Configure NTP Server



Synchronize the clock on Sophos Firewall with NTP servers.


NTP enables Sophos Firewall to maintain an accurate time and date when receiving updates from a reliable NTP server. Accurate timestamps are critical when correlating events with other systems, troubleshooting, or performing investigative work. Logs and certain cryptographic functions, such as those utilizing certificates, rely on accurate time and date parameters. In addition, rules referencing a Schedule object will not function as intended if the device’s time and date are incorrect.


  1. Go to Administration > Time.
  2. Select the appropriate Time zone.
  3. Select Use pre-defined NTP server or Use custom NTP server. If Use custom NTP server is selected, enter the NTP server IP address.
  4. Click Sync now.
  5. Click Apply.
