NTP servers under DHCP how to use?

evewes · Jul 3, 2009, 4:42 PM

I have 5 AP with dd-wrt under a switch on interface lan , and want to get time from pfsene.
Is it possible to set something under DHCP/NTP servers and adress it from AP to get time?

From web GUI, look at Services -> OpenNTPD

The service is running, but i dont understand how to adress NTP from my AP to get time and not what to fill in the NTP-services field under DHCP?

How to tell dd-wrt the identity of the NTP server isn't really a pfSense issue UNLESS the dd-wrt APs get their IP address from pfSense by DHCP and you want the pfSense DHCP server to tell them which NTP server to use. If that's the case then from the pfSense web GUI, Services -> DHCP Server for each relevant interface in the NTP section click the Advanced button and then specify the IP address of up to two NTP servers (in this case the appropriate pfSense IP address).

You might need to ask the dd-wrt people if dd-wrt takes any notice of the NTP server assignment by DHCP.

Perhaps dd-wrt has an option for configuring the NTP server. (My ADSL modem/router does.)

Yes, i use PFSENSE as a router and AP (dd-wrt) without dhcp.
My first problem was that AP could not reach external ntp-server, i solved it today with google.
I had missed to set DNS adress in AP to PFSENSE router.
The time came directly. Now shall i test to run time from PFSENSE. I dont need it now, just for a test.
Thanks for your help.
