I am having a problem with NTP. My network setup looks like this:
2821 Router <-> ASA 5510 <-> W2k3 DC
I have the router pulling time from a NIST NTP server. I want the W2k3 DC to pull from the router.
I have opened a hole in the firewall to allow the router to pass UDP 123 to the outside interface on the ASA. I have setup a NAT translation to translate to the W2k3 DC's private IP.
This is what I am getting from the debug on the router:
Aug 4 20:10:06.369: NTP: packet from x.x.x.x failed validity tests 0E
Aug 4 20:10:06.369: Bogus Packet received
Aug 4 20:10:06.369: Protocol unsynchronized
Aug 4 20:10:06.369: Peer/Server delay/dispersion boundary check failed
This is the router config:
ntp clock-period 17180270
ntp server 18.104.22.168
For the W2K3 DC, I have the router IP in the following reg key:
I can not find that "failed validity tests 0E" specifically anywhere.
Any suggestions? Thank you in advance.
