I am having trouble using NTP to synchronize time on port 123. I have set up a custom NTP server that listens to port 122, and I have verified that the synchronization works fine using the nettime client on a Windows machine. However, when I try to sync time on port 123, I encounter issues.
I checked the debug monitor on ASDM and noticed that the request is being made to the specific NTP server, but the reply takes approximately two minutes to show up on the monitor.
To clarify, I am trying to sync time using NTP, but I am only experiencing issues with port 123. I have set up a custom NTP server that works fine on port 122, but the problem arises when I use port 123. I have checked the debug monitor on the ASDM, and I can see that the request is being sent to the NTP server, but the response takes a long time to show up.
To fix this issue, I have checked the network and firewall settings to ensure that they are not causing any delays or blocking NTP traffic on port 123. I have also verified that the NTP server is correctly configured and responding to requests in a timely manner. Additionally, I have tried using a different NTP server and client to see if the issue persists.
