Every modification I do is copied to the other node. The problem is not between the nodes, if they talk to each other they undestand, as it has been the last 2 years. But, I don't know why, since the new switch (i've just been informed they changed the switch with a new one) there is no outgoing udp traffic from the nodes. And there is no iptables nor selinux nor firewalld activated.
