FortiGate Next Generation Firewall utilizes purpose-built security processors and threat intelligence security services from FortiGuard labs to deliver top-rated protection and high performance, including encrypted traffic.
This article describes the FortiGate GUI access Idle timeout behavior after value change.
FortiGate v7.4.0 and onwards.
For older firmware versions such as 7.2, under System -> Settings -> Administration Settings -> Idle timeout', change the default 5 minutes to 1 minute.
There will be a message 'Your session is about to timeout.' 30 seconds before, it logs out automatically which is 1 minute timeout.
For firmware version 7.4.0 and onwards, no message will appear and the timeout will be cached in the previous value until logout and re-login. The idle timeout will only be applied to sessions created after the timeout period has been changed, so it is NECESSARY to log out and re-login to FortiGate GUI every time the value of idle timeout is modified.
The Fortinet Security Fabric brings together the concepts of convergence and consolidation to provide comprehensive cybersecurity protection for all users, devices, and applications and across all network edges.
