[ScreenOS] Configuring a ScreenOS device as an NTP Server.



Article ID: KB26642 KB Last Updated: 27 Aug 2019Version: 2.0
A ScreenOS security device can also work as an NTP server serving NTP requests from its subnet peers.
How to configure ScreenOS device as an NTP server.
For the device to act as an NTP server, we need to enable NTP server option at the interface level.


  1. Navigate to WebUI page Network > Interfaces > Edit (ethernet0/0) > Basic.
  2. Check the "NTP Server" check box.
  3. Click Apply.



set interface ethernet0/0 ntp-server

Note: If the incoming NTP request from a client device arrives on a different interface than where the NTP server is configured, then you may also need a policy permitting NTP for that to work.
