NTP server issues

  • I’ve configured the NTP server in pfsense, but my Netgear switch times out when trying to poll the NTP server. I don’t know how to resolve this issue. I get this is probably a Netgear config issue, but I am hoping someone will be able to assist. Within the Netgear SNTP setup, one has to select either Unicast or Broadcast. It defaults to Unicast, but since my NTP server is on the pfsense box, should I select Broadcast - or does it matter? I’ve selected IPv4 as the server type (as opposed to DNS), input my pfsense IP address ( as the NTP server address, and selected Version 4 for NTP. The message the switch gives is that “Request Timed Out” and Address type “unknown”. Any suggestions?

    Are other hosts able to sync against the pfSense ntp service?

    Run a packet capture on the internal interface filtered by the switch IP and port 123. Do you see requests? Do you see pfSense respond?
