Hello all. I have a Cisco 2811 router on a lan network. I have NTP turned on on this machine, and have assigned a valid NTP server that another edge router we have uses. Internally, local machines asking this router for NTP get results just fine. However, I have several remote locations that need to be able to ask this router for NTP and get it. So far, no remote location is getting NTP from the router.
On a linux machine, I get the following message:
7 Aug 13:21:19 ntpdate[15929]: no server suitable for synchronization found
The router is synchronized though.
Clock is synchronized, stratum 8, reference is 127.127.7.1
nominal freq is 250.0000 Hz, actual freq is 249.9942 Hz, precision is 2**18
reference time is CE26E447.CA44C60F (13:35:03.790 EST Fri Aug 7 2009)
clock offset is 0.0000 msec, root delay is 0.00 msec
root dispersion is 0.02 msec, peer dispersion is 0.02 msec
Any help would be appreciated.

Make sure udp/123 is permitted between your router and your remote locations.

Thanks, that wasn't the issue, but it helped me find the issue while check for that. Apparantly my router wasnt receiving its ntp from the server I requested. It was trying to use itself. I removed all NTP information and redid it, and that fixed the problem.
