How to Configure Custom NTP Servers on FortiGate

Introduction:

FortiGate firewalls are known for their robust security features, but ensuring accurate timekeeping is equally important. Network Time Protocol (NTP) plays a crucial role in maintaining synchronized clocks across your network devices, and FortiGate offers flexibility in this regard. While the default configuration leverages FortiGuard time servers, you might prefer using your own custom NTP servers.

Why Use Custom NTP Servers?

There are a few reasons to opt for custom NTP servers:

• Security: Maintaining control over time synchronization within your network perimeter might be a security requirement for your organization.
• Compliance: Specific regulations might mandate the use of internal time servers.
• Performance: In geographically dispersed networks, using local NTP servers can improve time synchronization speed.

Configuring Custom NTP Servers on FortiGate

Consider configuring the NTP server with the following requirements:

1. Primary NTP server: 192.168.20.10
2. Sync interval: 1440 minutes(24 Hours)

config system ntp
    set ntpsync enable
    set type custom
    set syncinterval 1440
    config ntpserver
        edit 1
            set server "192.168.20.10"
        next   
    end
end

Conclusion:

Custom NTP configuration in FortiGate empowers you to maintain precise timekeeping within your network based on your specific requirements. By following these steps and considering the additional options, you can ensure your FortiGate device remains synchronized and your network functions seamlessly.
