Hi,

We are planing to deploy Network Time Server in our Organization.

According to the architecture , Stratum 2 server will be responsible to 
provide correct time to Stratum 3 server and client ( Other servers) will 
synchronize with Stratum 3 server for obtaining correct time. Stratum 2 
server will synchronize with Stratum 1  server. 

We will use NTP 4.2.6p3 

Is it mandatory to open UDP port 123  between Stratum 2 and Stratum 3 
server also between Stratum 3 and Client Machine for time synchronization? 


Can we use any customized port instead of UDP 123 for time 
synchronization? 

Please suggest. 

Thanks and Regards,
