I'm trying to setup a new Server 2012 Domain Controller as an authoritative time server using an external NTP server as a source. The TMG client is insalled and the services are running, no issues there.
The problem is that NTP traffic (port 123 UDP) doesn't seem to be hitting our TMG servers. It's bypassing TMG and going straight to our WAN firewall where it's getting blocked. How do I go about forcing NTP traffic from the domain controller to go through TMG?
