FortiOS 6.4.2 for a fortigate not connected to the internet

[Rolland]

Hello,

we have upgraded our FG300D (not connected to the internet) from 6.2.0 to 6.4.2 this morning.

After the reboot, the FG asked for a configuration to join Fortiguard servers.

This is impossible : the FG is placed to filter an "internal" link between to sites on the LAN (the other side is a FG (v6.2.5))

Since it failed to connect to the internet, it started, but le licences widget states "unable to connect to Fortiguard servers" and it apparently tries all the time...

Is there a way to desactivate this fortiguard interrogation ?

Is fortigate still able to work without an internet connection ?

Thanx for your help

basically it is able to work without internet. But some features requeire a valid license (webfilters for example). Those will not work if it cannot check for a valid license with the fortiguard servers.

Also UTM Services like webfilter need to connect to fortiguard themselfes (despite the license check) because they need to upgrade the Fortiguard Cathegories for Webfilter or A/V Definitions for antivirus.

The Rest will work without connection to Fortiguard.
