When I enter the command on my second Application server(AS) "mp_replication init -n 2 -r Eth0:0-Node1" the command failed, and answer "All configured NTP servers are down".
I start a wireshark capture do check if the second application can join the NTP server. In the wireshark trace, I can see that the NTP answer to the AS. And after the NTP answer, the AS try to ping the NTP server. 3 secondes after, I receive the answer all configured NTP server are down.
As this flow is not describe in the TCP/UDP Matrix for MeetingPlace, the ping to the NTP server is not allowed, the AS doesn't receive any answer.
Could you confirm that it is a normal behaviour, and that we have to open this flow?
