Hi there, A1 - both options are supported - same NTP server or different ones per cluster. A2 - Refer to the RP4VMs Security Configuration Guide for the list of ports  Hope that helps, Idan
Hello,  Can anybody help me ? Thank you.  Q1. Should we use the same NTP servers for all sites ? Or every site can use their own NTP servers when configure the cluster? Q2. What network ports should be opened between two sites ?
