Setting the idle timeout time
The idle timeout period is the amount of time that an administrator will stay logged in to the GUI without any activity. This is to prevent someone from accessing the FortiGate if the management PC is left unattended. By default, it is set to five minutes.
A setting of higher than 15 minutes will have a negative affect on a security rating score. See for more information.
To change the idle timeout in the GUI:
- Go to System > Settings.
- In the Administration Settings section, set the Idle timeout to up to 480 minutes.
- Click Apply.
To change the idle timeout in the CLI:
config system global set admintimeout <integer> end
