Cancel this...turns out, our network team had forgot to put a route in for this subnet, as it was a new subnet of our Class B IP range.
All my testing was from a different subnet of the same Class B, but of course the internet time servers are in different subnets entirely.

The design calls for our master clock servers to get their time from several public NTP servers. I initially set this up using Fedora Core 13 running as a VMware server inside our network, and was able to get it to sync up properly: [r...@coruxdev etc]# ntpq -p remote refid st t when poll reach delay offset jitter ============================================================================== +time-a.nist.gov .ACTS. 1 u 44 1024 377 13.884 2.153 7.738 +clock.isc.org .GPS. 1 u 815 1024 377 76.939 -6.417 0.171 *time-b.nist.gov .ACTS. 1 u 937 1024 377 12.309 0.460 4.231 I then took that same config and built it on our DMZ VMware environment, and in spite of being assured that our firewall is allowing UDP 123, I can't get time sync to work: [r...@extux66 ~]# ntpq -p remote refid st t when poll reach delay offset jitter ============================================================================== time-a.nist.gov .INIT. 16 u - 1024 0 0.000 0.000 0.000 clock.isc.org .INIT. 16 u - 1024 0 0.000 0.000 0.000 time-b.nist.gov .INIT. 16 u - 1024 0 0.000 0.000 0.000 I've tried several different NTP troubleshooting documents found on the web, none have helped. I've turned off iptables that was running on the local server, that didn't make a difference. What could possibly be causing this?
