Sorry! I removed the mails so I have to post another one. I stopped the iptables on the three nodes. Ping it's working OK (pruebaborja to clienteprueba / clienteprueba to pruebaborja....).
My /etc/networks/interfaces - node: pruebaborja Masternode #The loopback network interface auto lo iface lo inet loopback #The primary network interface auto eth0 iface eth0 inet dhcp clienteprueba and clientepruebados auto lo ifface lo inet loopback My interface is Auto (eth0) on the three nodes. Do you want to see "ifconfig" also? Thank you again or answer
