I still can't find explanation to why UDP ports like 10400 are used. Are these ports needed to be open or not? Every packet which comes to these is dropped by my firewall!
- I am not sure about those ports, however, the assessment tool will help you understand if you will have issues in your current environment
- The assessment tool says "Relay connectivity and Qos (Media Priority) check is successful for all relays.", but still many packets are dropped from 52.112 or 52.114 ip addresses that aim to UDP ports like 10400 or 10500 etc
