Troubleshooting pfSense as a NTP Server (Resolved)
Hi, quick NTP-related question. I am using pfSense (at the IP 10.60.66.30) on AWS and am attempting to use it as a NTP server in my environment.
I seem to have set it up but Ubuntu (at 10.60.66.9) doesn't seem to want to sync with it, showing the following output:

Update 2: Annd solved.. thank you tcpdump. It was a security group setting on AWS... thanks for anyone who read this and was about to help :)
