licensing but only need access to a few education website. So we listed all URL for access in our custom filter.

Hy, Thank you for your answers. Now practicaly i have the following choice: 1) buy subscription and all the service are back and functional 2) delete all the policy and leave the web traffic free Is correct?

No not delete the fwpolicy but remove the UTM security profile from the firewall policies. I think that' s what you meant how long has the FGT been out of contract?
