The edge gateway runs a Network Time Protocol (NTP) server and real-time clock, which allows the entire machine line to sync their time. This guarantees identical internal clocks across the entire machine.

For frequently asked questions and solutions with issues, see NTP server FAQ and known issues.

How can I use the NTP server?

Follow these steps to have your machine utilize the edge gateway's NTP server:

Open the NTP settings on your machine and enter the edge gateway's LAN IP address as the NTP server.
Apply the correct time zone in your machine's time settings.
- The NTP protocol provides the time in UTC, meaning without time zone. To convert UTC to local time, you'll need to apply the local time zone in the machine settings. This cannot be configured in your edge gateway.

Configure the time synchronization method

The edge gateway can synchronize its internal clock using one of these methods:

Approximate synchronization using HTTPS (default).
- The edge gateway will sync the time every 24 hours with the IXON API (HTTPS, TCP, port 443).
Precise synchronization using NTP.
- The edge gateway will sync the time more accurately and more frequently with the entered NTP servers (NTP, UDP, port 123).
- Make sure that the local company firewall allows this traffic through. If this is not allowed through, the edge gateway will not be able to sync its time and devices behind the edge gateway may even reject the out-of-sync time from the edge gateway's NTP server, causing their time to not be in sync with each other.

To change the method from the default approximate synchronization to precise synchronization using NTP servers, select one of the configuration methods below.

IXON Cloud
Local web interface

IXON Cloud

The steps below explain how to configure the time synchronization method via the IXON Cloud.

Go to Fleet Manager > Devices and click on your device name.
Go to Network > WAN.
At Time synchronization, select the method Synchronize with time server and enter the desired NTP servers.

Local web interface

Supported hardware

SecureEdge and SecureEdge Pro, firmware 5.9 and up (upgrade)
IXrouter3, firmware 3.26 and up (upgrade)

To configure the time synchronization method via the local web interface, select your edge gateway model:

SecureEdge and SecureEdge Pro

Connect your computer to one of the LAN ports.
- The local web interface is not accessible from the WAN side (Cloud port and also OT/LAN port when it's configured as WAN2).
Open a new browser tab, go to the edge gateway's LAN IP address, and log in.
- The default LAN IP address is 192.168.140.1.
- Make sure that your laptop has an IP address in the same range. You may need to configure this manually. There are many online guides on this if you need a step by step guide.
- The default username is admin.
- The default password (PW) is printed on the side of the edge gateway.
- The number of login attempts is limited per time window, in compliance with cybersecurity standard IEC 62443-4-2. By default, the number of login attempts is limited to 5 per 1 minute, replenishing a login attempt every 1 minute. We recommend you configure this to align with your corporate security policy. Do so by logging in and going to Administration > Authentication.
- You can change the password by logging in and going to Administration > Change password.
Go to Miscellaneous > Time Synchronization.
At NTP Client, add the desired NTP servers.
- If no servers are entered, the edge gateway will use approximate synchronization using HTTPS.
Click on Submit changes.

You have now made the changes in the edge gateway, but these are not yet present in the IXON Cloud. You will need to import these changes to the IXON Cloud to avoid unwanted configuration changes later on.

Wait a moment for the edge gateway to report its new configuration to the IXON Cloud. This usually takes less than a minute.
Go to Fleet Manager > Devices and click on your device name.
Open the sync optionsand select Import config from device.

IXrouter3

Connect your computer to one of the LAN ports.
- The local web interface is not accessible from the WAN side (Internet port).
Open a new browser tab and go to the edge gateway's LAN IP address.
- The default LAN IP address is 192.168.27.1.
- Make sure that your laptop has an IP address in the same range. You may need to configure this manually. There are many online guides on this if you need a step by step guide.
Go to Configuration and log in.
- The default password (PW) is printed on the side of the edge gateway.
- If there is no password printed on the side, this edge gateway was manufactured before the local web interface was created. That means it does not have a password and you cannot proceed using this method. Instead, use the IXON Cloud method. Additionally, once the edge gateway is online and has a VPN connection, we can configure a password for you. Please then contact us by granting us support access at Fleet Manager > Tools and tell us the serial number of the edge gateway.
- If you enter an incorrect password multiple times in a row, you'll need to wait roughly 5 minutes before you can try again. The number of attempts is limited to 5 attempts per 5 minutes.
- You can change the password by logging in and going to Account in the bottom left corner.
Go to Miscellaneous > Time Synchronization.
At NTP servers, enter the desired NTP servers.
- If no servers are entered, the edge gateway will use approximate synchronization using HTTPS.
If you haven't already, Apply your settings.

Wait a moment for the edge gateway to report its new configuration to the IXON Cloud. This usually takes less than a minute.
Go to Fleet Manager > Devices and click on your device name.
Open the sync optionsand select Import config from device.
