Hello, I'm seeing an odd NTP problem on a couple of Redhat servers here. Basically the NTP client is on a firewalled DMZ, away from the NTP server. NTP updates via ntpq work fine on the local NTP server subnet, but it isn't working for hosts on the firewalled DMZ. We've checked ports on the firewall, and 123/UDP is open. In addition, we see packets incrementing when we use the "iostat" command in ntpdc, and don't see any dropped or ignored packets in iostat either. Any ideas?
Does the firewall allow port 123 in _both_ directions? NTP requires unrestricted access to 123/udp for _both_ source and destination.
Thanks, Mike.
